Fixation of an Osteochondral Fracture of the Lateral Femoral Condyle With Knotless Suture Anchors.

Osteochondral fractures of the knee involve disruption of the subchondral bone and overlying cartilage, which can lead to instability and early osteoarthritis. These lesions often require immediate surgical fixation to preserve joint surface anatomy. Although several fixation methods exist, there is no universally accepted gold standard. Thin bony fragments often limit the effectiveness of traditional implants. We describe a knotless suture anchor technique (PushLock; Arthrex, Naples, FL) to achieve stable fixation and restore articular congruity in an unstable, traumatic osteochondral fracture.
