Accurate positioning of the femoral insertion of the medial patellofemoral ligament (MPFL) is the main difficulty in MPFL reconstruction. This article describes an all-arthroscopic MPFL reconstruction procedure. Preoperative 3-dimensional computed tomography assists in MPFL patellar and femoral insertion positioning, with arthroscopic reconfirmation of femoral insertion positioning through a subcutaneous tunnel during surgery. In the socket-anchor technique for patellar insertion fixation, a 10-mm-deep bone tunnel (socket) is created along a previously located guide pin at the MPFL patellar insertion; then, an absorbable suture anchor is inserted into the end of the socket to fix the tendon graft. This technique provides the advantages of being minimally invasive, yielding accurate positioning, ensuring a sufficient tendon-bone interface healing area of the graft, and having no need for intraoperative fluoroscopy.
髌股内侧韧带（MPFL）股骨端插入点的准确定位是MPFL重建的主要难点。本文描述了一种全关节镜下MPFL重建手术。术前三维计算机断层扫描有助于MPFL髌骨和股骨端插入点的定位，术中通过皮下隧道对股骨端插入点定位进行关节镜再次确认。在用于髌骨端插入固定的套接-锚钉技术中，沿着MPFL髌骨端插入点处预先定位的导针创建一个10毫米深的骨隧道（套接）；然后，将可吸收缝线锚钉插入套接末端以固定肌腱移植物。该技术具有微创、定位准确、确保移植物有足够的腱-骨界面愈合面积且无需术中透视等优点。
