patellofemoral instability


patellofemoral instability

Laxity and/or tightness of the patellar restraints that results in abnormal tracking of the patella within the femoral trochlea. Patellofemoral instability causes pain during activity and may predispose the patient to recurring patellar subluxation or dislocation and to subsequently present with the clinical signs and symptoms of chondromalacia.

Treatment

Nonoperative treatment consists of strengthening weak muscles and/or stretching the tight soft tissue that leads to abnormal patellar tracking. Surgical intervention may be required to release overly taut tissue and shave the articular cartilage associated with chondromalacia.
