联合外侧髌股韧带与外侧髌胫韧带重建治疗内侧髌骨不稳
简介
该技术报告介绍了一种使用单根半腱肌同种异体移植物，同时重建外侧髌股韧带和外侧髌胫韧带的可重复开放手术方法，用于治疗因外侧支持带过度松解导致的内侧髌骨不稳。该技术通过恢复近端和远端外侧约束结构，实现解剖重建，并降低残留不稳的风险。
英文摘要
Medial patellar instability is an uncommon but debilitating condition that may arise following excessive lateral retinacular release. The lateral patellofemoral ligament and lateral patellotibial ligament function as key static stabilizers that resist medial patellar translation throughout knee flexion. This technical note describes a reproducible open technique for combined lateral patellofemoral ligament and lateral patellotibial ligament reconstruction using a single semitendinosus allograft to restore both proximal and distal lateral restraints. This technique provides anatomic reconstruction while minimizing the risk of residual instability.
