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 .
Anterolateral minimally invasive total hip arthroplasty: a prospective randomized controlled study with a follow-up of 1 year.
Anterolateral minimally invasive hip surgery ( ALMIS ) is a challenging procedure that is thought to offer a more expedient and a better functional outcome . Seventy-nine patients receiving primary hip arthroplasty were r and omized .  Röttinger ALMIS technique was used for 42 patients , whereas 41 received the st and ard lateral transgluteal Hardinge approach .  Operative time was longer with ALMIS ( P = .000078 ) , whereas blood loss was less ( P = .008 ) . Surgical and postoperative complication rates , morphine consumption , and length and cost of hospitalization were similar . At 1 year , Harris , Postel and Merle d'Aubigné , and Short Form-36v1 scores were similar . Gait analysis revealed similar results . Computed tomographic analysis revealed no significant difference in implant position , heterotopic ossification , and loosening .  Röttinger ALMIS is a valid approach for hip arthroplasty . However , it offers no advantages at 1 year
