Abstract:
Objective To explore the application effect of absorbable thread anchors in the reconstruc-tion of short external rotation muscle groups and posterior joint capsules in total hip arthroplasty(THA).Methods The clinical data of the patients who underwent THA in Guizhou Provincial People's Hospital from September 2022 to June 2023 were analyzed.The observation group(n=40)adopted the absorbable wire an-chors to reconstruct the short external rotation muscle group,and the short external rotation muscle group and joint capsule were fixed to the the greater trochanter fossa of the femur.The control group(n=40)a-dopted the conventional suture method,using non-absorbable sutures to suture and fix the short external rota-tor muscle group at the insertion point of the great trochanter of the gluteus tendon.The operation time,intra-operative blood loss amount and incision length were recorded.The Harris Hip Score(HHS)of the patients,the internal and external rotation angles of the hip joint,the unarmed muscle strength test(MMT)grade of the external rotation muscle group in postoperative 12 months,and the incidence rate of dislocation within postoperative 12 months were evaluated in postoperative 3,6,and 12 months.Results All 80 patients success-fully completed the THA,and all patients were followed up for at least 12 months.In postoperative 3,6 and 12 months,the HHS score of the observation group was higher than that of the control group,and the difference was statistically significant(P<0.05).In postoperative 12 months,the internal and external rotation angles of the hip joint in the observation group were greater than those in the control group,and the difference was statistically significant(P<0.05).However,in postoperative 3 and 6 months,there was no statistically signif-icant difference in the internal and external rotation angles of the hip joint between the two groups(P>0.05).In postoperative 12 months,the MMT grade of the observation group was superior to that of the con-trol group,and the difference was statistically significant(P<0.05).No dislocation of the hip joint occurred within postoperative 12 months in the two groups.Conclusion The use of absorbable wire anchors to recon-struct the short external rotation muscle group and posterior joint capsule during THA could enhance posteri-or stability,promote the recovery of early hip joint function and external rotation muscle strength in the pa-tients,and accelerate their recovery.
