More than 80% of children will experience at least one ear infection before they turn three-years-old. Ear infection is one of the top reasons that parents seek medical treatment for their children, causing fever, irritability, and ear pain. Also known as otitis media, an ear infection is caused by fluid buildup behind the eardrum that results in inflammation. It is typically caused by bacteria. According to the Centers for Disease Control (CDC), antibiotics are not a recommended treatment for most ear infections.
Types of Childhood Ear Infections
There are three types of childhood ear infections. Each type has its own distinct set of symptoms that can aid in diagnosis and treatment.
Otitis Media with Effusion (OME) � This results from a fluid buildup that occurs in the middle ear although there are no symptoms or signs of infection. While it can happen when the fluid remains after an ear infection has run its course, other causes may include allergies, previous respiratory infections (like cold or flu), elevation changes, environmental irritants, air travel, and drinking while lying down (usually on the back). Antibiotics are not sufficient for this type of ear infection.
Acute Otitis Media (AOM) � This type of ear infection is the most common, affecting the middle ear, and is marked by infection, swelling, and trapped fluid behind the eardrum. Symptoms may include an earache and fever. It may be seasonal (most earaches occur in the winter and fall months), environmental pollutants (second-hand smoke), age (children under two years of age are more prone to earaches), and attendance at daycare. AOM may also be caused when the fluid from OME becomes infected. Antibiotics are sometimes prescribed for more acute cases.
Chronic Otitis Media with Effusion (COME) � This can be a serious condition if left untreated. It occurs when fluid in the middle ear continuously returns or remains trapped for a long time. Often infection is not present, and there are no symptoms. Children with COME have a more difficult time fighting new infections, and they may suffer from hearing damage or loss.
Risk Factors for Ear Infections
Children are more prone to ear infections than adults. This is because the eustachian tubes (connecting the middle ear to the upper part of the throat) are smaller in children and more level. This means that the fluid does not drain as easily and if a respiratory illness like a cold causes the eustachian tubes to become blocked or swollen, the fluid may become trapped because it can�t drain. Other risk factors include:
Drinking while laying on their back
Respiratory illness such as a cold
Allergies
Air travel (changes in air pressure)
Cigarette smoke and other environmental pollutants
Changes in elevation
Childhood Ear Infection Symptoms and Signs
Most of the time children get ear infections before they are old enough to verbalize their discomfort so parents must rely on telltale sure signs and symptoms.
Crying and fussiness
Fever (most prevalent in younger children and infants)
Pulling or tugging at the ears
Difficulty hearing or failure to respond to quiet sounds
Fluid draining from the ear
Difficulty sleeping
Balance problems or clumsiness
Chiropractic for Ear Infections
Several studies have shown Chiropractic for ear infections to be an effective, natural, antibiotic-free treatment. While full spine adjustments are commonly used, other techniques include occipital subluxation, atlas subluxation, and axis subluxations.
Chiropractic care not only treats ear infections, but it also improves their overall health and ability to function. It has a strong focus on whole-body wellness so the chiropractor may recommend diet and lifestyle adjustments in addition to treatment. Parents need to realize that they have a choice when it comes to the type of care their children receive for ear infections and other kinds of illnesses.
The tendons are powerful soft tissues which connect the muscles to the bones. One of these tendons, the quadriceps tendon, works together with the muscles found at the front of the thigh in order to straighten the leg. A quadriceps tendon rupture can affect an individual’s quality of life.
A quadriceps tendon rupture can be a debilitating injury and it usually requires rehabilitation and surgical interventions to restore knee function. These type of injuries are rare. Quadriceps tendon ruptures commonly occur among athletes who perform jumping or running sports.
Quadriceps Tendon Rupture Description
The four quadriceps muscles come together above the kneecap, or patella, to form the quadriceps tendon. The quadriceps tendon joins the quadriceps muscles into the patella. The patella is connected to the shinbone, or tibia, by the patellar tendon. Working collectively, the quadriceps muscles, the quadriceps tendon, and the patellar tendon, straighten the knee.
A quadriceps tendon rupture can be partial or complete. Many partial tears don’t completely disrupt the soft tissues. However, a full tear will divide the soft tissues�into two parts. If the quadriceps tendon ruptures entirely, the muscle is no longer attached to the kneecap or patella. As a result, the knee is unable to straighten�out when the quadriceps muscles contract.
Quadriceps Tendon Rupture Causes
A quadriceps tendon rupture frequently occurs due to an increased load on the leg where the foot is planted and the knee is somewhat flexed. By way of instance, when landing from an awkward jump, the power is too much for the soft tissues to bear, causing a partial or complete tear. Tears may also be due to falls, direct impacts to the knee, and lacerations or cuts.
A weakened quadriceps tendon is also more likely to rupture. Several factors may result in tendon weakness, including quadriceps tendinitis, the inflammation of the quadriceps tendon, called quadriceps tendinitis. Quadriceps tendinitis is one of the most common sports injuries in athletes who participate in sports or physicial�activities which involve jumping.
Weakened soft tissues may also be brought on by diseases that interrupt blood flow to the knee or patella. Utilizing corticosteroids and some antibiotics have also been connected to weakness associated with quadriceps tendon ruptures. Immobilization for an extended period of time can also decrease strength in the quadriceps tendons. Finally, quadriceps tendon ruptures can occur due to dislocations and/or surgery.
Quadriceps Tendon Rupture Symptoms
A popping or tearing feeling is one of the most common symptoms associated with a quadriceps tendon rupture. Pain followed by swelling and inflammation of the knee�might make the individual unable to straighten out their knee. Other symptoms of a quadriceps tendon rupture include:
An indentation at the top of the kneecap or patella of the affected site
Bruising
Tenderness
Cramping
Sagging or drooping of the kneecap or patella where the tendon tore
Difficulty walking because the knee is buckling or giving away
Quadriceps Tendon Rupture Evaluation
The healthcare professional will perform an evaluation to diagnose a quadriceps tendon rupture by first discussing the patient’s symptoms�and medical history.�After talking about the patient’s symptoms and medical history, the doctor will conduct a comprehensive evaluation of the knee.
To ascertain the precise cause of the patient’s symptoms, the healthcare professional will examine how well it is possible to stretch, or straighten,�the knee. Although this area of the evaluation can be debilitating, it’s essential to diagnose a quadriceps tendon rupture.
To verify a quadriceps tendon rupture diagnosis, the doctor may order some imaging tests, like an x-ray or magnetic resonance imaging, or MRI, scan. The kneecap moves from place once the quadriceps tendon ruptures. This can be quite evident on a sideways x-ray perspective of the knee.
Complete tears may frequently be identified with x-rays alone. The MRI can reveal the quantity of tendon torn along with the positioning of the tear. From time to time, an MRI will also rule out another injury with similar symptoms. Diagnostic imaging is helpful in the evaluation of sports injuries.
The quadriceps tendon is the large tendon found just above the kneecap, or patella, which allows us to straighten out our knee. While the quadriceps tendon is a strong, fibrous cord which can withstand tremendous amounts of force, sports injuries or other health issues may lead to a quadriceps tendon rupture. Quadriceps tendon ruptures are debilitating problems which can affect a patient’s quality of life.

Quadriceps Tendon Rupture Treatment
Non-Surgical Treatment
A majority of partial tears react well to non-surgical treatment approaches. The doctor may advise the patient to utilize a knee immobilizer or brace to allow the quadriceps tendon to heal. Crutches will help avoid placing weight onto the leg. A knee immobilizer or brace is used�for 3 to 6 months.
Once the initial pain, swelling, and inflammation have�decreased, alternative treatment options, such as chiropractic care and physical therapy, can be utilized. A doctor of chiropractic, or chiropractor, utilizes spinal adjustments and manual manipulations to carefully correct any spinal misalignments, or subluxations, which may be causing problems.
Furthermore, chiropractic care and physical therapy can provide lifestyle modifications, including physical activity and exercise programs to help speed up the recovery process. The patient may be recommended a variety of stretches and exercises to improve strength, flexibility and mobility. The healthcare professional will determine when it’s safe to return-to-play.
Surgical Treatment
Many individuals with complete tears require surgery to repair a quadriceps tendon rupture. Surgical interventions depend on the patient’s age, actions, and prior level of function. Surgery for quadriceps tendon ruptures involves re-attaching the tendon to the kneecap or patella. Surgery is carried out with regional spinal anesthetic or general anesthetic.
To reattach the tendon, sutures are put in the tendon and then threaded through drill holes at the kneecap. The stitches are attached in the base of the kneecap. The�physician will tie the sutures to find the ideal tension in the kneecap or patella. This will also make sure that the place of the kneecap closely matches that of the uninjured patella or kneecap.
A knee immobilizer, brace or a long leg cast may be utilized following the surgery. The patient may be allowed to set weight on their leg by means of crutches. Stretches and exercises are added into a rehabilitation program by a chiropractor or physical therapist after a surgical intervention.
The precise timeline for chiropractic care and physical therapy following a surgery for those patients that require it will be individualized personally. The patient’s rehabilitation program will be contingent upon the kind of tear, their surgery, medical condition, along with other requirements.
Conclusion
The majority of patients can return to their original routines after recovering from a quadriceps tendon rupture. The individual’s return will be addressed very carefully by the healthcare professional.�The scope of our information is limited to chiropractic and spinal health issues.

Additional Topic Discussion: Relieving Knee Pain without Surgery
Knee pain is a well-known symptom which can occur due to a variety of knee injuries and/or conditions, including�sports injuries. The knee is one of the most complex joints in the human body as it is made-up of the intersection of four bones, four ligaments, various tendons, two menisci, and cartilage. According to the American Academy of Family Physicians, the most common causes of knee pain include patellar subluxation, patellar tendinitis or jumper’s knee, and Osgood-Schlatter disease. Although knee pain is most likely to occur in people over 60 years old, knee pain can also occur in children and adolescents. Knee pain can be treated at home following the RICE methods, however, severe knee injuries may require immediate medical attention, including chiropractic care.
Bone neoplasms and tumor-like conditions affecting the knee can be benign or malignant. Age at Dx is crucial for DDx
In patients <40: Benign bone neoplasms: Osteochondroma, Enchondroma are relatively frequent
Fibrous cortical defect (FCD) & Non-ossifying fibroma (NOF) are particularly frequent in children
Giant cell tumor (GCT) is the m/c benign neoplasm of the knee in patients between 20-40 years of age
Malignant bone neoplasms in <40: m/c Osteosarcoma and 2nd m/c Ewing sarcoma
In patients >40: malignant neoplasms: m/c are secondaries d/t bone metastasis. Primary bone malignancy:�the m/c
Multiple Myeloma (MM). Less frequently:�a 2nd�peak of Osteosarcoma (post-radiation or Paget�s), Fibrosarcoma or Malignant�Fibrous�Histiocytoma�(MFH) of bone.
Clinically: knee pain, pathological fracture
Some tumor-like conditions like FCD/Non-ossifying fibroma are asymptomatic and may regress spontaneously. Occasionally NOF may present with pathologic fracture. N.B. any knee/bone pain in a child/adolescents should be�treated with clinical suspicion and adequately investigated.
Imaging: 1st step: radiography
MRI with T1+C is crucial for lesion characterization/regional extent, staging and pre-operative planning. CT may�help with pathologic Fxs detection. If malignant bone neoplasms considered, CXR/CT, PET-CT to investigate�metastatic spread and staging are important
Imaging Approach Bone Neoplasms
Approach to imaging Dx of bone neoplasms includes age, bone location (epiphysis vs. metaphysis vs. diaphysis), zone of transition surrounding the lesion, periosteal response, type of matrix, permeating or moth-eaten destruction vs. sclerotic, ground-glass, osteoid, cartilaginous matrix, soft tissue invasion, etc.
Key x-radiography features to DDx benign vs. malignant bone neoplasm:
Zone of transition: lesion is geographic with a narrow zone of transition vs. ill-defined wide zone of transition suggesting aggressive bone resorption
What type of bone destruction occurred: soap-bubbly appearance vs. osteolytic vs. osteosclerotic changes
Is there a round-glass matrix? Is there a well-defined rim of the sclerotic border with septations potentially suggesting slow growth and encapsulation like most benign processes.
Periosteal proliferation: solid vs. aggressive spiculated/sunburst/hair-on-end with local soft tissue invasion and Codman triangle (study next slide)
FCD & NOF
FCD & NOF or more appropriately Fibroxanthoma of the bone are benign bone processes that m/c seen in children. DDx based on the size with FCD presenting as <3-cm and NOF >3cm lesion composed of a fibrous heterogeneous matrix. FCD are asymptomatic and may regress in many cases. Some may progress to NOF. Location: identified in the knee region as an eccentric cortical based lesion.
FCD must be DDx from an avulsive irregularity d/t repeated stress along Linea aspera by extensors muscles
Dx: radiography
Management: leave-me-alone lesion. Occasionally NOF may progress and lead to pathologic fracture requiring orthopedic consult
Osteochondroma
Osteochondroma: m/c benign bone neoplasm. Knee is the m/c location. Contains all bone elements with a cartilaginous cap. Presented as pedunculated or sessile bone exostosis pointing away from the joint.
1% malignant degeneration to chondrosarcoma if solitary lesion and 10-15% in cases of HME
Other complications: fracture (top left image) pseudoaneurysm of the Popliteal artery, adventitious bursa formation
Hereditary Multiple Exostosis (HME)– autosomal dominant process. Presents with multiple osteochondromas (sessile-type dominates). May lead to limb deformities (Madelung deformity, coxa valga) reactive ST pressure, malignant degeneration
Dx: radiography, MRI helps to Dx malignant degeneration to chondrosarcoma by changes in size and activity of cartilaginous cap (>2-cm in adults may manifest malignant degeneration). MRI will also help with Dx of regional complications
HME & Knee Pain
37-y.o male with HME and knee pain. Axial T1, T2 and STIR MRI slices at the popliteal region. Large cartilaginous cap and possible compression of the popliteal artery by osteochondroma. MRA was performed to evaluate popliteal A. pseudoaneurysm (large arrow). Pathology specimen obtained from the cartilaginous cap showed increased cellularity suggestive of malignant degeneration. Operative care was planned
Giant Cell Tumor (GCT) aka Osteoclastoma
GCT- is a relatively common primary benign bone neoplasm. Age 25-40. M>F slightly.
GCT is the M/C benign sacral tumor. In 50% of cases, GCT occurs about the knee.
GCT is histologically benign, but lung Mets may develop esp. if in distal radius and hands, often termed Malignant GCT
<1% unresponsive/recurring GCTs may undergo malignant transformation to high-grade bone sarcoma
Pathology: histologically composed of osteoclasts-multinucleated giant cells with stromal cells derived from precursors monocyte-macrophage type. Produces cytokines and osteolytic enzymes. GCT may contain blood and associated with secondary Aneurysmal Bone Cyst (ABC)
Clinically: knee pain unresponsive to conservative care. Pathologic Fx may occur
Imaging: always begins with radiography followed by MRI and surgical biopsy that are crucial to Dx.
Rx: operative with curettage and cementing, a surgical appliance may be used if pathological fx present and cortical breach. In more severe cases other options available
Radiologic-Pathologic Dx
Radiologic-pathologic Dx: osteolytic and soap-bubbly lesion typically involving metaphysis and into epiphysis (classic key feature) with subarticular extension. Zone of transition is generally narrow but occasionally in aggressive lesions wide zone of transition may be seen.
MRI: low T1, highT2/STIR, characteristic fluid-fluid levels noted that are present in GCT and ABC. Histology is crucial to Dx.
DDx: ABC, Brown cell tumor of HPT (osteoclastoma), Telangiectatic Osteosarcoma
Radiological rule: if the physeal growth plate is present Dx of GCT is taken off the list in favor of chondroblastoma and vice versa.
Primarily Soap-Bubbly Appearance of GCT
Coronal, Fat-Sat Sagittal & Axial MRI Slices of GCT
T1 coronal, T2 fat-sat sagittal and T2 axial MRI slices of GCT. Typically: low T1, highT2/STIR and fluid-fluid levels
Characteristic MRI Appearance of GCT
Fluid-fluid levels d/t different composition of blood degradation products
Important DDx: ABC
Malignant Neoplasms About the Knee
In children and very young adults, m/c primary malignant neoplasm is central aka intramedullary (osteogenic) osteosarcoma (OSA). Second peak of OS: >70 y.o d/t Paget�s (1%) and/or post radiation OSA.
The knee is the m/c location of OSA (distal femur, prox. Tibia)
A 2nd m/c malignant pediatric primary is Ewing sarcoma.
In adults >40 y.o. the m/c primary is Multiple Myeloma (MM) or Solitary Plasmacytoma
Overall m/c bone neoplasms in adults d/t bone Mets from lung, breast, prostate, renal cell, thyroid (discussed)

CT scanning occasionally helps to evaluate pathological fracture
Central (Intramedullary) Osteosarcoma (OSA)
m/c age: 10-20. m/c location: knee, males>females. Increased risk in some
congenital syndromes and mutation of the retinoblastoma gene: Rothmund-Thompson AR syndrome.
Early Dx is important d/t 10-20% present with Lung Mets at Dx. Prognosis depends on stages. Early stages with local bone invasion and no
mets 76% of survival.
Rx: limb salvage procedures preferred with 8-12 weeks of chemo, amputation if encased neurovascular tissue, path Fx, etc.
Imaging: radiography and MRI.
Clinically: bone pain, Inc. Alkaline Phosphatase
Chest CT if lung Mets considered
Classic Rad Features of OSA
Osteoid forming a sclerotic mass with aggressive hair-on-end/speculated/sun-burst periosteal reaction, Codman’s triangle and soft tissue invasion. Order MRI for staging and extent. Chest CT is crucial for Lung Mets dx.
MRI is Crucial for Dx/Staging
Note sagittal T1 (left) and STIR (right) MR slices: large mass extending from distal femoral metaphysis to remaining shaft. A low signal on T1 and high on STIR d/t marrow invasion with edema, hemorrhaging and tumor invasion. Local ST invasion seen (white arrows). Periosteal lifting and Codman�s triangle (green arrow) are additional signs of aggressive neoplasm.
Note an interesting feature that the epiphysis is spared d/t physeal plate serving temporarily as an additional barrier to the tumor spread.
Ewing Sarcoma
Ewing sarcoma: age: 2-20, uncommon in black patients. 2nd m/c highly malignant bone neoplasm in children that typically arises from medullary cavity (Round cell tumors). Key symptom: bone pain that may mimic infection (ESR/CRP/WBC) Considered PNET Key Rad Dx: aggressive moth-eaten/permeative lucent lesions in the shaft of long bones with sizeable soft tissue invasion/typical onion skin periostitis. May produce saucerisation May affect flat bones. May appear as sclerotic in 33%. Early lung Mets (25-30%) bone-to-bone Mets Poor prognosis if delayed Dx. Imaging steps: 1st step x-rad, MRI is v. important followed by a biopsy. CXR/CT PET-CT Rx: combined rad-chemo, operative.
Note aggressive expansile osteolytic lesion in the distal femur metaphysis into epiphysis. No periosteal reaction present. Following further work up with abdominal and chest CT scanning, Dx of Renal cell carcinoma was established
Distal Mets into lower extremity are more common with lung, renal cell, thyroid and breast CA.
Renal cell and Thyroid will typically present with aggressive osteolytic expansile mass aka �blowout Mets.�
In general, imaging approach should consist of Radiographic knee series, followed by MRI if x-rays are unrewarding
Tc99 Bone scintigraphy is the modality of choice to evaluate metastatic bone disease
Soft Tissue Neoplasms About the Knee
Malignant fibrous histiocytoma (MFH) reclassified as Pleomorphic Undifferentiated Sarcoma (PUS) is the m/c S.T. sarcoma. MFH is aggressive biologically with poor prognosis M>F (1.2:1) 30-80 with a peak in a 6th decade. 25-40% of all adults sarcomas m/c extremities. Retroperitoneum next (worst prognosis d/t late Dx and large growth w/o symptoms) Clinically: painful, hard mass typically about the knee or thigh. Histology: poorly differentiated/undifferentiated malignant fibroblasts, myofibroblasts, and other mesenchymal cells Imaging: MRI is the modality of choice with T1, T2, T1+C. Typically appears as an aggressive heterogeneous mass intermediate to low signal on T1 and high signal on T2 with areas of necrosis and enhancement on T1+C. May appear misleadingly encapsulated w/o true capsule Management: operative with radiation and chemotherapy. Tumor depth is crucial for prognosis. 80% 5-year survival if <5cm deep in ST and 50% if >5-cm deep in ST.
Synovial Sarcoma
Synovial sarcoma: common malignant ST neoplasm esp. in younger patients or older children/adolescents. M/C found in knee area Clinically: can present slowly as a palpable mass in the extremity often ignored d/t slow growth Imaging is the key: radiography may reveal ST. density/mass. Some synovial sarcomas may show calcification and mistaken for Myositis Ossificanse or heterotopic bone formation MRI with T1, T2 and T1+C are Dx modality of choice. Other modalities: US, CT are non-specific DDx: MFH Management: operative, chemo-radiation Prognosis: variable depending on size, invasion, metastasis
When dealing with a sports injury or a similar type of injury, many people are familiar with the R.I.C.E. protocol for injury care. R.I.C.E. stands for Rest, Ice, Compression, and Elevation and has long been used when treating everything from sprained ankles to banged up knees. With acute injury patients, experts recommend adding �P� for protection because of the protection of the area is vital in the healing process. It is crucial that this is implemented as soon after the injury as possible and it should be maintained for anywhere from 24 hours to 72 hours afterward. Of course, this depends on the severity of the injury.
P is for Protection: Injuries hurt and pain can be a good thing because it prevents you from further injuring that area. It encourages you to protect it.
It is essential to listen to your body and protect the injured area through full or partial immobilization and restricted use. The way you do this depends on the body part.
An arm or shoulder injury can be protected with the use of a sling. An ankle injury may require a brace or splint, and you may have to avoid or limit weight bearing for a while. This means using crutches a walker, or a cane.
R is for Rest: The body needs rest to heal. This could mean complete rest, but in many cases, it means what is known as �relative rest.� This means that it allows for enough rest to heal but is not entirely restrictive which could slow or inhibit recovery.
This means avoiding activities that are stressful to the area to the point that they cause pain or that they might compromise healing. Many times, though, some movement is a good thing, even beneficial. Some gentle movements can speed recovery.
Isometric contractions of the muscles and joints that surround the injury and even some range of motion exercises can help. The key is to keep the movements gentle and to listen to your body for guidance on how much and how far to push.
I is for Ice:Cryotherapy or cold treatments can come in the form of actual ice, or there can be other types such as a cold soak. When treating acute injuries at home, the best known, and probably most straightforward way is to put some crushed ice in a freezer bag with a zip lock closure and wrap it in a small towel to keep the pack from directly touching the skin.
Frozen vegetables, like green beans, peas, or edamame work well too � remember to use the towel as a barrier between the skin and the pack. You should not use the pack more than 10 to 15 minutes as a time. The recommended cycle is 10 to 15 minutes on and 1 to 2 hours off.
In some cases, you may not be able to apply ice directly to the site. In those cases, you can use the pack at the joint above the affected area. For instance, a tightly wrapped ankle can still benefit from ice, you just apply the ice pack to the back on the knee on the same leg.
C is for Compression: A compression wrap can offer mild support and reduce swelling. Typically, an elastic bandage is used to compress or apply pressure to the injured tissue.
When applying a compression bandage, start it several inches below the area that is injured. It should be applied directly to your skin.
Use some tension as you wrap, but not to the point that it cuts off circulation (characterized by tingling or numbness and the soft tissue should not change color). Wrap the bandage in a figure eight configuration or spiral, depending on the area, stopping a few inches above the injury.
E is for Elevation: When an injured joint or extremity is not elevated, fluid can pool in the area and swelling can occur. This can lead to increased pain and limited range of motion. Elevation helps prevent these things from happening and can even help to speed up recovery.
The key to elevation is positioning the injured area at a level that is above the heart. The most effective way to accomplish this is to keep the area elevated as much as possible while awake and prop it up with pillows while sleeping for at least the first 24 to 48 hours. Some injuries may require more time though, so listen to your body.
Types, location, and stability of tears are v. important during MRI Dx
Vertical/longitudinal tears especially occur in acute ACL tears. Some longitudinal tears found at the periphery or “red zone” may heal
Bucket handle tear: longitudinal tear in the inner edge that is deep and vertical extending through the long axis and may displace into a notch
Oblique/flap/parrot-beak are complex tears
Radial tear at 90-degree to plateau
Axial T2
Axial T2 WI fat-sat and coronal STIR slices of the posterior horn of the medial meniscus.
Note a radial tear of the posterior horn of the medial meniscus near the meniscal root. This is potentially an unstable lesion requiring operative care
The meniscus, in this case, is unable to provide a “hoop-stress mechanism.”
MRI Slices Coronal & Sagittal
Fat-sat coronal and sagittal proton density MRI slices revealing horizontal (cleavage) tear that is more typical in the aged meniscus
In some cases, when this tear does not contain a radial component, it may partially heal obviating the need for operative care
T2 w GRE Sagittal MRI Slice
Complex tear with a horizontal oblique and radial component.
This type of tear is very unstable and in most cases may need operative care
Bucket Handle Tear
Bucket handle tear are m/c in the medial meniscus esp. with acute ACL and MCL tear
MRI signs; double PCL sign on sagittal slices
Absent “bow-tie” sign and others
Most cases require operative care
DDx From Meniscal Degeneration
Occasionally meniscal tears need to be DDx from meniscal degeneration which may also appear bright (high signal) on fluid-sensitive MRI
The simplest rule is that if there is a true meniscal tear aka Grade 3 lesion, it always reaches/extends to the tibial plateau surface
The Role of MSK Ultrasound (US) in Knee Examination
MSK US of the knee permits high resolution and dynamic imaging of primarily superficial anatomy (tendons, bursae, capsular ligaments)
MSK US cannot adequately evaluate cruciate ligaments and the menisci in their entirety
Thus MR imaging remains modality of choice
Potential Pathologies Successfully Evaluated by MSK US
Patellar tendionosis/patellar tendon rupture
Quadriceps tendon tear
Prepatellar bursitis
Infrapatellar bursitis
Pes Anserine bursitis
Popliteal cyst (Baker cyst)
Inflammation/joint effusion with synovial thickening and hyperemia can be imaged with US (e.g., RA) especially with the addition of color power Doppler
Patient Presented With Atraumatic Knee Pain & Swelling
Radiography revealed sizeable soft tissue density within the superficial pre-patella region along with mild-to-moderate OA
MSK US demonstrated large septated heterogeneous fluid collection with mild positive Doppler activity on the periphery indicating inflammation d/t Dx of Superficial pre-patella bursitis
Long Axis US Images
Note normal lateral meniscus and fibers of LCL (above bottom image) compared to
Horizontal degenerative cleavage tear along with protrusion of lateral meniscus and LCL bulging (above top image)
Major limitation: unable to visualize the entire meniscus and the ACL/PCL
MRI referral is suggested
Rupture of Distal Tendon of Quadriceps
Note rupture of distal tendon of the Quadriceps muscle presented as fiber separation and fluid (hypo to anechoic) fluid collection within the substance of the tendon
Advantages of MSK US over MRI to evaluate superficial structures:
Dynamic imaging
Availability
Cost-effective
Patient’s preparation
Disadvantages: limited depth of structures, inability to evaluated bone and cartilage, etc.
Osteochondral Knee Injuries (OI)
osteochondral knee injuries can occur in children 10-15 y.o presented as Osteochondritis Dissecance (OCD) and in mature skeleton m/c following hyperextension and rotation trauma, particularly in ACL tear.
OCD-typically develops from repeated forces in immature bone and affects m/c postero-lateral portion of the medial femoral condyle.
OI in mature bone occurs m/c during ACL tears mainly affecting so-called terminal sulcus of the lateral femoral condyle at the junction of the weight-bearing portion opposed to tibial plateau and the part articulating with the patella
Osteochondral injuries may potentially damage the articular cartilage causing secondary OA. Thus need to be evaluated surgically
Imaging plays an important role and should begin with radiography often followed by MR imaging and orthopedic referral.
OCD Knee
95% associated with some trauma. Other etiology: ischemic bone necrosis especially in adults
Other common location for osteochondral injuries: elbow (capitellum), talus
1st step: radiography may detect osteochondral fragment potentially attached or detached
Location: a posterior-lateral aspect of the medial femoral condyle. Tunnel (intercondylar notch) view is crucial
MRI: modality of choice >90% specificity and sensitivity. Crucial for further management. T1-low signal demarcating line with T2 high signal demarcating line that signifies detachment and unlikely healing. Refer to orthopedic surgeon
Management: stable lesion esp. in younger children>off weight-bearing-heals in 50-75%
Unstable lesion and older child or impending physeal closure>operative fixation.
The knee is a made up of a variety of complex soft tissues. Enclosing the knee joint is a fold at its membrane known as the plica. The knee is encapsulated�by a fluid-filled structure called the synovial membrane. Three of these capsules, known as the synovial plicae, develop around the knee joint throughout the fetal stage and are absorbed before birth.
However, during one research study in 2006, researchers found that 95 percent of patients undergoing arthroscopic surgery had remnants of their synovial plicae. Knee plica syndrome occurs when the plica becomes inflamed, generally due to sports injuries.�This often takes place in the center of the kneecap, known as medial patellar plica syndrome.
What are the Symptoms of Knee Plica Syndrome?
The most common symptom of knee plica syndrome is knee pain, although a variety of health issues can also cause these symptoms. Knee pain associated with knee plica syndrome is generally: achy, instead of sharp or shooting; and worse when using stairs, squatting, or bending. Other symptoms of knee plica syndrome can also include the following:�
a catching or locking sensation on the�knee while getting up from a chair after sitting for an extended period of time,
difficulty sitting for extended intervals,
a cracking or clicking noise when bending or stretching the knee,
a feeling that the knee is slowly giving out,
a sense of instability on slopes and stairs,
and may feel swollen plica when pushing on the knee cap.
What are the Causes of Knee Plica Syndrome?
Knee plica syndrome is commonly caused as�a result of an excess of stress or pressure being placed on the knee or due to overuse. This can be brought on by physical activities and exercises which require the individual to bend and extend the knee like running, biking, or utilizing a stair-climbing machine. An automobile accident injury or�a�slip-and-fall accident can also cause knee plica syndrome.
�
Knee plica syndrome, commonly referred to as medial patellar plica syndrome, is a health issue which occurs when the plica, a structure which surrounds the synovial capsule of the knee, becomes irritated and inflamed. Knee plica syndrome can occur due to sports injuries, automobile accident injuries, and slip-and-fall accidents, among other types of health issues. The symptoms of knee plica syndrome may commonly be mistaken for chondromalacia patella. Diagnostic imaging can help diagnose the problem to continue with treatment.
Dr. Alex Jimenez D.C., C.C.S.T. Insight
How is Knee Plica Syndrome Diagnosed?
In order to diagnose medial patellar plica syndrome, the healthcare professional will first perform a physical examination. They will use the evaluation to rule out any other potential causes of knee pain, such as a torn meniscus, tendonitis, and broken bones or fractures. Be sure to talk to your doctor about any physical activities you participate in along with any recent health issues. The healthcare professional might also utilize an X-ray or MRI to have a better look at your knee.
What is the Treatment for Knee Plica Syndrome?�
Most instances of medial patellar plica syndrome respond well to alternative treatment options, such as chiropractic care, physical therapy or even a physical activity or exercise plan at home. Chiropractic care uses spinal adjustments and manual manipulations to safely and effectively correct a variety of health issues associated with the musculoskeletal and nervous system. Moreover, chiropractic care and physical therapy can include a series of stretches and exercises to help restore strength, mobility, and flexibility to the hamstrings and quadriceps. These stretches and exercises are described below.
Quadriceps Strengthening
The medial plica is attached to the quadriceps, a major muscle on the thighs. An individual with weakened quadriceps has a higher chance of developing knee plica syndrome. You can strengthen your quadriceps by performing the stretches and exercises as follow:
quadriceps sets or muscle tightening
straight leg raises
leg presses
mini-squats
biking, swimming, walking, or use an elliptical machine.
Hamstring Stretching
The hamstrings are the muscles which extend down the back of the thighs, from the pelvis to the shin bone. These help flex the knee. Tight hamstrings place more stress and pressure on the front of the knee, or the plica. A chiropractor or physical therapist will guide the patient through numerous stretches and exercises which may help unwind the nerves. As soon as the patient learns these moves, they may perform them a few times each day to keep the muscles relaxed.
Corticosteroid Injections
Some healthcare professionals may provide corticosteroid injections for the knee if the pain and inflammation causes a restriction in function. Corticosteroid injections can help temporarily reduce painful symptoms, however, it’s essential for the patient to continue with treatment to heal knee plica syndrome. The painful symptoms may return when the corticosteroid burns off if not treated.
Surgery
If chiropractic care, physical therapy, or the treatment described above does not help heal knee plica syndrome, a procedure known as arthroscopic resection may be needed. To perform this process, the doctor will insert a small camera, called an arthroscope, via a tiny cut at the side of the knee. Small surgical instruments are then inserted through a second small cut to take out the plica or correct its position.
After surgery, your doctor will consult with a chiropractor or physical therapist for a rehabilitation program.�Recovering from surgery for knee plica syndrome is dependent upon many factors, including the patient’s overall health and wellness. The patient may recover within a few days in case the knee has been changed. Remember to wair a few weeks before returning to a routine levels of exercise and physical activity.
Living with Knee Plica Syndrome
Plica syndrome is generally easy to treat with chiropractic care, physical therapy,�and other treatment approaches, as described above. Should you need surgery, the approach is minimally invasive and requires less recovery compared to a number of different types of knee surgery.

Many people think of joints, bones, and the, skeletal system when they think of chiropractic, but in fact, the muscles also play an integral part in supporting the body. The muscles are layers and interwoven work to move and stabilize the spine, facilitate the movement of the body�s joints, and aid in respiration. When there is pain within this system, chiropractic can be a very effective treatment. More patients are turning to chiropractic care to treat a variety of painful conditions because it does not use addictive pharmaceuticals with unpleasant side effects; it is completely natural. Chiropractic can also keep patients from requiring surgery in many cases. So when it comes to myofascial pain and trigger points, this form of treatment is often considered optimal.
What is Myofascial Pain?
In simple terms, myofascial pain is simply pain in the muscles. When you break down the word, �myo� means muscle and �fascia� refers to the connective tissue that are interwoven throughout the body.
The pain originates in specific trigger points that are located in the muscles and fascia at various areas of the body. The pain can range in intensity from mild and annoying to severe and debilitating.
What are Trigger Points?
Trigger points are tightened, hypersensitive spots that can be located in any muscle. Different people may have different trigger points. It isn�t like specific lower back pain or neck pain which occur in particular areas of the body. Trigger points can vary from person to person.
When trigger points form, they become nodules or spots that exist in one of the muscle�s taut bands. The patient may experience a variety of symptoms including pain, weakness, burning, tingling, and other symptoms.
What often makes trigger points challenging to locate is that they cause what is known as referred pain. In other words, the person may experience the pain at the exact location of the trigger point, or the pain can be referred to other areas in the body. Referred pain usually has fairly consistent pain patterns so it can be traced to the origin � eventually.
Around 85% of the pain that individuals experience is attributed to myofascial pain. The trigger points determine whether the pain is chronic or acute. It is a condition that is very common.
How do Trigger Points Form?
Trigger points form when the muscle undergoes trauma of some type. The trauma can come from disease, accidents, related work conditions (from persistent, repetitive motion), and sports injuries.
Activities or habits that place a repetitive, long-term strain on the muscles can also cause trigger points. Poor posture, improper ergonomics, and repetitive movements are the most common of these types of activities. Emotional and physical stress are often identified as causes of irritating trigger points.
Benefits of Chiropractic for Myofascial Pain and Trigger Points
Chiropractic care is often a preferred treatment for myofascial pain due to its effectiveness and drug-free approach. Patients who undergo treatment will usually experience a dramatic decrease in their pain level, or it will be eliminated.
They also enjoy increased strength, flexibility, and range of motion. With continued chiropractic care, they will find that they have more endurance for work and recreational activities and even sleep better. It should be noted that sleep disruptions are a common complaint associated with myofascial pain.
Overall, chiropractic can give patients with myofascial pain a better quality of life with decreased incidence of injury. They are often able to lower their pain medication or eliminate it.
Because chiropractic is a whole-body approach, patients learn healthy habits including diet, exercise, and mental wellness. Most of all, they can live with less pain or no pain at all.
