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 .
Greater prevalence of wound complications requiring reoperation with direct anterior approach total hip arthroplasty.
The purpose of this retrospective study was to compare wound complication rates between primary THAs performed via a posterior or direct anterior approach .  From our prospect i ve outcomes registry , we identified 1288 primary THAs performed via a posterior approach and 505 via a direct anterior approach .  The direct anterior approach result ed in a significantly greater number of wound complications that required reoperation than the posterior approach ( 7/505 ( 1.4 % ) vs. 3/1,288 ( 0.2 % ) , P=0.007 ) . As such , patients should be counseled on the potential increased risk of early wound complications with the direct anterior approach , and future research is needed to determine if alternative closure techniques can reduce the risk of wound complication
