A thorough examination of the entire lower extremity is needed to identify relevant deficits at the hip, knee, and ankle/foot region. Often malalignment of the foot, heel, or tibia can place excess stress on the knee extensor tendons increasing the risk of tendinopathy. [14] Larsen E, Lund PM.

Initially, the physical therapist must work with physicians to implement a nonoperative regimen consisting of therapy with isometric or eccentric exercises as the mainstay treatment. In a level 2 study, at 12 weeks, patients undergoing an eccentric exercise program showed significant improvement compared with those undergoing a concentric exercise program. [10]As the treatment progresses, plyometrics and sport-specific training is required to return the athlete to sport at the highest level Burks RT, Edelson RH.

Most patients with jumper's knee are managed through medical and rehabilitative treatment in the initial stages of the disease. [22]Early recognition and diagnosis of jumper's knee are vital as they can have a progressive course. Although non-steroidal anti-inflammatory drugs were used traditionally, these have recently become less judicious as more physicians have come to realize that the disease is not inflammatory. Hence, NSAIDs may not provide a significant long-term benefit in tendinopathy. [4]Corticosteroid injections are contraindicated as they bear a risk of patellar tendon rupture. Weiler JM.
