Piriformis-Sparing Minimally Invasive Versus the Standard Posterior Approach for Total Hip Arthroplasty: A 10-Year Follow-Up of a Randomized Control Trial.

Background: Despite the popularity of minimally invasive approaches in total hip arthroplasty, studies regarding their impact on soft tissues and long-term benefits are lacking. This study aims to compare the 10-year functional outcome of the piriformis-sparing minimally invasive approach to the standard posterior approach for total hip arthroplasty surgery.

Methods: Hundred patients were randomized, 48 patients to the piriformis-sparing approach and 52 to the standard approach.
