Clinical Comparative Analysis of Direct Anterior Approach and Posterolat-eral Approach in Total Hip Arthroplasty
Objective To compare the effect and complications of direct anterior approach(DAA)and posterolateral approach(PLA)for total hip arthroplasty(THA).Methods Clinical data of 80 THA patients treated in Sanming First Hospital Affiliated to Fujian Medical University from January 2022 to December 2023 were retrospectively selected and divided into DAA group(n=43,DAA approach operation)and PLA group(n=37,PLA approach operation)accord-ing to the approach method.The surgical indicators of the two groups were compared,the acetabular prosthesis loca-tions of the two groups were compared by imaging examination 2 days after surgery,the Visual Analogue Scale(VAS)score and the Harris hip function score of the two groups were compared before and after surgery,and the occurrence of complications within 3 months after surgery was recorded.Results The surgical indexes of DAA group were lower than those of PLA group,the difference was statistically significant(P<0.05).VAS and Harris scores in both groups were better than those before surgery at different time points after surgery,and VAS and Harris scores in DAA group were better than those in PLA group,the differences were statistically significant(all P<0.05).2 days after surgery,there was no significant difference in the anterior inclination and abduction Angle of acetabular prosthesis between the two groups(all P>0.05).The safe zone placement rate in DAA group was 95.35%(41/43),which was higher than that in PLA group 75.68%(28/37),and the difference was statistically significant(χ2=6.490,P<0.05).Three months after surgery,there was no significant difference in the total incidence of complications between the two groups(P>0.05).Conclusion Compared with PLA approach,DAA approach can reduce surgical trauma,relieve postoperative pain,pro-mote the recovery of hip function and speed up the postoperative recovery process.
