Patellofemoral pain is one of the leading causes of knee pain in athletes. The many causes of patellofemoral pain make diagnosis unpredictable and examination and treatment difficult. This clinical commentary discusses a detailed physical examination routine for the patient with patellofemoral pain. Critically listening and obtaining a detailed medical history followed by a clearly structured physical examination will allow the physical therapist to diagnose most forms of patellofemoral pain.

This clinical commentary goes one step further by suggesting an examination scheme and order in which it should be performed during the examination process. This step-by-step guide will be helpful for the student or novice therapist and serve as review for those that are already well versed in patellofemoral examination.

Patellofemoral pain syndrome PFPS is considered to be one of the most common medical diagnoses made in outpatient orthopedics in patients complaining of knee pain. In order to determine what form of intervention is needed in a patient with knee pain, the clinician must initially perform an accurate, comprehensive, yet concise physical examination. Examination findings are not always consistent, nor directly related to symptoms. Additionally, there is no single definitive clinical test used to diagnose patellofemoral pain syndrome.

Clinical experience examining and treating many patients with knee conditions is helpful in making a correct diagnosis.

Following an examination scheme consistently will provide the clinician with a good foundation to decipher what findings may be considered normal and abnormal. This systematic, complete, and detailed approach to examination will allow the clinician to identify all contributing factors, ultimately leading to optimal treatment approaches by addressing all potential causative factors, which should result in a more compliant patient and better outcomes.

The cornerstone of any examination is the medical history. If the clinician listens closely enough, and asks the appropriate questions during any medical history the patient will often describe what their diagnosis is. If indicated, it is important to understand that it is always prudent to refer back to the original referral source or to another medical provider in order to rule out any suspicious symptoms that are out of the ordinary or may not be attributable to musculoskeletal factors.

The patient's activities of daily living, vocational activities, recreational or sporting activities are also important to understand because they may contribute to the patient's symptoms. Oftentimes, changing or modifying the cause of the problem may help resolve some of the symptoms. PFPS is in many instances a nonspecific complaint that can be traced to or associated with multiple conditions.

These include compressive issues, instability, biomechanical dysfunction, direct patellar trauma, soft tissue lesions, overuse syndromes, osteochondritis dissecans, and neurologic disorders.

Going to a movie, sitting in a car or plane during long trips often aggravate the symptoms.In general, patients do not have problems with medial patellar instability. However, in some patients who have had a lateral release, they will have symptoms of the patella subluxing medially.

This can occur in patients with an extensive lateral release. This can be one of the most difficult problems to diagnose in orthopaedics because it is not well described. I have seen many patients who have seen greater than five physicians who have undergone trials of taping, physical therapy, bracing and other treatment means without a true diagnosis of their condition.

In addition, many of the patients feel as if there patellar subluxes laterally when it is actually subluxing medially. This taping technique is when the patellar is held laterally to attempt to prevent it from subluxing medially. The medial patellar apprehension test is performed by placing the knee in full extension and applying a medial translation force to the patella.

The knee is then flexed. If the patella does significantly sublux medially, the patient will note the feeling of apprehension and the patella can be found to reduce back into the bony confines of the trochlear groove with further knee flexion. As always with a knee exam, the contralateral patella should be assessed to determine the amount of normal medial patellar subluxation in a particular patient.

Knee Pain Reduced in 30 Seconds / Patella Release Technique -- Dr Mandell

Patellar tracking disorder means that the kneecap patella shifts out of place as the leg bends or straightens. In most cases, the kneecap shifts too far toward the outside of the leg. In a few people, it shifts toward the inside. Your knee joint is a complex hinge that joins the two bones of the lower leg with the thighbone. You are more likely to have patellar tracking disorder if you have any of the above problems and you are overweight, run, or play sports that require repeated jumping, knee bending, or squatting.

If your kneecap is completely dislocated, you may have severe pain and swelling.

Your knee may look like a bone is out of place. And you may not be able to bend or straighten the knee. If you have these symptoms, be sure to see your doctor. A dislocated kneecap needs to be put back in place by a doctor right away.

It can be hard to tell the difference between patellar tracking disorder and some other knee problems. To find out what problem you have, your doctor will:. You may have an X-ray so your doctor can check the position and condition of your knee bones. If more information is needed, you may have an MRI.

Patellar tracking disorder can be a frustrating problem, but be patient. Most people feel better after a few months of treatment. As a rule, the longer you have had this problem, the longer it will take to get better.

Treatment of patellar tracking disorder has two goals: to reduce your pain and to strengthen the muscles around your kneecap to help it stay in place.

If you don't have severe pain or other signs of a dislocated kneecap, you can try home treatment for a week or two to see if it will reduce your pain. As your knee pain starts to decrease, do exercises to increase strength and flexibility in your leg and hip. Your doctor or a physical therapist can help you plan an exercise program that fits your condition. You will probably start with one or two exercises and add others over time.

Make sure to closely follow the instructions you're given.

Thanks for the question about the knee-cap exercise. Easier for me to make a judgment call when I have a client in front of me, know their full health history, and can see them move.

When in doubt, or if any exercise you are doing is causing pain — I would immediately stop doing the exercise. Perhaps there are modifications, or other adjustments that need to be made. If you deem it is safe for you to continue this exercise, you might work in a smaller range of motion to move the kneecap to start and see if you can do the exercise and avoid the crunching that you are talking about.

Also, the knee cap should be gliding evenly, straight up the middle. Now test the other leg. Is there a difference in the sounds that your knees make?

Do they both crunch, or is one worse than the other? Does your noisy knee correlate to any knee pain or problems you have experienced? Tracking issues unfortunately are common.

Some folks can get away with this misalignment for a lifetime and have relatively few knee problems. Other folks end up with multiple knee surgeries, and knee replacements because they never took care to improve their posture, strength, flexibility and change bad movement patterns.

I would recommend that you consider seeing your primary care doctor, a sports medicine physician, or get a referral to a physical therapist to rule out any serious knee issuesand ask them about the exercises you are doing, if they are OK for you, or what other exercises you can be doing to safely improve things.

If there is a Pilates studio, or well-qualified Pilates teacher in your area — even if you only take a couple of private sessions to have someone help you improve your exercise technique and body awareness for an at-home program it would be a good investment. Used by Permission.

Reasons Why You May Experience Knee Cap Pain: Sometimes if part of the quadriceps muscle either inner or outer portion pulls stronger it can pull the kneecap to either the inside or outside of the thigh, which can cause the grinding and miss-aligned tracking issue. Weak inner thighs adductorsweak outer thighs abductorsand weak Glutes affect the stability of the knee when standing on one leg or bending and straightening the knees.

If the knee locks when you are standing or doing any type of exercise, the hamstrings are weak, and locking jams the kneecap against the leg bones in not a good way! Have you tried the Knee Cap Dance Exercise yet?The clinical evaluation of the knee is a fundamental tool to correctly address diagnosis and treatment, and should never be replaced by the findings retrieved by the imaging studies carried on the patient.

Every surgeon has his own series of exams with whom he is more confident and on whom he relies on for diagnosis. This review analyses the most commonly used tests and signs for knee examination, outlining the correct way to perform the test, the correct interpretation of a positive test and the best management for evaluating an injured knee both in the acute and delayed timing.

The introduction of highly effective imaging tools like Computed Tomography and Magnetic Resonance in the clinical practice in Orthopaedics and Traumatology has stolen the central role of clinical evaluation, so that nowadays there's a common feeling, between patients but also between surgeons, that the diagnosis of a thorn meniscus or a ruptured ACL has to be ruled out only on the basis of an imaging study.

In all cases, the clinical evaluation should be introduced by a careful interview of the patient, in order to address the subsequent exam to the affected area of the knee, and to choose the correct series of tests and signs. Extensor mechanism pathology is often related to a chronic, repetitive trauma.

Nevertheless, recent injuries should be enquired, as anterior knee pain can be associated to a recent patellar subluxation or dislocation, or to ruptured patellar or quadriceps tendons, particularly in older patients.

Anterior pain during activity and at rest is mostly associated with chondral lesions, while pain associated with prolonged flexion can be raised by a slight instability or malalignement. Meniscal lesions are almost always consequence of a single trauma, but chronic lesions and degenerative tears of the menisci as well as chondral defects secondary to overuse should not be forgotten.

The interview should be focused on the mechanism of injury direct trauma, sprain, complex trauma and on the pre-existing condition of the knee e. Most patients do not report a real trauma, but rather an acute pain occurred after a weight-bearing twist on the knee or a knee flexion. Locking of the knee is usually associated with bucket handle tears of the meniscus, and must be carefully inquired.

An haemorrhage around the posterior capsule and medial collateral ligament, with subsequent hamstring spasm can mimic a locking. Snaps, clicks, catches or jerks can be reported by the patients and the examiner should try to reproduce them with the manipulative manoeuvres. Painful giving away of the knee is a common symptom, and is often reported as caused associated to rotatory movements and often associated with a feeling of "the joint jumping out of place".

This symptom is non-specific and also reported in case of loose bodies, patellar chondromalacia, instability, quadriceps weakness. In case of instability, the onset of the lesion can most of the times be related to a single injury, and the patient usually remembers it. However, it is often difficult to recall the exact mechanism of injury, and the patient should be forced in trying to reproduce the "twist" or impact sustained by the knee at the time of the injury: this can strongly help in estimating the anatomic structure s involved in the lesion.

The series of the most known exams, signs and tests used for each of the three aspects will be here discussed. The Q-angle is the intersection between a line drawn from the anterior superior iliac spine to the center of the patella and a line drawn from the center of the tibial tubercle to the center of the patella.If you have knee pain, your physical therapist or doctor may perform knee special tests to determine if a ligament sprain may be causing your problem.

Knee special tests stress various ligaments in your knee, assessing their integrity to help guide your knee pain diagnosis and, ultimately, your treatment. The knee joint is stabilized by four important ligaments. Each separate ligament prevents excessive motion of the knee. The anterior cruciate ligament prevents excessive anterior glide of your shin under your thigh bone. The posterior cruciate ligament prevents excessive posterior motion of your shin below your femur.

Your medial collateral ligament prevents excessive abduction of the tibia and guards an excessive force coming from the outside area of your knee. Your lateral collateral ligament prevents excessive adduction of the tibia and guards against an excessive force coming from the inside aspect of your knee.

When damaged, your knee becomes unstable in the direction that the injured ligament stabilized. If you suspect that you have damaged a knee ligament, you must check in with your doctor to get an accurate picture of your condition and to start on the correct treatment.

You may benefit from a visit with a physical therapist to assess your knee. He or she may perform knee special tests to check the integrity of your knee ligaments.

There are four special tests each to evaluate the four ligaments of your knee. Learn the names of these tests, the ligaments they evaluate, and how to perform them. Remember, if you have a knee condition, check in with your doctor before performing these knee special tests. The anterior drawer test is used to assess the integrity of your anterior cruciate ligament ACL.

This ligament prevents forward slippage of your shin bone underneath your thigh bone. The test is performed by lying down on your back with your knee bent. Another person grasps your tibia just behind your knee and gently pulls forward. Excessive motion of your tibia underneath your femur indicates a positive test and an ACL tear may be suspected.

The posterior drawer test evaluates the posterior cruciate ligament PCL. This ligament prevents your shin bone from slipping backward underneath your thigh bone. To perform this test, place the knee in ninety degrees of flexion with the patient lying supine and the foot stabilized on the table. Grasp the anterior aspect of the tibia over the tibial tuberosity and push forward displacing the tibia posteriorly with a steady force.

If the tibia moves posteriorly more than normal compare with the uninjured leg the test is positive.
