The medial patellofemoral ligament (MPFL) is frequently torn and attenuated in patients with acute or chronic patellar instability. The mainstay for surgical treatment has become MPFL reconstruction to reestablish the checkrein to lateral patellar translation. The authors describe a technique for MPFL reconstruction with concomitant lateral retinacular lengthening with a gracilis allograft and adjustable loop cortical femoral fixation performed chiefly from a lateral parapatellar approach. This technique allows for reliable retensioning of the medial and lateral patellar soft tissues while avoiding complications associated with techniques that use interference screw fixation. Successful execution of this procedure provides a strong MPFL construct that allows patients to undergo early aggressive rehabilitation and return to activities.
内侧髌股韧带（MPFL）在急性或慢性髌骨不稳定患者中经常发生撕裂和松弛。手术治疗的主要方法已变为MPFL重建，以重新建立对髌骨向外侧移位的牵制。作者描述了一种MPFL重建技术，同时采用股薄肌同种异体移植物进行外侧支持带延长，并主要通过外侧髌旁入路进行可调节袢皮质股骨固定。该技术能够可靠地重新拉紧髌骨内外侧的软组织，同时避免了与使用挤压螺钉固定技术相关的并发症。成功实施该手术可提供一个坚固的MPFL结构，使患者能够早期积极康复并恢复活动。
