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 .
Are clinical and patient assessed outcomes affected by reducing length of hospital stay for total hip arthroplasty?
This prospect i ve observational study investigated the relationship between the length of hospital stay ( LOS ) and outcomes at 3 months for primary total hip arthroplasty for osteoarthritis . Mean length of postoperative stay was 9.5 + /- 2.8 days . Predictors of LOS were patient 's age , sex , and number of comorbidities ; preoperative Charnley scores and Nottingham Health Profile measures ; complications ; and hospital in which surgery took place . LOS was found to have a small negative correlation with outcome . The dominant association with improved outcome was the severity of the patients ' impairment preoperatively . These data suggest that in situations in which adequate rehabilitation and support are available after discharge , a marginal reduction in postoperative LOS -- from the average of 10.3 days observed at 1 hospital to the average of 8 days observed at another -- would not adversely affect the short-term outcome
