The purpose of this prospective study was to present the experience of a single center on patellofemoral arthroplasty, in terms of patient-related outcomes.
From January 2005 to January 2016, 42 patients with isolated patellofemoral osteoarthritis were treated. The patients were assessed using the Oxford Knee Score preoperatively, and one, five, and eight year(s) after surgery. The data of the patients were analyzed using linear mixed effects models. A P value of 0.05 was considered statistically significant.
Among 42 patients who underwent patellofemoral arthroplasty, only 25 patients (31 limbs involved) had records up to 5 years. There was a significant clinical improvement of Oxford Knee Score postoperatively (P < 0.05), lowering the score on average by 10.4 ± 1.5 one year after surgery and 8.9 ± 1.9 five years after surgery. This improvement was independent of the types of implants (P > 0.05), gender (P > 0.05), age (P < 0.05), and body mass index (BMI) (P < 0.05).
Patellofemoral arthroplasty can significantly improve the knee function, and this improvement is independent of the type of implant, gender, age, and BMI. However, further studies will need to assess the long-term outcomes of PFA.
本前瞻性研究旨在介绍单中心在髌股关节置换术方面与患者相关结局的经验。
2005年1月至2016年1月，对42例孤立性髌股关节炎患者进行了治疗。术前以及术后1年、5年和8年使用牛津膝关节评分对患者进行评估。使用线性混合效应模型分析患者数据。P值<0.05被认为具有统计学意义。
在接受髌股关节置换术的42例患者中，只有25例患者（涉及31个肢体）有长达5年的记录。术后牛津膝关节评分有显著临床改善（P<0.05），术后1年平均评分降低10.4±1.5，术后5年降低8.9±1.9。这种改善与植入物类型（P>0.05）、性别（P>0.05）、年龄（P<0.05）和体重指数（BMI）（P<0.05）无关。
髌股关节置换术可显著改善膝关节功能，且这种改善与植入物类型、性别、年龄和BMI无关。然而，需要进一步研究来评估髌股关节置换术的长期结局。
