Abstract
OBJECTIVE/METHODS: We compared short-term outcomes following 40 traditional, cemented total knee arthroplasty (TKA) to the first 40 cemented robotic-arm assisted TKA (raTKA) and analyzed the learning curve for raTKA.
RESULTS
LOS was longer for traditional TKA compared to raTKA (1.92 vs. 1.27days, p < 0.0001). There was no difference in surgical time between the second 20 raTKA and all traditional TKA cases (81.1 vs. 78.3 mins, p = 0.254). raTKA patients had improved 90-day ROM (+3.8° vs. -8.7°, p < 0.05) but comparable complications rates, Knee Society Scores, and patient-reported outcomes at all timepoints.
CONCLUSION
Despite comparable outcomes, the learning curve for raTKA appeared to progress rapidly.
摘要
目的/方法：我们将40例传统骨水泥型全膝关节置换术（TKA）与前40例骨水泥型机器人辅助全膝关节置换术（raTKA）的短期结果进行了比较，并分析了raTKA的学习曲线。
结果
与raTKA相比，传统TKA的住院时间更长（1.92天对1.27天，p<0.0001）。后20例raTKA与所有传统TKA病例的手术时间无差异（81.1分钟对78.3分钟，p=0.254）。raTKA患者90天的关节活动度有所改善（+3.8°对-8.7°，p<0.05），但在所有时间点的并发症发生率、膝关节协会评分和患者报告的结果相当。
结论
尽管结果相当，但raTKA的学习曲线似乎进展迅速。
