文题释义:
旋转高屈曲型假体:
旋转高屈曲型假体是由美国捷迈公司研制的NexGen LPS-Flex Mobile Bearing假体,主要用于全膝关节置换治疗。其优势在于置入后屈曲度高达155°,可使患者获得良好的关节活动度;其聚乙烯衬垫下方可以与胫骨平台假体之间自由旋转,同时降低接触应力,降低聚乙烯衬垫背侧磨损,更符合人体的自然运动模式;另外该假体使用寿命长,可降低全膝关节置换的翻修率。
人工全膝关节置换国内目前以固定平台型假体和旋转平台型假体进行全膝关节置换为主导:试验中患者的主要特点为中年、身材较高大、膝关节已经出现不同程度的畸形,生活质量较低者,但选择旋转高屈曲型假体或固定平台型假体是需要关注的问题。文章回顾性分析了人工全膝关节置换中使用旋转高屈曲型假体治疗中年骨性关节炎的中短期临床疗效,记录膝关节活动度和美国特种外科医院膝关节评分,总评假体置换的优良率,结果认为对于有较高的关节活动度、较年轻的患者来说,旋转高屈曲型假体的全膝关节置换具有潜在的运动学优势。
 

背景:人工全膝关节置换是膝关节骨性关节病终末期的主要治疗手段,如何根据患者的不同情况来选择假体置换,是目前关节外科领域关注的焦点之一。
目的:评价人工全膝关节置换中使用旋转高屈曲型假体治疗中年骨性关节炎的中短期临床疗效。
方法:回顾性分析柳州市人民医院2009年1月至2013年1月旋转高屈曲型假体治疗的中年骨性关节炎患者48例55膝。
结果与结论:①48例患者置入后获得23-42个月随访,平均(24.0±2.7)个月;②置入后患者膝关节活动度和美国特种外科医院膝关节评分明显增加,且末次随访美国特种外科医院膝关节评分优良率为85.4%;③所有患者无假体植入后感染、松动脱位等严重并发症发生。④结果提示旋转高屈曲型假体疗效确切,置入后关节活动度高,更符合人体自然的运动模式,假体寿命使用长,且翻修率较低,对需要有高屈曲活动的患者来说是一种较为理想的方法。

Abstract:

BACKGROUND: Total knee replacement is the main treatment for the end of the knee joint disease. How to choose prosthesis replacement according to the different situations of the patient is one of the focuses in the field of joint surgery.

OBJECTIVE: To evaluate middle or short term effects of rotating high-flexion prosthesis for the middle-aged patients with osteoarthritis of knee in total knee replacement.
METHODS: We retrospectively analyzed 48 osteoarthritis patients (55 knees) undergoing total knee replacement with rotating high-flexion prosthesis in the Liuzhou People’s Hospital from January 2009 to January 2013.
RESULTS AND CONCLUSION: (1) Forty-eight patients were followed up for 23-42 months, mean (24±2.7) months. (2) Knee range of motion and Hospital for Special Surgery knee score were significantly increased after implantation. The excellent and good rate of Hospital for Special Surgery knee score was 85.4%. (3) No infection, loosening or dislocation occurred in all patients. (4) These findings suggest that curative effect of rotating high-flexion prosthesis is definite. After implantation, the range of motion was high, which was accorded with movement pattern of the human body. Prosthesis has a long life, and its repair rate is low. It is an ideal method for the middle-aged patients who want to perform high-flexion activities.
