为了矫正髌骨不稳定伴髌骨发育不良的髌骨不稳定，常采用加深髌骨成形术联合其他髌骨稳定手术。然而，各种并发症，包括髌股骨关节炎和膝前疼痛可能是影响临床结果的负面因素。在这里，我们描述了两例慢性髌骨不稳定伴股骨粗隆发育不良的病例，我们对他们进行了髌股关节成形术（PFA），而不是股骨粗隆成形术，并结合内侧髌股韧带（MPFL）重建。在这两个病例中，PFA作为金属肌腱成形术，改善了髌股关节的一致性，并取得了良好的临床效果，术后长达3年，没有复发髌骨不稳定。这种手术可以被认为是慢性髌骨不稳定伴髌骨发育不良病例的一种选择。
Deepening trochleoplasty combined with other patella stabilization procedures is often performed to correct patellar instability with trochlear dysplasia. However, various complications following trochleoplasty including patellofemoral osteoarthritis and anterior knee pain can be negative factors affecting the clinical results. Here, we describe two cases of chronic patellar instability with trochlear dysplasia on whom we performed patellofemoral arthroplasty (PFA), instead of trochleoplasty, in conjunction with medial patellofemoral ligament (MPFL) reconstruction. In both cases, PFA, acting as metallic trochleoplasty, improved the congruency of patellofemoral joint, and achieved good clinical results for up to 3 years postoperatively without recurrent patellar instability. This procedure could be considered as one option for cases of chronic patellar instability with trochlear dysplasia.
