title: Arthroscopic protocol for treatment of knee extension block after patellar ACL reconstruction.
abstract: This study presents a new protocol for arthroscopic approach based on the treatment of 36 patients with extension block of the knee as a result of intra-articular reconstruction of the anterior cruciate ligament (ACL) using the patellar tendon. Arthroscopy not only allowed the identification of the active mechanical extension block of the knee, but also the passive mechanical block that can occur with a functional or loose ligament. This protocol can be useful in the treatment of postoperative extension block of the knee as a complication of ACL reconstruction.
