Abstract

Objectives The aim of this study was to explore the clinical outcomes and long-term survival of patellofemoral arthroplasty in treatment of isolated patellofemoral osteoarthritis. Methods We retrospectively studied a total of 46 type Y-L-Q PFAs that were designed at our institution in 38 patients. Implant survivorship was analyzed with a follow-up of 18.9–29.6 years. Knee Society Score (KSS), Oxford Knee Score (OKS), and University of California Los Angeles activity scale (UCLA) were used to assess functional outcomes. Results The implant survivorship was 83.6% at 15 years, 76.8% at 20 years, and 59.4% at 25 years 14 PFAs in 12 patients were revised into total knee arthroplasty at 16.0 ± 6.7 years; 13 for progression of tibiofemoral osteoarthritis and one for polyethylene wear. The mean Knee Society Score objective scores and functional scores were 73.0 ± 17.5 (range, 49–95) and 56.4 ± 28.9 (range, 5–90), respectively. The mean Oxford Knee Score was 25.8 ± 11.5 (range, 8–44). Conclusion Type Y-L-Q patellofemoral arthroplasty can be an effective method for treating isolated patellofemoral osteoarthritis with satisfactory survival.

髌股关节置换术治疗孤立性髌股骨关节炎的长期临床效果。

目的:本研究的目的是探讨髌股关节置换术治疗孤立性髌股骨关节炎的临床疗效和长期生存率。方法:我们回顾性研究了我院设计的38例患者的46种Y-L-Q型PFAs。随访18.9-29.6年，分析种植体存活情况。膝关节社会评分(KSS)、牛津膝关节评分(OKS)和加州大学洛杉矶分校活动量表(UCLA)用于评估功能预后。结果:植入物15年生存率为83.6%，20年生存率为76.8%，25年生存率为59.4%，12例患者14例PFAs在16.0±6.7年改行全膝关节置换术;13例用于胫股骨关节炎进展，1例用于聚乙烯磨损。膝关节社会评分客观评分和功能评分平均分别为73.0±17.5分(范围49-95)和56.4±28.9分(范围5-90)。平均牛津膝关节评分为25.8±11.5(范围8-44)。结论:Y-L-Q型髌股关节置换术是治疗孤立性髌股骨关节炎的有效方法，生存率满意。
