Early Pain Relief and Function After Posterior Minimally Invasive and Conventional Total Hip Arthroplasty

60 patients undergoing total hip arthroplasty (THA) were randomized to compare minimally invasive and conventional THA. The authors hypothesized that a posterior mini-incision THA will yield better pain relief and functional recovery than the conventional long incision THA. the posterior mini-incision THA resulted in better pain control (p=0.002), earlier discharge from hospital (p=0.003), and better functional outcomes. However, the two groups showed equivalency in clinical results in later follow-ups.
