Comparison Of Direct Anterior Approach And Posterolateral Approach In Total Hip Arthroplasty:Earlier Function Of Balance And Proprioception

Objective To compare earlier function of balance and proprioception in patients between direct anterior approach(DAA)and posterolateral approach(PLA)for the total hip arthroplasty(THA)approaches.Methods Two hundred and fifteen cases(215 hips)treated with unilateral total hip arthroplasty in our hospital from March 2016 to June 2018 were recruited.The patients were divided by surgical approach,the DAA group and PLA group.DAA group(study group)contain 116 cases with average age of 55.28 + 5.66 years;PLA group(control group)contain 99 cases with average age of 56.65±5.82 years.The duration of operation and intraoperative blood loss were compared between two groups.The changes of the Berg Balance Scale(BBS)and joint position sense(JPS)at different time before and after surgery were recorded.Results The operation duration and intraoperative blood loss of the study group were not statistically different from those of the control group(P>0.05).The difference of preoperative function of balance and proprioception between the two groups was not statistically significant(P>0.05).One months after operation,the function of balance and proprioception of the study group was higher than that of the control group(P<0.05).The balance function and proprioception of the patients in the study group were significantly lower than those before operation,with statistically significant differences(P < 0.05).Conclusion The present study show that THA can significantly affect patients' function of balance and proprioception,while using direct anterior approach in THA provides significant benefits for patients in terms of functional balance and proprioception in the early stage postoperatively compared to using posterolateral approach.
