Abstract:
Lateral retinacular release of the patella is the main surgical treatment for excessive lateral pressure syndrome. It was first described by Merchant and Mercer in 1974. The main complications of arthroscopic lateral retinacular release are hemarthrosis and medial patellar instability. The main causes of these complications are the disturbance of the synovial membrane of the joint capsule and excessive release of the lateral retinaculum. In this article, we introduce a method for arthroscopic lateral retinacular release that maintains the overall structure of the joint capsule: capsule-uncut immaculate (CUI) lateral retinacular release.
