Abstract:
Objective To compare short-term clinical outcomes and patient satisfaction between robotic-assisted total knee arthroplasty(TKA)and conventional TKA.Methods A retrospective analysis was conducted on data of 93 patients who underwent primary unilateral TKA for knee osteoarthritis from June 2022 to April 2023.Among them,46 patients underwent Mako robot-assisted TKA(robot group)and 47 patients underwent traditional manual TKA(traditional group).There was no statistical difference in general data between the two groups(P＞0.05).Follow-up data were collected to compare the differences in surgical indicators,postoperative pain,range of motion(ROM),Hospital for Special Surgery(HSS)score,and Forgotten Joint Score(FJS)between the two groups.Results The operation time of the robotic group was longer than that of the traditional group[(105.8±26.7)min vs.(77.0±14.9)min,P＜0.001].There were no significant differences in total blood loss,hip-knee-ankle(HKA)angle deviation value and deviation rate(HKA angle＞3°)between the two groups at 3 days after surgery(P＞0.05).The robotic group had lower Visual Analogue Scale(VAS)scores for pain than the traditional group at 3 days,2 weeks,and 6 months after surgery(P＜0.001,P＜0.001,P=0.021),and had better knee joint ROM at 3 days,2 weeks,and 3 months after surgery(P＜0.001,P=0.011,P＜0.001).The HSS score(P=0.001)and FJS score(P＜0.001)of the robotic group were better than those of the traditional group at 6 months after surgery.Conclusion Compared with conventional TKA,robot assisted TKA has milder early pain,better mobility,and higher overall postoperative satisfaction.
