Periacetabular osteotomy (PAO) is widely recognized as a demanding surgical procedure for acetabular reorientation. Reports about the learning curve have primarily focused on complication rates during the initial learning phase. Therefore, our aim was to assess the PAO learning curve from an analytical perspective by determining the number of PAOs required for the duration of surgery to plateau and the accuracy to improve.

揭示髋臼周围截骨术的学习曲线。

髋臼周围截骨术（PAO）被广泛认为是髋臼重新定向的一项要求较高的外科手术。关于学习曲线的报告主要关注初始学习阶段的并发症发生率。因此，我们的目的是通过确定手术达到稳定状态所需的 PAO 数量以及提高的准确性，从分析角度评估 PAO 学习曲线。
