Also known as jumpers\u2019 knee, it is commonly seen in high\u2010level basketball players. Typically, athletes continue to play with symptoms, which can be aggravated and progress to partial patellar tendon tears. When partial patellar tendon tears occur, prolonged recovery and decreased performance is commonly seen. The pathology and treatment can be frustrating for both the athlete and medical provider. Patellar tendinopathy typically does not involve inflammation but rather microinjury to the tendon fibers, which leads to mucoid degeneration, necrosis, and loss of transitional fibrocartilage. When partial tendon tears do occur, the typical location is posteromedially adjacent to the patella. Treatment involves a stepwise approach starting with nonoperative means, including activity modification, nonsteroidal anti\u2010inflammatories, and physical therapy focused on eccentrics. Extracorporeal shock wave treatments and injections with platelet\u2010rich plasma or bone marrow aspirate concentrate should be considered, with evolving literature to support their use. Ultrasound percutaneous tendon scrapping with a needle supplemented with the aforementioned injections is an emerging treatment option that the authors have found to be helpful, although further studies are required. Surgical intervention is considered after failure of nonoperative treatments, and typically occurs in tears greater than 50% of the tendon thickness and in tendons with increased thickness (&gt;8.8 mm). Open or arthroscopic debridement can be considered, with no studies showing superior outcomes with either technique; however, no high\u2010quality comparison studies exist. The authors prefer an open technique where, much like a bone\u2013patellar tendon\u2013bone harvest, the unhealthy proximal tendon and bone are excised with then closure of the healthy tendon with absorbable sutures. Suture anchor repair may also be used when necessary. In a recent systematic review, surgical management of patellar tendinopathy has been shown to result in improved patient\u2010reported outcomes with return to sport at high levels.\n                    <jats:sup>1<\/jats:sup>\n                    Treatment for the difficult and sometimes frustrating pathology of patellar tendinopathy continues to evolve, with biologic and less\u2010invasive ultrasound\u2010based treatments showing promise, and surgical intervention providing reliable outcomes.\n
