This study reports the five-year functional outcomes from a prospective cohort study comparing robotic-arm assisted total knee arthroplasty (RO TKA) versus conventional manual total knee arthroplasty (CO TKA).
This prospective single-surgeon study included 120 patients with symptomatic end-stage knee arthritis undergoing primary TKA. This included 60 consecutive patients undergoing CO TKA followed by 60 consecutive patients undergoing RO TKA using a semi-automated robotic device. Study patients were reviewed at one, two, and five years after surgery and the following outcomes recorded: The University of California at Los Angeles activity-level (UCLA), Knee Society Score (KSS), Oxford Knee Score (OKS) Forgotten Joint Score (FJS), and any complications.
There were no statistical differences between RO TKA and CO TKA in the median UCLA score (p = N.S), median KSS (p = N.S), and median OKS (p = N.S) at five-year follow-up. RO-TKA was associated with statistically significant improvements in the FJS at one (p = 0.001), two (p = 0.003), and five (p = 0.025) years of follow-up compared with CO TKA. There was no statistical difference in the incidence of knee stiffness requiring manipulation under anesthesia between the two treatment groups (p = N.S).
Patients in both treatment groups had excellent functional outcomes with comparable patient reported outcomes at five-year follow-up. RO TKA was associated with statistically significant improvements in the FJS compared with CO TKA, but these differences did not reach the minimal clinically important difference at any follow-up interval. There was no overall difference in complications between the two treatment groups at five-year follow-up.

本研究报告了一项前瞻性队列研究的五年功能结果，该研究比较了机器人手臂辅助全膝关节置换术（RO TKA）与传统手动全膝关节置换术（CO TKA）。
这项前瞻性单医生研究纳入了120例有症状的终末期膝关节炎患者，他们接受了初次全膝关节置换术。其中包括60例连续接受CO TKA的患者，随后是60例连续使用半自动机器人设备接受RO TKA的患者。对研究患者在术后1年、2年和5年进行复查，并记录以下结果：加利福尼亚大学洛杉矶分校活动水平（UCLA）、膝关节协会评分（KSS）、牛津膝关节评分（OKS）、遗忘关节评分（FJS）以及任何并发症。
在五年随访时，RO TKA和CO TKA在UCLA评分中位数（p = 无统计学意义）、KSS中位数（p = 无统计学意义）和OKS中位数（p = 无统计学意义）方面无统计学差异。与CO TKA相比，RO-TKA在随访1年（p = 0.001）、2年（p = 0.003）和5年（p = 0.025）时FJS有统计学显著改善。两个治疗组之间在需要麻醉下手法治疗的膝关节僵硬发生率方面无统计学差异（p = 无统计学意义）。
两个治疗组的患者在五年随访时均有良好的功能结果，患者报告的结果相当。与CO TKA相比，RO TKA在FJS方面有统计学显著改善，但这些差异在任何随访间隔均未达到最小临床重要差异。在五年随访时，两个治疗组之间并发症无总体差异。
