同种异体移植物内侧髌股韧带重建术:采用髌骨缝合锚钉与分层内侧重叠缝合技术
简介
该研究介绍了一种同种异体MPFL重建技术,采用股骨解剖隧道定位、髌骨全缝线锚钉固定及逐步内侧折叠缝合。该方法不仅恢复MPFL移植物的静态约束力,还通过重建内侧软组织动态稳定作用形成“缓冲效应”,可单独或联合骨/软骨手术实施。
英文摘要
Patellar instability commonly affects adolescents and young athletes and is associated with injury to the medial patellofemoral ligament (MPFL). MPFL reconstruction is a well-established treatment for recurrent instability; however, complications related to graft tensioning, fixation, and incomplete restoration of medial soft-tissue restraints persist. We describe a surgical technique for allograft MPFL reconstruction that emphasizes stepwise imbrication of the medial knee layers, anatomic femoral tunnel placement, and all-suture fixation to the patella. This approach restores both the static restraint provided by the MPFL graft and the dynamic stabilizing effect of the medial soft tissues, creating a "bumper effect" analogous to principles of shoulder stabilization. This technique provides a thoughtful and durable method for MPFL reconstruction and may be performed as an isolated procedure or in conjunction with adjunctive bony or cartilage procedures.
