Efficacy of robot-assisted total knee arthroplasty in treating severe varus deformity knee osteoarthritis
摘要
Abstract
Objective To explore the application value of robotic-assisted total knee arthroplasty(RATKA)in the treatment of severe varus deformity in osteoarthritis of the knee and to evaluate its postoperative effects and impact on lower limb alignment.Methods A retrospective analysis was performed on 58 patients who underwent knee arthroplasty at Wuhan Pu'ai Hospital,Tongji Medical College,between February 2023 and October 2024.Among them,31 patients underwent robotic-assisted total knee arthroplasty(RATKA)using the TiRobot system,and 27 patients underwent conventional TKA.Perioperative outcomes,including postoperative hospital stay,operative time,incision length,intraoperative blood loss,drainage volume,and hemoglobin changes were compared.Preoperative and postoperative evaluations of hip-knee-ankle angle(HKA),mechanical lateral distal femur angle(mLDFA),mechanical medial proximal tibial angle(mMPTA),and lateral tibial component angle(LTC)were analyzed.Additionally,Knee Society Score(KSS),visual analogue scale(VAS),forgotten joint score(FJS),and range of motion(ROM)were assessed preoperatively and at the final follow-up.Results All patients in this study were followed up for 3 to 26 months,with a mean follow-up of(12.6±6.5)months.The surgical duration in the robotic group was significantly longer than that in the conventional group,and the incision length was longer(P<0.05).However,there were no significant differences in intraoperative blood loss,postoperative hospital stay,or drainage volume between the two groups(P>0.05).Postoperative HKA was significantly lower in the robotic group than in the conventional group(P<0.05).The proportion of patients rated as"excellent"for postoperative HKA deviation,mLDFA,and mMPTA was significantly higher in the robotic group(P<0.05),while the proportion rated as"poor"was significantly lower(P<0.05).The postoperative LTC angle in the robotic group was closer to the ideal value of 3°,with a statistically significant difference compared to the conventional group(P<0.05).Postoperative KSS scores,VAS scores and ROM improved in both groups compared to the preoperative period,but there were no significant differences between the groups(P>0.05).Conclusion RATKA can significantly improve the accuracy of lower limb alignment and achieve better imaging results in the treatment of patients with severe varus deformity of the knee.Additionally,RATKA can reduce the surgeon's workload in preoperative planning and intraoperative procedures,improve the precision and stability of the surgery,and demonstrate high clinical application value.关键词
