Injury may occur secondary to the structure not being able to meet the For example, a runner with knee pain may be engaged in too much activity too . biceps to draw the unsupported proximal part of the fibula posteriorly. reported having a pain-free knee with full range of motion. If a radiograph does not meet these criteria, one should be sus- picious of the to translate the fibular head from anterior to posterior while the knee is at 90° of. Although a posterior cruciate ligament injury generally causes less pain, disability and knee instability than does an ACL tear, it can still.

Functional movement deficits were noted during the squat test and step down test. Outcomes Immediately following intervention, improvements were noted for ankle dorsiflexion, squat test, and step down test. One week following the initial intervention the patient reported she was able to run pain free. Discussion Addressing impairments distant to the site of dysfunction, such as the proximal tibiofibular joint, may be indicated in individuals with lateral knee pain.

A thorough examination of the local structures as well as distant sites may be helpful in the differential diagnosis of lateral knee pain. An adjacent structure which may contribute to lateral knee pain is the proximal tibiofibular joint. During ankle dorsiflexion, torsional stress is placed through the proximal tibiofibular joint, via external rotation and anterior glide of the fibula.

No study has discussed the potential for hypomobility of the proximal tibiofibular joint and the contribution to lower extremity dysfunction. The purpose of this case report was to examine the effect of addressing hypomobility of the proximal tibiofibular joint in an individual with lateral knee pain.

At that time she had been running miles, times a week, for the previous six months. After the onset of knee pain she reduced both distance and frequency to miles, times per week. She recalled no specific trauma or incident that precipitated the pain and reported symptoms only occurred during running and not other activities such as prolonged sitting or stair climbing.

She described pain on the lateral aspect of knee which extended into the region of the proximal tibiofibular joint. Her past medical history included a right lateral ankle sprain, which occurred six years previous. The patient did not seek medical consultation for this injury. She indicated that she had difficulty with walking for 2 to 3 days following the injury and severe ecchymosis resolved within one month. Based on her recall of the injury, the injury was likely be a grade II ankle sprain.

The rest of her medical and orthopedic history was unremarkable. Because this type of joint is less able to rotate to accommodate torsional stresses than a horizontal joint, it may subluxate and dislocate more frequently.

Proximal Tibiofibular Joint Dysfunction

Anterolateral subluxation is the most common subluxation of the PTF joint that occurs during athletic activity, especially actions involving violent twisting motion. This subluxation is best discerned by clinical examination, which will reveal a prominent mass over the lower anterolateral knee joint. When a patient complains of pain and tenderness of the proximal part of the fibula, there may be associated symptoms in the lateral popliteal fossa along the stretched biceps tendon.

In this case, pain can be accentuated by dorsiflexing and everting the foot.

There may also be transient paresthesias along the distribution of the peroneal nerve. Movement of the knee is usually painless, with a deficit in range a few degrees short of full extension.

The biceps tendon may be in a muscular spasm or may be palpated as hypertonic. Upon observation, the fibular head will appear as a prominent lateral mass. A typical mechanism of anterolateral subluxation may be the following: Tibiofibular subluxations occur under traumatic conditions such as twisting athletic injuries, a slipping injury in which the patient lands with their knee flexed under their body, or parachute landings.

What causes pain behind the knee?

Anterolateral subluxations can be sustained from a wide variety of sports activities such as football, soccer, rugby, wrestling, gymnastics, judo, broad jumping and skiing Posterolateral subluxations are usually associated with violent trauma to the knee, with the proximal part of the fibula being pushed posteriorly and medially.

Severe disruption of the anterior and posterior capsular ligaments of the tibiofibular joint, probably with a significant tear of part of the fibular collateral ligament, allows the biceps to draw the unsupported proximal part of the fibula posteriorly. This type of dislocation is invariably associated with a fracture of the tibial shaft. The literature describes a variety of proximal fibula subluxations. I have provided a complete list of them with a description of the extra vertebral adjustment for each as follows: Superior Fibula Subluxation Subluxation: A superior fibula subluxation often allows eversion sprain of the ankle.

Typical features include tenderness about the fibular collateral ligament due to jamming, restricted inferior fibula joint play, and possibly a slight foot-drop sign. Place the patient supine with the knee extended and hip flexed at about 45 degrees. Stand at the end of the table with the patient's foot placed on the anterior aspect of your thigh.

Grasp the patient's ankle with your lateral hand, and take a web or capitate contact at the proximal aspect of the lateral malleolus. With your medial hand, overlap the wrist of your contact hand for stability.

Apply traction and simultaneously make a short, inferiorly directed thrust to correct the malposition. Inferior Fibula Subluxation Subluxation: An inferior fibula subluxation can be the result of inversion ankle sprain and is often associated with tenderness about the collateral ligament of the fibula and restricted superior fibula joint play.

Place the patient in the lateral recumbent position with the affected side upward and the medial aspect of the affected foot resting relaxed on the table.

Stand at the foot of the table in line with the longitudinal axis of the patient's affected leg. Apply a capitate contact with your medial hand against the inferior aspect of the lateral malleolus, with your lateral hand grasping your contact wrist for stability.

Apply pressure and simultaneously make a short thrust directed superiorly along the vertical axis of the fibula to correct the malposition. An anterolateral fibula subluxation is often the result of lateral hamstring strain, inversion ankle sprain or trauma to the posterolateral aspect of the knee.

It is characterized by lateral hamstring tendon tenderness, genu varum, excessive ankle pronation, and restricted posteromedial fibula motion.

Place the patient prone with the involved knee flexed.

Squat at the end of the table facing the patient so that the patient's leg can rest on your shoulder for stability. Grasp the involved leg and interlace your fingers around the posterior aspect of the patient's leg proximally. Direct a pisiform contact with your cephalad hand against the anterolateral aspect of the fibular head.

Apply traction and simultaneously rotate the fibula posteromedially to correct the malposition. Posteromedial Fibula Subluxation Subluxation: A posteromedial subluxation of the fibula often follows inversion ankle sprain, violent hamstring pull, trauma to the anterolateral knee and genu valgum. Place the patient prone with the involved leg fixed. Squat at the end of the table facing the patient so that the patient's leg rests on your shoulder for stability. Apply a specific pisiform contact with your lateral hand against the medial aspect of the involved fibular head.

Apply traction, and simultaneously rotate the fibula impulsively anterolaterally to correct the malposition. Postero-Inferior Fibula Subluxation Subluxation: The typical physical features of a postero-inferior subluxation of the fibula include pain at the fibula head, lateral collateral ligament pain at the ankle, lateral hamstring complaints, and restricted anterosuperior fibula joint play.
