Extensor Mechanism Injuries: Is Return to Sport Feasible?

Abstract

Tendinous extensor mechanism injuries of the knee (i.e., quadriceps and patellar tendon injuries) have become more common in aging athletes as the general population continues to remain active. Structural changes within the quadriceps and patellar tendons can occur with aging, as well as with certain medical comorbidities and medications. There is currently a lack of published data on return to sport after knee extensor mechanism injury in the aging population. Return to some level of sport after tendinous knee extensor mechanism injuries in the aging athlete is possible in the majority of patients, with similar rates of return to sport after quadriceps and patellar tendon injuries.
