Jumper's knee: postoperative assessment. A retrospective clinical study.

Jumper's knee or infrapatellar insertional tendinopathy is a condition primarily found in athletes between 18 and 25 years of age who are engaged in explosive running and jumping sports. It is caused by microtears or partial macrotears through the patellar tendon. Conservative treatment is used as the primary approach. If conservative measures are insufficient or fail to relieve the symptoms, surgery is indicated. The patellar tendon is incised and the hyaline inflammatory tissue is removed. Twenty-six patients have been studied retrospectively, with specific attention to postoperative resumption of sports and residual subjective and objective findings. They all completed a detailed questionnaire and subsequently underwent a physical and ultrasound examination.
