Operative time and blood loss were significantly reduced in the mini-incision group for studies with the posterior or posterolateral approach .
Concerning postoperative complications , there were no significant differences between the two groups with no significant heterogeneity .
No differences were observed between the two groups for Harris hip score and radiographic results except for cup anterversion .

The purpose of this study was to compare the operative outcome between mini and st and ard incisions in total hip arthroplasty ( THA ) .
High- quality studies are required to compare the outcomes of these two procedures .ResuméLe but de cette étude est de comparer le devenir opératoire des patients ayant bénéficié d'une prothèse totale de hanche par voie  mini-invasive ou par incision st and ard .
Minimally invasive total hip arthroplasty: a prospective randomized study.
Patients without prior hip surgery and body mass index lower than 30 undergoing primary total hip arthroplasty were eligible to participate in a r and omized prospect i ve study comparing a minimally invasive with a st and ard approach . The patients were r and omized  to receive incisions  of 8 cm ( group A , n = 28 ) or 15 cm ( group B , n = 32 ) . The groups were similar demographically . Patients in group A had significantly less intraoperative blood loss ( P < .003 ) and less total blood loss ( P < .009 ) . Fewer patients in group A limped at 6 weeks ( P < .04 ) . Operative time , transfusion requirements , narcotic usage , length of hospital stay , achievement of rehabilitation milestones , cane usage , and complications were similar in both groups . There was no difference between the groups at 1- and 2-year follow-up . Compared with a st and ard incision , patients who underwent a minimally invasive total hip arthroplasty demonstrated decreased blood loss and limped less at 6-week follow-up
