Abstract
Mucoid degeneration of the anterior cruciate ligament (ACL) and associated ganglion cysts can cause chronic knee pain and motion restriction, often due to intercondylar notch stenosis. This technical note describes an arthroscopic approach combining notchplasty and radiofrequency ablation to relieve impingement while preserving ACL integrity. The procedure involves diagnostic arthroscopy, cyst debridement, and targeted notchplasty at 3 key areas: superior‐lateral anterior rim, anterior roof, and posterolateral roof. Radiofrequency ablation removes excess mucoid tissue, optimizing notch space. This reproducible technique provides an effective treatment for mucoid degeneration of the ACL, especially in cases with notch stenosis. Technique Video video See video under supplementary data.
