Several techniques have been described for reconstruction of the medial patellofemoral ligament (MPFL). The anatomical insertion of the MPFL has been defined; however, there are no reports describing the accuracy of femoral graft positioning assessed postoperatively.
To analyze our femoral tunnel positioning for MPFL reconstruction in correlation with our clinical results.
Case series; Level of evidence, 4.
The authors reported a prospective series of 29 MPFL reconstructions with a minimum follow-up of 24 months. The tunnel positioning analysis was performed using plain radiographs and magnetic resonance imaging at 1-year follow-up.
Twenty-nine femoral tunnels were analyzed; 20 femoral tunnels (69%) were considered to be in good position on plain radiographs. On magnetic resonance imaging, the authors found 19 femoral tunnels (65%) in a proper location, 5 (17.5%) in a high position, and 5 in an anterior and/or high position.
The study highlights the difficulty of reproducible MPFL reconstruction. The surgical procedure continues to be improved and finding a reliable technique to anatomically place the graft remains challenging. Verifying femoral tunnel placement radiographically may be recommended during surgery.
已有多种技术被用于重建内侧髌股韧带（MPFL）。MPFL 的解剖止点已经明确，但尚无报道描述术后评估 MPFL 重建时股骨移植物定位的准确性。
分析我们行 MPFL 重建时股骨隧道的定位，并与临床结果相关联。
病例系列；证据等级，4 级。
作者报告了一项前瞻性的 29 例 MPFL 重建病例系列研究，随访时间至少为 24 个月。在术后 1 年随访时，通过平片和磁共振成像对隧道定位进行分析。
分析了 29 个股骨隧道；20 个（69%）股骨隧道在平片上被认为处于良好位置。磁共振成像显示，19 个（65%）股骨隧道位置合适，5 个（17.5%）位置偏高，5 个位于前侧和/或高位。
本研究强调了重复性 MPFL 重建的难度。手术操作仍在不断改进，寻找一种可靠的技术来进行解剖学定位移植物仍然具有挑战性。在手术期间，建议对股骨隧道的位置进行影像学验证。
