Objective To investigate the effectiveness of artificial intelligence(AI)preoperative planning for total hip arthro-plasty(THA).Methods A total of 68 cases of primary unilateral total hip arthroplasty from August 2017 to April 2022 at the au-thor's hospital were retrospectively analyzed and grouped according to different preoperative planning methods.Thirty-five cases with AI preoperative planning were categorized into the observation group,and 33 cases with conventional radiographic preopera-tive planning were categorized into the control group.Surgery time,intraoperative blood loss,accuracy of preoperative planning and post-operative Harris scores of hip function at 1 month,3 months,6 months,1 year,and 2 years were compared between the two groups.Results All patients successfully completed the surgery and received at least 2 years of follow-up,and none of the patients had complications such as loosening of the prosthesis,infection,or fracture.The surgery time and intraoperative blood loss of the observation group were significantly less than those of the control group,and the difference was statistically significant(P<0.05).The accuracy rate of the acetabular component and the femoral component was 65.7%(23/35)and 77.1%(27/35)re-spectively in the observation group,and 33.3%(11/33)and 39.4%(13/33)respectively in the control group;the accuracy rate in the observation group was significantly higher than that in the control group,and the differences were statistically significant(P<0.05).The Harris scores of hip function in the observation group were significantly higher than those in the control group at 1 month,3 months,and 6 months postoperatively,and the difference was statistically significant(P<0.05),while there was no sta-tistically significant difference between the two groups at 1 year and 2 years after surgery(P>0.05).Conclusion AI preopera-tive planning has a high accuracy of prosthesis prediction intotal hip arthroplasty,which can reduce the surgery time and intra-operative blood loss,and is favorable to the early recovery of hip function of the patients,but the effects on the postoperative long-term hip function are not obvious,and further research is still needed.
