内轴膝置换治疗膝骨关节炎的满意度分析及初步疗效

分析内轴膝假体置换术后疗效，评估患者满意度。 方法对温州医科大学附属第二医院关节外科单一术者2016年8月至2017年10月期间使用内轴膝假体进行膝关节置换的患者进行至少1年随访，对患者的满意度及不满意原因进行调查和分析，并调查患者膝关节疼痛程度及关节活动度。 结果52例患者纳入此研究，手术时平均年龄(73±6)岁，随访时间(13.9±1.4)个月。内轴膝假体总体满意度达到90.38%，其中不满意的原因最主要是持续性膝关节疼痛，内轴膝假体置换后患者疼痛数字评分中位数M为0，四分位数间距为0，膝关节活动度为(93±12)°。 结论内轴膝置换治疗终末期膝骨性关节炎疗效确切，患者满意度高，术后膝关节持续性疼痛仍然是患者不满意最主要的原因。

Satisfaction and short-term clinical outcome of total knee arthroplsty using medial pivot knee for knee osteoarthritis

ObjectiveTo investigate clinical outcome of medial pivot(MP) knee prosthesis, the satisfaction rate and the causes of the dissatisfaction. MethodsA survey was used for collecting information from patients undergoing primary total knee arthroplasty (TKA) using MP prosthesis from August 2016 to October 2017. The minimum follow-up time was at least one year. The satisfaction and the causes of dissatisfaction were analyzed while the pain numeric rating scales(NRS) and range of motion were investigated. ResultsFifty-two patients performed TKA using this prosthesis were enrolled in this study, the average age was (73±6) years and the average follow-up time was (13.9±1.4)months. The satisfaction rate of MP prosthesis reached 90.38%. The most common cause of dissatisfaction was persistent pain around knee. The median of NRS score was 0, the inter-quartile range was 0. The range of motion was(93±12)°. ConclusionTKA using MP prosthesis achieves clinical good results and has a high satisfaction rate, yet persistent pain around knee after TKA is still the most common reason for dissatisfaction.
