Importance of hip capsular repair in total hip arthroplasty (THA) via the posterior lateral approach: a five year retrospective cohort study.

Capsular repair during posterior-lateral THA improves postoperative hip function and mobility while reducing dislocation rates, blood loss, pain, inflammation, and economic burden. Patients with rheumatoid arthritis, epilepsy, or sarcopenia require individualized planning and enhanced postoperative care to minimize complications.
