Primary total hip arthroplasty (THA) is a commonly used routine treatment for hip diseases for example osteonecrosis of the femoral head, developmental dysplasia of hips, femoral neck fractures, hip OA, ankylosed hip, etc. As described in this analysis, the approach of posterior capsule repair in total hip arthroplasty had a lower complication rate along with better functional outcomes.

Earlier studies have suggested that posterior capsule repair group offers better clinical outcomes in primary THA. This systematic review and meta-analysis aimed to assess the post-operative outcomes between the 2 procedures i.e. in patients with posterior capsule repair and in those without the posterior capsule repair.

A systematic search was done on EMBASE, MEDLINE, and, Cochrane Library. Before presenting the manuscript, the literatures were re-searched again, comprising the articles which directly compared the associated post-operative outcomes of both the groups.

This meta-analysis comprised of 8 comparative studies. A lesser dislocation rate, higher Harris hip score (HHS), and even less post-operative bleeding volume was observed in the posterior capsule repair group as compared to the unrepaired posterior capsule group. No significant difference in range of motion (ROM) was observed.

During primary THA, fixing the posterior capsule during primary THA offers improved functional results, less dislocation rate, and a reduced amount of blood loss.
