In a prospective randomized control trial comparing computer-assisted vs conventional total knee arthroplasty, we previously reported that patients with coronal alignment within 3° of neutral had superior international knee society and Short-Form 12 (SF-12) physical scores at 6 weeks, 3 months, 6 months, and 12 months after surgery. Computer-assisted total knee arthroplasty achieved greater accuracy in implant alignment, and this correlated with better knee function and quality of life. At 5 years, 90 of 111 patients assessed in our original study were reviewed. Coronal alignment within 3° of neutral continued to be correlated with superior International Knee Society and SF-12 scores. Coronal alignment greater than 3° was associated with a significant decline in SF-12 mental health scores.
在一项比较计算机辅助与传统全膝关节置换的前瞻性随机对照试验中，我们之前报道称，冠状面对线在中立位 3°以内的患者在术后 6 周、3 个月、6 个月和 12 个月时具有更好的国际膝关节协会和简明健康调查量表 12 项（SF-12）生理评分。计算机辅助全膝关节置换术在植入物对线方面实现了更高的准确性，这与更好的膝关节功能和生活质量相关。在最初研究中评估的 111 名患者中，有 90 名在 5 年后进行了复查。冠状面对线在中立位 3°以内与更好的国际膝关节协会和 SF-12 评分相关。冠状面对线大于 3°与简明健康调查量表 12 项精神健康评分的显著下降相关。
