Osteochondritis dissecans (OCD) of the knee is a subchondral bone abnormality that results in the separation of the articular cartilage and bone with subsequent progression to osteoarthritis. Unstable OCD lesions should undergo fixation to preserve the natural contour of the articular surface. Although several fixation procedures have been reported, the appropriate procedure remains unknown. Because the bony portion of the OCD lesion is usually thin, it is difficult to fix firmly with conventional methods. We began fixing OCD lesions with knotless PushLock anchors and sutures and have obtained satisfactory results. This report describes this fixation method that uses the PushLock suture anchor to treat unstable OCD lesions. This procedure also can be applied for traumatic osteochondral fractures.
膝关节剥脱性骨软骨炎（OCD）是一种软骨下骨异常，可导致关节软骨和骨分离，随后发展为骨关节炎。不稳定的OCD病变应进行固定，以保留关节表面的自然轮廓。尽管已经报道了几种固定方法，但合适的方法仍然未知。由于OCD病变的骨部分通常很薄，用传统方法很难牢固固定。我们开始使用无结PushLock锚钉和缝线固定OCD病变，并取得了满意的效果。本报告描述了这种使用PushLock缝线锚钉治疗不稳定OCD病变的固定方法。该方法也可应用于创伤性骨软骨骨折。
