Reconstruction of the medial patellofemoral ligament (MPFL) is an effective surgical method for the treatment of lateral patellar instability. At present, there is not much controversies regarding the femoral attachment, however, the controversies regarding patellar attachment versus attachment, number of graft strands, tension, isometry and so on. The following electronic databases will be searched: PubMed, the Cochrane Library, Embase, Web of Science, Medline. We will consider articles published between database initiation and March 2021. MPFL in the subject heading will be included in the study. Language is limited to English. Research selection, data extraction, and research quality assessment were independently completed by 2 researchers.
MPFL reconstruction is a reliable technique for the treatment of patellofemoral instability. The Schöttle point is still the mainstream method for locating the femoral attachment, the patellar attachment for single-bundle is located at the junction of the proximal one third and the distal two third of the longitudinal axis of the patella. For double-bundles, one is located in the proximal one third of the medial patellar edge and another is in the center of the patellar edge. Meanwhile, the adjustment of graft tension during operation is very important.
髌股内侧韧带（MPFL）重建是治疗髌骨外侧不稳定的一种有效手术方法。目前，关于股骨附着点的争议不多，然而，关于髌骨附着点、移植物束数、张力、等长性等存在争议。将检索以下电子数据库：PubMed、Cochrane图书馆、Embase、Web of Science、Medline。我们将纳入数据库建立至2021年3月期间发表的文章。研究将纳入主题词中包含MPFL的文章。语言限于英语。研究筛选、数据提取和研究质量评估由两名研究人员独立完成。
MPFL重建是治疗髌股不稳定的可靠技术。朔特勒点仍是定位股骨附着点的主流方法，单束的髌骨附着点位于髌骨纵轴近端三分之一与远端三分之二的交界处。对于双束，一束位于髌骨内侧边缘的近端三分之一处，另一束位于髌骨边缘的中心。同时，术中移植物张力的调整非常重要。
