The tendon is palpated most easily when the lateral ankle of the affected leg rests on the opposite knee. The lateral collateral ligament is most prominent in this position and the popliteus is palpated just anterior to it and above the joint line. Iliotibial band syndrome Pain localized to lateral femoral condyle With patient supine and knee flexed to 90 degrees, have patient extend knee while exerting pressure over the lateral femoral condyle. At 30 degrees of flexion the patient will experience pain as the iliotibial band crosses the epicondyle. Localized tenderness approximately 6 cm proximal to the Achilles insertion on the heel Pain with resisted plantar flexion of the ankle Crepitus may be palpable with severe cases.
Overuse is the most common etiology.
Tendinopathy can occur within a few days or weeks or months following completion of a course of quinolones. Tendon rupture can occur without a history of specific trauma. Pathophysiology is unknown. Unlike other etiologies, bilateral tendinitis is common. Radiographs may be indicated if a history of trauma is present, but they usually are negative with tendonitis.
