[Objective]To compare the clinical outcomes of anterior approach femoral head replacement for femoral neck fracture with or without capsule suture.[Methods]A retrospective study was conducted on 82 elderly patients who received anterior approach femoral head replacement for femoral neck fractures in our hospital from February 2015 to June 2020.According to preoperative doctor-patient communication,35 patients had capsule sutured,while other 47 patients were unsutured.The documents regarding to perioperative period,follow-up and images were compared between the two groups.[Results]Although the sutured group consumcd significantly longer opera-tive time than the unsutured group[(72.3±10.4)min vs(53.6±8.9)min,P＜0.001],the former proved significantly superior to the latter in terms of intraoperative blood loss[(172.6±24.6)ml as(226.3±32.5)ml,P＜0.001],postoperative ambulation time[(4.2±1.0)days as(5.6±1.7)days,P＜0.001]and hospital stay[(10.3±2.3)days as(12.5±2.4)days,P＜0.001].All patients were followed up for more than 12 months,and the sutured group resume full weight-bearing activity significantly earlier than the unsutured group[(48.3±8.0)days vs(70.4±13.3)days,P＜0.001].Compared with those 6 months after surgery,the pain VAS score significantly decreased(P＜0.05),while SF-36,Harris scores and hip extension-flexion ROM significantly increased in both groups at the latest follow-up(P＜0.05).At all corresponding time points,VAS score and SF-36 score in sutured group were significantly better than those in unsutured group(P＜0.05).As for imaging,the sutured group got significantly less bilateral femur length discrepancy than the unsutured group at the last follow-up(P＜0.05).[Conclusion]Suturing the joint capsule is significantly better than the non-suturing regarding many factors such as intraoperative blood loss,postoperative recovery,pain relief,quality of life improvement and hip function recovery in hemiarthroplasty for femoral neck fracture.
