Medial patellofemoral ligament (MPFL) reconstruction has gained in popularity over the past 15 years, with most studies showing a clear advantage over techniques such as MPFL repair or medial imbrication for the treatment of patellar instability. A debate continues as to the type of fixation on the patella, tunnel versus suture anchor, as well as the number of fixation points. In fact, some senior patellofemoral surgeons have opted away from patellar bony fixation altogether to avoid complications associated with patellar fixation such as fracture or penetration of the articular cartilage. In my practice, I prefer to use 2 all-suture suture anchors for patellar fixation as there is minimal risk of fracture or significant cartilage damage compared with tunnel drilling or placement of larger suture anchors. The graft choice for MPFL reconstruction has been shown to be relatively unimportant, and for this reason, I typically choose gracilis allograft to avoid graft-site morbidity and hamstring weakness.
在过去15年中,内侧髌股韧带(MPFL)重建术越来越受欢迎,大多数研究表明,与MPFL修复或内侧重叠缝合等技术相比,该技术在治疗髌骨不稳方面具有明显优势。关于髌骨固定的类型(骨隧道固定与缝线锚钉固定)以及固定点的数量,仍存在争议。事实上,一些资深的髌股关节外科医生已完全放弃髌骨骨性固定,以避免与髌骨固定相关的并发症,如骨折或关节软骨穿透。在我的临床实践中,我更倾向于使用2枚全缝线锚钉进行髌骨固定,因为与骨隧道钻孔或使用更大的缝线锚钉相比,骨折或严重软骨损伤的风险极小。MPFL重建的移植物选择相对不重要,因此,我通常选择股薄肌同种异体移植物,以避免供区并发症和腘绳肌肌力减弱。
