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 .
Learning curve in tissue sparing total hip replacement: comparison between different approaches
Background The tissue sparing surgery ( TSS ) concept means not only smaller incisions but also less tissue disruption , allowing decreased blood loss and improved function . However , TSS techniques can result in more complications related to the learning curve . The aim of this study was to compare the learning curve of an experienced surgeon with different TSS approaches for total hip replacement ( THR ) from a clinical and surgical point of view , focussing especially on complications related to the use of different geometric stems . Material s and methods Sixty patients scheduled to be operated for a primary THR were enrolled in the study and were r and omly assigned to surgery by one of three different TSS approaches : lateral with mini incision ( group A ) , minimally invasive anterior ( group B ) and minimally invasive antero-lateral ( group C ) . Results from the three TSS groups were compared with a control group of 149 patients ( group D ) . Results Our results reveal significantly reduced blood loss in the TSS groups compared with the control group , with no differences between the TSS groups . We found better early functional scores in the two minimally invasive groups ( anterior and anterolateral ) , and a lower rate of complications with the antero-lateral TSS approach . Conclusion The antero-lateral TSS approach seems to be safer and less dem and ing than st and ard THR surgery , and is suitable for use with different stems
