Jumper's knee is the result of violent and repeated contractions of quadriceps muscle caused by rapid acceleration and deceleration, jumping and kicking that load on patellar tendon stressing its mechanical resistance. The porpose of this retrospective study is to analyze the results, after the debridment of the patellar tendon and the patellar apex abrasion performed by arthroscopy, at a mean follow-up of seven years. From 1996 to 2006, sixty-four patients (seventy-three knees) affected by jumper's knee underwent surgical tretment after failure of nonoperative treatment. All knees were operated on by the same surgeon using the same surgical technique: arthroscopic debridement of the articular face of patellar tendon and arthroscopic abrasion of patellar apex. Pre-operative and post-operative evaluation was made according to IKDC score, Lysholm Knee Scale and VISA-P score.Background
