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 .
Patient-reported outcome after total hip arthroplasty: comparison between lateral and posterior approach
Background and purpose — Criticism of the lateral approach ( LA ) for hip arthroplasty is mainly based on the risk of poor patient-reported outcomes compared to the posterior approach ( PA ) . However , there have been no controlled studies comparing patient-reported outcomes between them . In this r and omized controlled trial , we tested the hypothesis that patient-reported outcomes are better in patients who have undergone total hip arthroplasty ( THA ) with PA  than in those who have undergone THA with LA , 12 months postoperatively . Patients and methods — 80 patients with hip osteoarthritis ( mean age 61 years ) were r and omized to THA  using  PA or the modified direct LA . We recorded outcome measures preoperatively and 3 , 6 , and 12 months postoperatively using the Hip Disability and Osteoarthritis Outcome Score – Physical Function Short Form ( HOOS-PS ) as the primary outcome . Secondary outcomes were HOOS-Pain , HOOS- Quality -Of-Life , EQ-5D , UCLA Activity Score , and limping . Results — We found no statistically significant difference in the improvements in HOOS-PS between the treatment groups at 12-month follow-up . All secondary outcomes showed similar results except for limping , where PA patients improved significantly more than LA patients . Interpretation — Contrary to our hypothesis , patients treated with PA did not improve more than patients treated with LA regarding physical function , pain , physical activity , and quality of life 12 months postoperatively . However , limping was more pronounced in the LA patients
