机器人辅助与传统人工全膝关节置换术的临床疗效比较研究OA

Objective To compare the clinical efficacy of robotic-assisted total knee arthroplasty(RATKA)versus conventional total knee arthroplasty(TKA)in the treatment of end-stage knee osteoarthritis(KOA).Methods A retrospective analysis was conducted on 56 patients with end-stage KOA between January 2023 and December 2024 at Wuhan Hospital of Integrated Traditional Chinese and Western Medicine Orthopedics.Among them,27 patients underwent RATKA(RATKA group),and 29 underwent conventional TKA(conventional TKA group).Perioperative indicators,including operative time,osteotomy time,intraoperative blood loss,postoperative drainage volume,and hemoglobin difference,were recorded.Radiographic parameters such as hip-knee-ankle angle(HKA)deviation,coronal femoral component angle(CFCA),coronal tibial component angle(CTCA),and posterior tibial slope angle(PTSA)inclination were compared between the two groups preoperatively and at the last postoperative follow-up.Clinical efficacy indicators,including the visual analogue score(VAS),range of motion(ROM),and knee society score(KSS),were evaluated preoperatively and at the final follow-up.Complications during the perioperative and follow-up periods were also recorded.Results All surgeries were successfully completed,with a follow-up period ranging from 6 to 28 months(mean:14.04±5.82 months).No significant differences were observed in the incidence of postoperative complications,intraoperative blood loss,osteotomy time,or postoperative drainage volume between the two groups(P>0.05).However,the operative time was longer in the RATKA group,while the hemoglobin difference was lower compared to the conventional TKA group(P<0.05).Preoperative HKA deviation,CFCA,CTCA,and PTSA showed no significant differences between the two groups(P>0.05).At the final follow-up,HKA deviation significantly decreased in both groups compared to preoperative values,with a greater reduction in the RATKA group(P<0.05).No significant differences were found in CFCA between the two groups postoperatively or compared to preoperative values(P>0.05).Although CTCA showed significant changes postoperatively within each group(P<0.05),no significant differences were observed between the groups(P>0.05).The PTSA was higher in the RATKA group than in the conventional TKA group at the final follow-up(P<0.05).Both groups exhibited significant improvements in VAS score,ROM,and KSS score postoperatively(P<0.05),but no significant differences were found between the groups(P>0.05).Conclusion Compared with traditional total knee arthroplasty(TKA),domestic HURWA robot-assisted TKA is associated with less perioperative blood loss,and can significantly improve the accuracy of lower limb alignment and prosthesis implantation.
