Abstract: Objective: To investigate the effects of the anterolateral and posterolateral approaches in hip replacement surgery on the postoperative recovery.Methods: Sixty patients treated with hip replacement surgery were randomly divided into the anterolateral group and posterolateral group(30 cases each group).The assessment before and after treatment,and comprehensive recovery training in two groups were implemented.The ability of daily movement,VAS score and perimeter measurement in two groups were observed before and after hip replacement surgery,and after 3 and 10 days of rehabilitation treatment.Results: The differences of the activities of daily living(ADL) between two groups treated with hip replacement surgery after 3 and 10 days of rehabilitation treatment were statistically significant(P < 0.01).The difference of the VAS score between two groups treated with hip replacement surgery after 3 days of rehabilitation treatment was statistically significant(P < 0.01).The differences of the circumference measurement between two groups treated with hip replacement surgery after 3 and 10 days of rehabilitation treatment were not statistically significant(P > 0.01).Conclusions: The effect of different surgery approaches on the ability of daily movement of postoperative patients treated with hip replacement surgery is small.Compared with the posterolateral group,the improvement time of the pain and swelling in anterolateral group after surgery shorten significantly.
