BACKGROUND
The purpose of this study was to assess the outcomes of patients who underwent combined hip arthroscopy and periacetabular osteotomy with acetabular focal chondral defects and compare these outcomes with a group of patients without focal chondral defects.
METHODS
A retrospective review looking at patients who underwent hip arthroscopy and/or periacetabular osteotomy was performed. Minimum 2-year follow-up, Tönnis grade 0-1, and a Beck chondromalacia stages 4-5 were included. Twenty-eight hips met inclusion criteria. These patients were then matched 1:1 and compared.
RESULTS
The average acetabular chondral defect size was 144.3 mm ± standard deviation 116.2. Postoperative, modified Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, and University of California Los Angeles scores were similar between groups (P = .382, P = .755, P = .763, respectively). At the last follow-up, Tönnis grade was similar between groups (P = .552). No association between having a defect and increased risk of failure was noted (hazard ratio 1.35 [95% CI 0.43-4.24], P = .607).
CONCLUSION
We found that patients with focal chondral defects did similar to a comparison group of patients without chondral defects.
背景
本研究旨在评估髋关节镜检查和髋臼周围截骨术联合治疗髋臼局灶性软骨缺损患者的疗效，并与无局灶性软骨缺损的患者进行比较。
方法
对接受髋关节镜检查和/或髋臼周围截骨术的患者进行回顾性研究。纳入标准为：至少随访 2 年，Tönnis 分级 0-1 级，Beck 软骨软化分期 4-5 级。28 髋符合纳入标准，然后进行 1:1 配对比较。
结果
髋臼软骨缺损的平均大小为 144.3mm ± 116.2mm。术后改良 Harris 髋关节评分、髋关节残疾和骨关节炎结局评分以及加利福尼亚大学洛杉矶分校评分在两组间无差异（P=0.382、P=0.755、P=0.763）。末次随访时，两组的 Tönnis 分级无差异（P=0.552）。缺损与失败风险增加之间无相关性（风险比 1.35[95%CI 0.43-4.24]，P=0.607）。
结论
我们发现有局灶性软骨缺损的患者与无软骨缺损的患者比较，疗效相似。
