Arthroscopic Collagenous Matrix Therapy for Osteochondral Lesions of the Talus

Osteochondral lesions of the talus frequently are seen in injuries, typically caused by trauma or repetitive stress, which affect both the cartilage and the underlying bone of the ankle joint. If left untreated, these lesions can result in chronic pain, joint instability, and impaired function. Treatment options traditionally range from conservative approaches to surgical procedures, such as microfracture, osteochondral autografts, and allografts. In this Technical Note, we discuss our experience with anterior ankle arthroscopy, specifically focusing on debridement, microfracture, and the application of cell-free collagenous matrix in osteochondral lesions of the talus.
