| 目的 探讨在初次人工全膝关节置换术（total knee arthroplasty, TKA）中应用Legion工具完成Genesis Ⅱ膝关节假体置换术的可行性及临床意义。方法 将中国人民解放军总医院第一医学中心收治的60例单侧内翻型初次TKA病人按随机数字表法分成Legion工具组及Genesis工具组，所有病人均采用Genesis Ⅱ假体，分别采用对应的工具为两组病人完成手术。对病人术前及术后的美国膝关节协会评分（Knee Society Scores, KSS）、最大屈曲角度、术后人工关节被遗忘指数（Forgotten Joint Scores, FJS）及影像学指标进行对比分析。结果 两组病人均获得1年随访，未出现切口相关并发症；术后3个月Legion工具组KSS临床评分及功能评分均高于Genesis工具组［（81.55±4.81）分 vs. （79.05±4.10）分，t=2.165，P=0.035；（84.89±4.60）分 vs. （81.33±5.14）分，t=2.820，P=0.007）］，术后12个月两组KSS评分的差异无统计学意义；术后12个月Legion工具组FJS评分优于Genesis工具组［（94.03±6.50）分 vs. （89.62±6.10）分，t=2.706，P=0.009）］，病人膝关节最大屈曲角度较Genesis工具组大（123.48°±7.63° vs. 108.19°±9.12°，t=2.436，P=0.018）。结论 使用Legion工具行Genesis Ⅱ置换术，可以发挥其简单、精准、微创、个性化的特点，获得更好的临床疗效。 |

| Objective To investigate the feasibility and clinical significance of Genesis Ⅱ primary total knee arthroplasty with the tools of Legion knee system. Methods Sixty patients with varus knee who underwent unilateral Genesis Ⅱ primary total knee arthroplasty in Chinese PLA General Hospital were divided into two groups randomly: the Legion Tool group was given the tools of Legion knee system, and the Genesis Tool group was subjected to the tools of Genesis Ⅱ knee system. The Knee Society Scores (KSS) and maximum flexion degrees before and after surgery, Forgotten Joint Scores (FJS) and X-ray images after surgery between two groups were compared. Results All patients were followed up for one year without any incision-related complications. The clinical scores and functional scores of the KSS in the Legion tool group were significantly higher than those in the Genesis tool group at 3rd month post-surgery (81.55±4.81 vs. 79.05±4.10, t=2.165, P=0.035; 84.89±4.60 vs. 81.33±5.14, t=2.820, P=0.007). There was no significant difference in the KSS scores between the two groups at 12th month post-surgery. Both the FJS scores (94.03±6.50 vs. 89.62±6.10, t=2.706, P=0.009) and the maximum flexion degrees of the knee joint (123.48°±7.63° vs. 108.19°±9.12°, t=2.436, P=0.018) in the Legion tool group was superior to those in the Genesis tool group. Conclusion Genesis Ⅱ primary total knee arthroplasty with the tools of Legion knee system has the advantage of simplicity, precision, minimal invasion and individuation, as well as better clinical outcomes. |
