The lateral patellofemoral ligament acts to resist medial displacement of the patella. When medial subluxation occurs, it usually has an iatrogenic cause such as prior lateral release, an over-tightened medial patellofemoral ligament reconstruction, or detachment of the vastus lateralis from the patella. The justification for lateral retinacular release has historically been to address extensor mechanism issues such as imbalance of the mechanism due to increased retinacular tension. We present a Technical Note on the treatment of chronic medial patellar instability due to a previous lateral retinacular release using a soft-tissue reconstruction approach with a semitendinosus allograft.
髌股外侧韧带起到抵抗髌骨向内侧移位的作用。当发生髌骨内侧半脱位时，其通常有医源性原因，如既往的外侧松解、髌股内侧韧带重建过紧或股外侧肌从髌骨上的附着处分离。从历史上看，外侧支持带松解的理由是解决伸膝装置问题，如由于支持带张力增加导致的装置失衡。我们发表一篇技术说明，介绍使用半腱肌同种异体移植物的软组织重建方法治疗既往外侧支持带松解所致的慢性髌骨内侧不稳。
