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 .
Neither pre-operative education or a minimally invasive procedure have any influence on the recovery time after total hip replacement
Purpose The purpose of this study was to evaluate pre-operative education versus no education and mini-invasive surgery versus st and ard surgery to reach complete independence . Methods We conducted a four-arm r and omized controlled trial of 209 patients . The primary outcome criterion was the time to reach complete functional independence . Secondary outcomes included the operative time , the estimated total blood loss , the pain level , the dose of morphine , and the time to discharge . Results There was no significant effect of either education ( HR : 1.1 ; P = 0.77 ) or mini-invasive surgery ( HR : 1.0 ; 95 % ; P = 0.96 ) on the time to reach complete independence . The mini-invasive surgery group significantly reduced the total estimated blood loss ( P = 0.0035 ) and decreased the dose of morphine necessary for titration in the recovery ( P = 0.035 ) . Conclusions Neither pre-operative education nor mini-invasive surgery reduces the time to reach complete functional independence .  Mini-invasive surgery significantly reduces blood loss and the need for morphine consumption
