Smith J, Sellon JL (2014) Comparing PRP injections with ESWT for athletes with chronic patellar tendinopathy. Clin J Sport Med 24(1):88–89 Patellar tendinopathy is mainly a clinical diagnosis made through a detailed history and meticulous physical examination. Appropriate questions which will cue in the diagnosis: Sport practiced, schedule of practice and competition, which position the athlete plays, and level of performance. The patient will usually complain of well-localized pain and tenderness on the inferior tip of the patella. [12] [2]

Biedert R, Vogel U, Friedrichs NF. (1997) Chronic patellar tendinitis: a new surgical treatment. Sports Exerc Inj. 3:150–154. Multiple theories have been proposed for the pathogenesis of patellar tendinopathy, mechanical, vascular, and impingement related. However, the chronic overload theory is the most commonly reported. Repetitive overload on the knee extensor tendons will cause it to weaken progressively, eventually leading to failure. Microscopic failure occurs within the tendon at high loads and eventually leads to alterations at the cellular level, which undermine its mechanical properties. Tendon micro-trauma may cause individual fibril degeneration due to stress across the tendon. As the fibril degeneration becomes ongoing, chronic tendinopathy will ensue.
