Lateral retinacular release is still being performed in patients with recurrent patellar dislocation as an additional procedure with distal realignment or medial patellofemoral ligament (MPFL) reconstruction. However, consensus remains lacking regarding suitable indications for lateral retinacular release. A 20-year-old woman presented with patellar instability in both medial and lateral directions after undergoing lateral retinacular release with MPFL reconstruction. She displayed inherent systemic joint laxity meeting all seven Carter-Wilkinson criteria. Simultaneous MPFL revision and lateral retinaculum reconstruction successfully improved patellar instability in both directions. This case provides an example of iatrogenic medial patellar instability after failed lateral retinacular release.
对于复发性髌骨脱位患者，在进行远端重新排列或内侧髌股韧带（MPFL）重建等附加手术时，仍会实施外侧支持带松解术。然而，对于外侧支持带松解术的合适适应症仍缺乏共识。一名20岁女性在接受外侧支持带松解术并重建MPFL后，出现了髌骨内外侧方向的不稳定。她表现出符合所有七项卡特 - 威尔金森标准的先天性全身关节松弛。同时进行MPFL翻修和外侧支持带重建成功改善了髌骨在两个方向上的不稳定。该病例提供了一个外侧支持带松解术失败后医源性内侧髌骨不稳定的例子。
