Moreover , postoperative complications ( eg , dislocation and revision surgery ) were less frequent in the CM group than in the RA group .
Conclusion Compared with the CM approach , the RA approach yields better radiological outcomes and fewer intraoperative complications in THA , but similar functional scores
Abstract Background Several studies have compared robotics‐assisted ( RA ) and conventional manual ( CM ) approaches for total hip arthroplasty ( THA ) , but their results are controversial .
Robot-assisted primary cementless total hip arthroplasty with a short femoral stem: a prospective randomized short-term outcome study
Abstract Background : Recently , two topical issues in total hip arthroplasty ( THA ) have been robot-assisted surgery and use of a short stem . The purpose of this study was to evaluate the effects of robotic milling on the accuracy of short femoral stem positioning and on the short-term clinical outcome in THA using a prospect i ve , r and omized design . Methods : We r and omized 54 patients into two groups , either robotic milling group or manual rasping group .  The patients were assessed clinical ly and radiographically at 8 weeks , 5 months , 12 months , and 24 months . Results : Robotic milling group had a significantly longer operation time , requiring on average 8.9 min for registration and 11.2 min for milling . On the other h and , robotic milling group showed superior results in terms of stem alignment and leg length e quality . Two intraoperative femoral fractures occurred only in manual rasping group . Harris hip scores and WOMAC scores at 24 months postoperatively were similar in both groups . No complications including stem loosening , infection , nerve palsy , or dislocation were encountered in either group during the follow-up period . Conclusions : The present study suggested that robot-assisted short stem THA could increase the accuracy of stem alignment , improve leg length e quality , and help reduce the risk of intraoperative femoral fracture as compared with manual rasping . However , the clinical outcome scores did not differ between the two groups at the time of short-term follow-up . Long-term follow-up is needed to determine whether there will be a long-term clinical relevance of robot-assisted implantation of short femoral stems in THA
Moreover , postoperative complications ( eg , dislocation and revision surgery ) were less frequent in the CM group than in the RA group .
