使用与不用骨水泥固定人工膝关节置换术后疗效的比较

A Comparative Study of Clinical Results in Cemented Versus Cementless Alumina Ceramic Total Knee Arthroplasty

探讨使用与不用骨水泥固定氧化铝陶瓷制NCU型TKA术后的疗效。1989～1995年,为了治疗晚期骨性关节病及类风湿病,共施行NCU型TKA68例103个关节。对获得平均随访5年8个月的65例99个关节的以胫骨假体为中心的临床评价及X线计测的结果进行了比较性分析。临床评价方法是以JOA膝关节评价基准为标准,X线的评价方法是将术前、术后、最终调查时的正侧位X线照片数字化后输入电子计算机利用电脑软件系统进行了计测与评价。65例99个关节TKA术后经随访5年以上的结果表明NCU型TKA术后获得了比较良好的疗效。术后并发症7％,再手术率5％,不用骨水泥组疗效劣于使用骨水泥固定组,两组间的疼痛评分及透亮线出现率的差异均有显著性统计学意义。

To report the results of a comparative study in cemented versus cementless Nagoya City University (NCU) type alumina ceramic total knee arthroplasty (TKA) . During the period from 1989 to 1995, NCU TKA were performed in 103 joints of 68 patients with osteoarthritis (OA) or rheumatoid arthritis (RA). Adequate records were obtained in 99 joints of 65 patients with mean follow - up periods of 5 years 8 months. This study was undertaken to compare the clinical results of tibial components with cemented versus cementless fixation in NCU TKA. Clinical evaluation was done using the Japanese Orthopaedic Association (JOA) Knee Score and radiographic measurement of tibial components was assessed using computer software.The clinical results of 99 knees with NCU TKA with mean follow-up of more than 5 years were relatively good.The complication rate was 7% , and the reoperation rate was 5% (including revision rate 3%) .The result of cementless group wors than the cemented group. These differences were statistical significance.
