内侧髌股韧带重建：一种无植入物技术
简介
该研究描述了一种无植入物的内侧髌股韧带（MPFL）重建技术，使用半腱肌自体移植物，采用改良Fithian法进行髌骨固定，并通过内收肌腱环（“adductor sling”）完成股骨侧固定。关键发现：该技术避免了锚钉或界面螺钉等植入物，降低了手术僵硬度和成本，同时保持了移植物解剖定位和动态稳定性评估。临床意义：对于髌股关节不稳，尤其是在资源有限地区，这种无植入…
英文摘要
Medial patellofemoral ligament (MPFL) reconstruction is a widely performed procedure for patellofemoral instability. However, there is no consensus on the optimal graft choice, fixation method, or surgical technique. Most described techniques require implants such as anchors or interference screws, which increase stiffness and cost. In many developing countries, the high cost of implants limits access to surgery. We describe a reproducible, effective, and low-cost MPFL reconstruction technique that avoids implants, using a semitendinosus autograft, a modified Fithian technique for patellar fixation, and an adductor tendon loop ("adductor sling") for femoral fixation. The technique was developed to minimize complications related to implant use and reduce costs, while maintaining anatomical graft placement and dynamic stability assessment. This implant-free MPFL reconstruction technique offers a safe and affordable surgical option for the management of patellofemoral instability, particularly in resource-limited settings. Socioeconomic factors should be considered when selecting a reconstruction method.
