Despite excellent results, there is a lack of prospective studies analysing functional outcome and quality of life after computer-navigated total knee arthroplasty. Fifty-two patients were investigated before and 6 months after surgery with the OrthoPilot navigation system (Aesculap, Germany). We used the SF-36 Health Survey, the visual analog scale (VAS), the Lequesne score and the Knee Society Score (KSS) for assessment. The operation was carried out by one single surgeon. At follow-up, the study population achieved a significant pain reduction on the VAS from 71 to 21 points, an average decline of the Lequesne score from 16 to 7 points coming along with a significant ascent of the KSS from 84 to 157 points. Concerning the SF-36 Health Survey, most of the patients re-achieved age- and gender-matched scores. Poor results were obtained in patients with multiple comorbidities and a severe flexion contracture preoperative.
尽管取得了出色的效果，但仍缺乏对计算机导航全膝关节置换术后功能结局和生活质量进行分析的前瞻性研究。我们使用OrthoPilot导航系统（德国蛇牌）对52例患者在手术前和术后6个月进行了调查。我们使用SF-36健康调查、视觉模拟量表（VAS）、Lequesne评分和膝关节协会评分（KSS）进行评估。手术由一名外科医生完成。在随访时，研究人群的VAS疼痛评分从71分显著降低至21分，Lequesne评分平均从16分降至7分，同时KSS评分从84分显著升至157分。关于SF-36健康调查，大多数患者重新达到了年龄和性别匹配的评分。术前患有多种合并症和严重屈曲挛缩的患者结果较差。
