    [目的] 比较机器人ARTHROBOT辅助全髋置换术(rTHA)与传统手工全髋置换术(mTHA)的早期效果。[方法] 回顾性收集2022年4月—2022年11月我院行THA的58例患者的临床资料,根据手术方式的不同将患者分为两组,其中rTHA组28例、mTHA组30例,对比两组围手术期、随访及影像学资料。[结果] 两组患者均手术顺利,未见术中并发症。rTHA组手术时间、切口总长度显著大于mTHA组(P<0.05)。两组术中失血量、切口愈合等级及住院时间差异无统计学意义(P>0.05),rTHA组治疗费用较高(P<0.05)。两组完全负重时间无统计学差异(P>0.05),随访期间,rTHA组术后1个月、末次随访Harris评分及术后6个月髋内-外旋ROM均显著大于mTHA组(P<0.05),术后1个月、6个月、末次随访VAS评分及髋伸-屈ROM,术后6个月Harris 评分,术后1个月和末次随访时髋内-外旋ROM差异均无统计学意义(P>0.05)。随时间推移,两组患者 VAS 评分显著减小(P<0.05),而 Harris 评分、髋伸-屈ROM、髋内-外旋ROM均显著增加(P<0.05)。rTHA组术后LLD、双侧FOD差值、双侧AOD差值、双侧COD差值均显著低于mTHA组(P<0.05),而两组的AAA和AA差异无统计学意义(P>0.05)。以Lewinnek 安全区为标准,rTHA组安全区内病例数占比显著高于mTHA组(P<0.05)。[结论] 机器人ARTHROBOT辅助THA使假体植入更精准,髋臼杯置入安全区的比例更高,能更好恢复患髋偏心距,有利于减少LLD,疗效更佳。


    [Objective] To compare the early effects of robot ARTHROBOT-assisted total hip arthroplasty (rTHA) and traditional manual total hip arthroplasty (mTHA).[Methods] The clinical data of 58 patients who underwent THA in our hospital from April 2022 to November 2022 were collected retrospectively. According to the different operation methods, the patients were divided into two groups: rTHA group (n = 28) and mTHA group (n = 30). The perioperative period, follow-up and imaging data of the two groups were compared.[Results] The operation was successful in both groups, and no intraoperative complications were found. The operation time and the total length of incision in rTHA group were significantly longer than those in mTHA group(P < 0.05). There was no significant difference in intraoperative blood loss, wound healing grade and hospitalization time between the two groups(P > 0.05), but the treatment cost was higher in rTHA group(P < 0.05). There was no significant difference in complete weight-bearing time between the two groups (P > 0.05). During the follow-up period, the Harris score at 1 month and the last follow-up and the hip internal-external rotation ROM at 6 months after operation in the rTHA group were significantly higher than those in the mTHA group(P < 0.05). There was no significant difference in VAS score and hip extension-flexion ROM at 1 month, 6 months and the last follow-up, Harris score at 6 months after operation, and hip internal-external rotation ROM at 1 month and the last follow-up(P > 0.05). With the passage of time, the VAS score decreased significantly, while the Harris score, hip extension-flexion ROM and hip internal-external rotation ROM increased significantly in both groups(P < 0.05). The postoperative LLD, bilateral FOD difference, bilateral AOD difference and bilateral COD difference in the rTHA group were significantly lower than those in the mTHA group(P < 0.05), but there was no significant difference in AAA and AA between the two groups(P > 0.05). According to the standard of Lewinnek safe zone, the proportion of cases in rTHA group was significantly higher than that in mTHA group(P < 0.05). [Conclusion] Robotic ARTHROBOT-assisted total hip replacement makes prosthesis implantation more precise, and the proportion of acetabular cup placement in the safe zone is higher, which can better restore the hip offset of the affected hip, help reduce LLD, and achieve better results.
