The posterolateral approach reported the lowest value for the surgical duration .
The posterolateral approach reported the shortest hospitalization length .
The posterolateral approach reported shorter surgical duration and hospitalization length .
Concerning the analysis of total estimated blood loss , no significant result was obtained .
Despite the numerous studies , there is no consensus concerning the best approach for  total hip arthroplasty ( THA )  , and debates are ongoing .
The purpose of this study was to perform a Bayesian network meta- analysis ( NMA ) comparing several approaches for primary THA .
The focus was on peri-operative outcomes : surgical duration , total estimated blood loss , and length of the hospitalization .
Prospective randomized study of direct anterior vs postero-lateral approach for total hip arthroplasty.
Benefits of a direct anterior approach ( DAA ) versus a posterior-lateral ( PA ) approach to THA were assessed in a single-surgeon , IRB-approved , prospect i ve , r and omized clinical study . Subjects ( 43 DAA and 44 PA ) were evaluated at 6 weeks , and 3 , 6 and 12 months . The primary end point was ability to climb stairs normally and walk unlimited at each time point . Secondary end points included assessment by several outcome instruments . DAA subjects performed better during the immediate post-operative period ; they had lower VAS pain scores on the first post-operative day , more subjects climbing stairs normally and walking unlimited at 6 weeks , and higher HOOS Symptoms scores at 3 months . There were no significant differences between groups at later time points . Findings confirm previous reports of benefits of DAA versus PA in early post-operative phases
