Knotless Suture Anchor Fixation of a Traumatic Osteochondral Lesion of the Lateral Femoral Condyle.

Abstract

Osteochondral injuries commonly occur after lateral patellar instability events. Recognition and early intervention of displaced fragments is key to maintaining the viability of the fragment and congruency of the articular surface. Multiple fixation techniques exist for achieving stable fixation of displaced osteochondral lesions, including metal or bioabsorbable screws and all suture techniques. In this Technical Note, we describe a technique for internal fixation of a displaced osteochondral fragment of the lateral femoral condyle using knotless suture anchors. This technique affords minimally invasive restoration of the native anatomy with excellent stability of the fracture fragment, allowing early range of motion and ambulation.
