Robotic-assisted total knee arthroplasty (TKA) is a growing technique in adult reconstruction. The variations between robotic-assisted and conventional TKA could lead to changes in immediate postoperative outcomes. We aimed to evaluate for differences in postoperative pain, discharge day, as well as post-hospital disposition (home vs subacute rehabilitation facility [SAR]) between robotic-assisted and conventional TKA.
We retrospectively identified 2 cohorts of patients who underwent either conventional or robotic-assisted TKA between January 2019 and July 2019. Their average pain scores from postoperative day 0, day 1, and day 2 were recorded. Their postoperative discharge day was recorded, as well as their disposition to either home or a SAR. Preoperatively, all patients are offered robotic-assisted TKA, and only those who want the procedure and undergo a preoperative CT scan receive the robotic-assisted surgery. Statistical analysis was conducted using SPSS.
One hundred sixty-six patients were identified with 83 in each cohort. No differences between age, race, and gender were found. Despite minor variations in pain levels, the overall postoperative pain score analysis did not strongly favor one technique over the other. The robotic-assisted group had a significantly higher amount of patients discharged to home instead of a SAR and also had a shorter time to discharge than the conventional group.
Robotic-assisted TKA has similar postoperative pain scores compared with conventional TKA. The robotic-assisted cohort demonstrated other benefits including earlier discharge and are more likely to be discharged home instead of a SAR.
机器人辅助全膝关节置换术（TKA）是成人重建领域中一项不断发展的技术。机器人辅助TKA与传统TKA之间的差异可能导致术后即刻结果的变化。我们旨在评估机器人辅助TKA与传统TKA在术后疼痛、出院日期以及出院后去向（回家与亚急性康复机构[SAR]）方面的差异。
我们回顾性确定了2019年1月至2019年7月期间接受传统或机器人辅助TKA的两组患者。记录他们术后第0天、第1天和第2天的平均疼痛评分。记录他们的术后出院日期以及回家或去SAR的去向。术前，所有患者均被提供机器人辅助TKA，只有那些希望接受该手术并进行术前CT扫描的患者才接受机器人辅助手术。使用SPSS进行统计分析。
共确定了166例患者，每组83例。在年龄、种族和性别方面未发现差异。尽管疼痛水平存在细微差异，但总体术后疼痛评分分析并未强烈支持一种技术优于另一种技术。机器人辅助组出院回家而非去SAR的患者数量明显更多，且出院时间也比传统组短。
与传统TKA相比，机器人辅助TKA术后疼痛评分相似。机器人辅助组还表现出其他益处，包括更早出院，并且更有可能出院回家而非去SAR。
