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.
Talk to your healthcare professional to determine the best treatment choice for your knee plica syndrome. The scope of our information is limited to chiropractic and spinal health issues. To discuss the subject matter, please feel free to ask Dr. Jimenez or contact us at�915-850-0900�.

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.
EXTRA EXTRA | IMPORTANT TOPIC: El Paso, TX Chiropractor Recommended
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.
Chondromalacia patellae, also referred to as runner’s knee, is a health issue in which the cartilage beneath the patella,�or kneecap, becomes soft�and ultimately degenerates. This problem is prevalent among young athletes,�however, it may also develop in older adults who suffer from arthritis of the knee.
Sports injuries like chondromalacia patellae are frequently regarded as an overuse injury. Taking some time off from participating in physical activities and exercise may produce superior outcomes. In the instance that the individual’s health issues are due to improper knee alignment, rest may not offer pain relief. Symptoms of runner’s knee include knee pain and grinding sensations.
What Causes Chondromalacia Patellae?
The kneecap,�or the patella, is generally found through the front of the knee joint. If you bend your knee, the rear end of your kneecap slips over the cartilage of your femur, or thigh bone, at the knee. Complex soft tissues, such as tendons and ligaments, connect the kneecap to the shinbone and thigh muscle. Chondromalacia patellae�can commonly occur when any of these structures fail to move accordingly, causing the kneecap to rub against the�thigh bone. Poor kneecap motion may result from:
Misalignment due to a congenital health issue
Weakened hamstrings and quadriceps, or the muscles of the thighs
Muscle imbalance between the adductors and abductors, the muscles on the inside and outside of the thighs
Continuous pressure to the knee joints from certain physical activities and exercise like running, skiing, or jumping
a direct blow or injury for a kneecap
Who is at Risk for Chondromalacia Patellae?
Below is an assortment of factors which may increase an individual’s chance for developing chondromalacia patellae.
Age
Adolescents and young adults have the highest risk for this health issue. During growth spurts, bones and muscles can often grow too rapidly, causing short-term muscle and bone imbalances in the human body.
Gender
Females are more likely than males to develop runner’s knee, because women generally possess less muscle mass than men. This may result in abnormal knee placement, and more lateral pressure on the kneecap.
Flat Feet
Individuals who have flat feet can add more strain to the knee joints as compared to individuals who have higher arches.
Past Injury
Previous injuries to the kneecap, including a dislocation, can raise the chance of developing chondromalacia patellae.
Increased Physical Activity
Increased levels of physical activities and exercise can place pressure on the knee joints, which may raise the risk for knee issues.
Arthritis
Runner’s knee may also be an indication of arthritis, a well-known problem causing pain and inflammation to the tissue and joint. Swelling can prevent the proper function of the knee and its complex structures.
What are the Symptoms of Chondromalacia Patellae?
Chondromalacia patellae will generally present as pain in the knee, called patellofemoral pain, accompanied by sensations of cracking or grinding when extending or bending the knee. Pain may worsen after sitting for an extended period of time or through physical activities and exercises that apply intense pressure for your knees, like standing. It’s essential for the individual to seek immediate medical attention if the symptoms of chondromalacia patellae, or runner’s knee, do not resolve on their own.
Diagnosis and Chondromalacia Patellae Grading
A healthcare professional will search for areas of pain and inflammation on the knee. They might also look at the way the kneecap aligns with the thigh bone. A misalignment may indicate the presence of chondromalacia patellae. The doctor may also perform a series of evaluations to ascertain the presence of this health issue.
The healthcare professional may also ask for any of the following tests to help diagnose chondromalacia patellae, including:�x-rays to show bone damage or misalignments or arthritis; magnetic resonance imaging, or MRI, to see cartilage wear and tear; and�arthroscopic examination, a minimally invasive procedure which involves inserting an endoscope and camera inside the knee joint.
Grading
There are four levels of chondromalacia patellae, ranging from grade 1 to 4, which characterize the level of the patient’s runner’s knee. Grade 1 is considered mild while grade�4 is considered severe.
Grade 1 indicates the softening of the cartilage in the knee region.
Grade 2 suggests a softening of the cartilage followed by abnormal surface features, the start of degeneration.
Grade 3 reveals the thinning of the cartilage together with active degeneration of the complex soft tissues of the knee.
Grade 4, or the most severe grade, demonstrates exposure of the bone through a substantial part of the cartilage Bone exposure means that bone-to-bone rubbing is most likely happening in the knee.
What is the Treatment for Chondromalacia Patellae?
The goal of treatment for chondromalacia patellae is to first decrease the strain being placed on the kneecap, or patella, and the femur, or thigh bone. Rest and the use of ice and heat agains the affected knee joint is generally the first line of treatment. The cartilage damage associated with runner’s knee may often repair itself with these remedies along.
Moreover, the healthcare professional may prescribe anti-inflammatory drugs and/or medications, such as ibuprofen, to decrease pain and inflammation around the knee joint. When tenderness, swelling, and pain persist, the following treatment options could be explored. As mentioned above, individuals should seek immediate medical attention if symptoms persist.�
Chiropractic Care
Chiropractic care is a safe and effective, alternative treatment option which focuses on the diagnosis, treatment, and prevention of a variety of injuries and/or conditions associated with the musculoskeletal and nervous system, including chondromalacia patellae. Occasionally,�knee pain may originate due to spinal misalignments or subluxations. A doctor of chiropractic, or chiropractor, will use spinal adjustments and manual manipulations to carefully restore the natural integrity of the spine.�
Furthermore, a chiropractor may also recommend a series of lifestyle modifications, including nutritional advice and a physical activity or exercise guide to help ease symptoms associated with chondromalacia patellae. Rehabilitation may also focus on�strengthening the quadriceps, hamstrings, adductors, and abductors to improve muscular strength, flexibility, and mobility. The purpos of muscle balance is also to assist in preventing knee misalignment, among other complications.
Surgery
Arthroscopic surgery might be required to inspect the joint and ascertain whether there is a misalignment of the knee. This operation involves inserting a camera in the knee joint through a very small incision. A surgical procedure can repair the issue. One�common process is a lateral release. This surgery involves cutting a number of the ligaments to release tension and permit for more movement. Additional surgery may entail implanting the back of the kneecap, inserting a cartilage graft, or transferring the thigh muscle.
�
Chondromalacia patellae is characterized as the inflammation of the underside of the patella, or kneecap, caused by the softening of the cartilage surrounding the soft tissues of the knee joint. This well-known health issue is generally caused due to sports injuries in young athletes, although chondromalacia patellae may also occur in older adults with arthritis in the knee. Chiropractic care can help restore strength and balance to the knee joint and its surrounding soft tissues.
Dr. Alex Jimenez D.C., C.C.S.T. Insight
How to Prevent Chondromalacia Patellae
A patient can ultimately lower their chance of developing runner’s knee, or chondromalacia patellae, by:�
Avoiding repeated stress on the knees. In case the individual needs to spend time on their knees, they could wear kneepads.
Produce muscle balance by strengthening the quadriceps, hamstrings, abductors, and adductors.
Wear shoe inserts that correct flat feet. This may reduce the amount of pressure being placed on the knees to realign the kneecap, or patella.
Keeping a healthy body weight can also help prevent chondromalacia patellae. Following the nutritional advice and guidance from a healthcare profesional can help promote a healthy body weight.

Result from valgus or varus stress with or w/o axial loading
Associated with periarticular soft tissues injury
High-stress injury m/c due to jumps falls and axial loading, often with the splitting of the tibial plateau. Men>women. Patients are in their 30s
Low impact or no trauma in patients with osteoporosis d/t insufficiency fractures
Impaction injury is more common with depression of tibial plateau. Women>men. Patients are in their 70s
Lateral Tibial Plateau Fractures More Common
Functional anatomy plays a significant role
60% of weight bearing is by the medial plateau
The medial plateau is more concave
Lateral plateau is slightly higher and more convex. Valgus stress impacts lateral plateau.
Tibial plateau fractures considered intra-articular and prone to delayed healing, non-union, meniscal injury (m/c lateral) ACL tear, secondary OA. Other complications: compartment syndrome, vascular injury.
Management: operative in many cases especially if >3-mm step-off at the plateau
If medial plateau or bicondylar Fxs present, ORIF will be required.
Imaging Plays A Crucial Role
Begins with x-radiography. X-radiography may not reveal the complexity and extent of this injury.
CT scanning w/o contrast will further delineate fracture complexity and pre-operative planning
MR imaging may be considered to evaluate for internal derangement: meniscal, ACL injuries.
Shatzke classification may help to evaluate the complexity of this injury
Key Diagnostic Sign
AP and lateral horizontal beam (cross table) left knee radiograph. Note subtle depression of the lateral plateau manifested by the lateral plateau appearing at the same level or lower as the medial. A critical diagnostic sign is the presence of fat-blood-interphase or FBI sign on cross-table lateral (above arrow) indicating intra-articular knee fracture
Lipohemarthorosis aka FBI Sign
Can be detected by radiography, CT or MR imaging
FBI sign is a reliable secondary radiographic sign of intra-articular knee fractures, regardless of how small they are
Mechanism: fracture results with acute hemarthrosis
Hemarthrosis will also occur w/o Fx. However, Fx will result with a fatty marrow being released into the joint cavity. Fat is a less dense medium (lighter) and will appear on the top of the hemorrhage if the patient is held in the supine position for 5-10-minutes before the cross-table radiograph is taken
FBI sign confirms the intra-articular Fx.
ACL/PCL, meniscal tears will not result in FBI sign
Lateral Tibial Plateau Fx
Lateral tibial plateau Fx that was managed operatively
Most common complication: premature secondary OA
More complex injuries may result in more extensive operative care
Knee Internal Derangement
Acute or chronic injuries of meniscal fibrocartilages and ligamentous restraints
Tears of the ACL and posterior horn of the medial meniscus are the most common
Acute ACL tears, however, often result with a lateral meniscus tear
Acute ACL tear may occur as a combined injury of the ACL, MCL, and medial meniscus
Functional anatomy: ACL prevents anterior displacement of the tibia and secondary varus stress
MCL functions together with ACL in resisting external rotation of the tibia especially when the foot is planted (closed chain position)
MCL is firmly attached to the medial meniscus, explaining the classic triad of ACL, MCL and medial meniscal tear (O’Donahue terrible triad)
Cruciate ligaments (ACL/PCL) are intra-articular but extra-synovial. Less likely to be torn in closed pack position (full extension). When all articular facets of tibia and femur are in full contact, the ACL/PCL are at least tension and stable
When the knee is flexed 20-30-degrees or more ACL is taut and remains unstable
ACL is a significant mechanoreceptor that feeds the info to CNS about the joint position. Thus the majority of previous ACL tears will lead to some degree of knee instability
Functional Anatomy of ACL
Diagnosis of ACL Tear
Diagnosis of ACL tear requires MR imaging
Concerns exist of not only ligamentous injuries but injuries to the articular cartilage and menisci.
Most vendors will perform at least: one T1 WI in coronal or sagittal planes. Sagittal and coronal Proton-density slices to evaluate cartilaginous structures. Fast spin-echo sagittal, axial and coronal T2 fat-saturated or sagittal and coronal STIR images are crucial to demonstrate edema within the substance of knee ligaments
ACL is aligned along the Blumensaat line or oblique line corresponding the intercondylar roof of Femoral condyles. Lack of such alignment by the ACL is significant for ACL tear
Imaging Dx of Internal Derangement
MRI shows 78-100% sensitivity and 78-100% specificity
Primary signs of ACL tear: non-visualization of ACL (above green arrow), loss of its axis along the Blumensaat line (above triangle heads), wavy appearance and substance tear (above white arrow) or edema and cloud-like indistinctness (above yellow arrow)
Reliable Secondary Signs of ACL Tear
May be observed on the radiographs and MRI
Segond avulsion fracture (80% specificity for ACL tear) (next slide)
Deep femoral notch sign indicating osteochondral fracture (above bottom images) and
Pivot -shift bone marrow edema in the posterolateral tibial condyle d/t external rotation and often valgus impact by the lateral femoral condyles (above top image)
Segond Fracture (Avulsion by ITB)
Segond fracture at Gerdy’s tubercle. A vital sign of the ACL tear seen on both radiographs and MRI
Management of ACL Tears
In acute cases, usually operative using cadaveric or autograft (patella ligament or hamstring) ACL reconstruction
Complications: graft tear, instability and premature DJD, joint stiffness d/t lack of postoperative rehab or gaft shortening. More rare, infection, a formation of intraosseous synovial cysts, etc.
Have you ever had a pain in the neck? And your kids or significant other don’t count. If you’ve ever had a stiff, sore neck, then you’ve more than likely experienced cervicalgia. You’re not alone. The American Osteopathic Association estimates that more than 25% of Americans have experienced or chronically experience neck pain. Neck pain is one of the primary causes of chronic pain, ranking number three behind knee pain (number two) and back pain (number one). Chronic pain affects around 65% of people in the United States, ranging in age 18 to 34. They either have experienced it firsthand or care for someone who has recently experienced it. That number increases as the population ages.
It is also worth noting that most doctors prescribe pain medications, but more than 33% of patients with chronic pain won’t take them because they are afraid of becoming addicted.
What is Cervicalgia?
Cervicalgia is a blanket term used to describe neck pain. It can range from a simple crick in the neck to severe pain that prevents you from turning your head.
Knowing the term for the pain, though, does not help when it comes to treatment because treatment lies in the cause of the pain. It can become quite complex because there are so many causes for the pain. Sometimes the cause itself must be eliminated before the treatments for the pain can be effective.
What are the Causes of Cervicalgia?
The causes of cervicalgia are vast and varied. A patient who sits at their desk for too long or sleeps in a poor position can develop neck pain.
Injuries such as sports injuries and whiplash fall at the more severe end of the spectrum. Even simple gravity can be a culprit.
The human head can weigh as much as 10 pounds, sometimes even more, and the neck is tasked with keeping it upright. Just the action of fighting gravity and keeping the head erect for long periods of time (like all day) can cause the neck muscles to become strained and fatigued. This can also cause neck injuries to heal slower because the neck is almost always in use and under consistent stress.
How is Cervicalgia Treated?
Treatment for cervicalgia depends on both the symptoms and the cause. If you have been injured, you should immediately seek medical attention to assess the injury’s severity.
You can apply ice to help reduce inflammation and swelling, but do not delay a medical evaluation. Some neck injuries can be severe, causing severe conditions, including paralysis.
After an assessment, your doctor may prescribe medication such as anti-inflammatories and stronger painkillers. A cervical collar may also be recommended since it allows the neck to rest, which will promote healing.
If the pain is caused by other reasons such as stress, poor posture, or sleeping on the wrong pillow (in other words, you have a crick in your neck), you can use an over-the-counter anti-inflammatory medication, and using a heating pad will help. Massage is also effective.
However, prevention is the best cure. When you know what is causing your cervicalgia, you can take steps to prevent it. Chiropractic can help both in prevent cervicalgia and in treating it.
Chiropractic for Cervicalgia
Chiropractic treatment can help relieve cervicalgia pain for many of the causes, including injury, stress, and misalignment. Depending on the cause, the chiropractor will use specific techniques to treat the root of the problem.
They will bring the body back into alignment, which also helps to prevent the pain of cervicalgia. The most attractive aspect is that it allows for pain management without the use of any medications.
When you get regular chiropractic care, you can reduce your chances of experiencing pain in your neck and back. That is why so many people are choosing chiropractic care for their neck and back pain instead of turning to traditional medicine because it works.
Osgood-Schlatter disease is a common cause of knee pain in growing adolescents. It is characterized by the inflammation of the site below the knee where the tendon from the kneecap, or the patellar tendon, attaches to the shinbone, or tibia. Osgood-Schlatter disease occurs during growth spurts when muscles, bones, tendons, and other tissues shift�rapidly.
Physical activities can place additional stress on the bones, muscles, tendons and other complex structures of young athletes. Children and adolescents who participate in running and jumping sports have a higher chance of developing this condition. However, less active children and adolescents may also experience this well-known health issue.
In the majority of instances, Osgood-Schlatter disease will resolve on its own and the pain can be managed with over-the-counter drugs and/or medications. Stretches and exercises can also help improve strength, flexibility and mobility. Alternative treatment options, such as chiropractic care, can also help relieve pain and restore the patient’s�well-being.
Osgood-Schlatter Disease Explained
The bones of children and adolescents have a special area where the bone grows, known as the growth plate. Growth plates are made up of cartilage, which harden into solid bone, when a child or adolescent is fully grown.
Some growth plates function as attachment sites for tendons, the strong soft tissues which connect muscles to bones. A bump, known as the tubercle, covers the growth plate at the end of the tibia. The set of muscles in the front of the thigh, or the quadriceps, then attaches to the tibial tubercle.
When a child or adolescent participates in physical activities, the quadriceps muscles pull the patellar tendon which then pulls the tibial tubercle. In some children and adolescents, this traction on the tubercle can cause pain and inflammation in the growth plate. The prominence, or bulge, of the tubercle may become pronounced as a result of this problem.
Osgood-Schlatter Disease Symptoms
Painful symptoms associated with Osgood-Schlatter disease are often brought on by running, jumping, and other sports-related pursuits. In some cases, both the knees have symptoms, although one knee might be worse. Common symptoms of Osgood-Schlatter disease also include:
Knee pain and tenderness in the tibial tubercle
Swelling in the tibial tubercle
Tight muscles at the front or back of the thigh
Osgood-Schlatter disease is the inflammation of the bone, cartilage and/or tendon at the top of the shinbone, or tibia, where the tendon attaches to the kneecap, or patella. Osgood-Schlatter disease is considered to be an overuse injury rather than a disorder or condition. Osgood-Schlatter disease is one of the most common causes of knee pain in children and adolescents. Although it can be very painful, the health issue generally goes away on its own within 12 to 24 months.

Osgood-Schlatter Disease Diagnosis
Throughout the consultation, the healthcare professional will discuss the children or adolescent’s symptoms regarding their overall health and wellness. They will then conduct a comprehensive evaluation of the knee. This will consist of applying pressure to the tibial tubercle, which should be painful for a patient with Osgood-Schlatter disease. Additionally, the doctor may also ask the child or adolescent to walk, run, jump, or kneel to see whether symptoms are brought on by the movements. Furthermore, the healthcare professional may also order an x-ray of the patienet’s knee to help support their diagnosis or to rule out any other health issues.
Osgood-Schlatter Disease Treatment
Treatment for Osgood-Schlatter disease focuses on reducing pain and inflammation. This generally requires limiting physical activities until symptoms improve. Sometimes, rest may be necessary for many months, followed by treatment and rehabilitation program. However, participation may be safe to continue if the patient experiences no painful symptoms. The doctor may recommend additional treatment, including:
Stretchex�and exercises. Stretches and exercises for the front and back of the thigh, or the quadriceps and the hamstring muscles, can help alleviate pain and prevent the disease from returning.
Non-steroidal anti-inflammatory drugs. Medications like ibuprofen and naproxen can also help reduce pain and inflammation.
Most symptoms will completely vanish when a child completes the adolescent growth spurt, around age 14 for girls and age 16 for boys. Because of this, surgery is often not recommended, although the prominence of the�tubercle will remain.�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.
