Posteromedial knee pain is a common clinical problem. It is often accompanied by degenerative changes or tears in the posterior horn of the medial meniscus and/or pain during deep flexion of the knee. In more advanced cases, it is accompanied by the osteophytic formation of a cam lesion that develops gradually in the posterior of the medial condyle of the femur and, with it (or less frequently without it), an osteophytic lesion at the posterior of the tibia (i.e. pincer lesion) occurs. It is believed that resection of the cam lesion may delay the progression of knee osteoarthritis, similarly to repairing the posterior horn of the medial meniscus. In this technical note, we describe a 2-portal technique for resection of cam lesions by posteromedial knee arthroscopy using anatomic landmarks. Using both portals provides better visualization and a better approach.
膝关节后内侧疼痛是一种常见的临床问题。它常伴有内侧半月板后角的退行性改变或撕裂，和/或膝关节深度屈曲时疼痛。在更严重的病例中，它伴有股骨内侧髁后方逐渐形成的凸轮样病变的骨赘形成，并且随之（或较少见地不伴随）出现胫骨后方的骨赘病变（即钳夹样病变）。据信，切除凸轮样病变可能会延缓膝关节骨关节炎的进展，类似于修复内侧半月板后角。在本技术说明中，我们描述了一种通过后内侧膝关节镜检查使用解剖标志切除凸轮样病变的双入路技术。使用两个入路可提供更好的视野和更佳的入路方式。
