Arthroscopic Debridement and Fixation of Osteochondritis Dissecans Lesions of the Medial Femoral Condyle

Arthroscopy Techniques, Volume 13, Issue 10, October 2024.
Abstract Unstable osteochondritis dissecans lesions of the medial femoral condyle have classically been treated with open reduction and fixation under direct visualization through an open arthrotomy. Given the value of avoiding open arthrotomies, we present an arthroscopic approach for lesion elevation, debridement, and fixation.
