The term includes patellar tendinopathy and quadriceps tendinopathy. Although the patellar and quadriceps tendons work in tandem as part of the extensor mechanism of the knee, they have distinct anatomy and functional roles. As a result, there are probable differences in risk factors, etiology, and response to treatment. It is time to clinically separate patellar tendinopathy and quadriceps tendinopathy and design more specific rehabilitation programs. In this Viewpoint, the authors will (1) provide a rationale for distinguishing the 2 clinical entities\u2014patellar tendinopathy and quadriceps tendinopathy\u2014for treatment decision making, and (2) identify areas of research priority in quadriceps tendinopathy.
