Abstract: Total hip arthroplasty (THA) aims to relieve pain, increase hip function and improve quality of life for patients with end- stage osteoarthritis of the hip who do not benefit from non-surgical treatment. Despite constant improvements in prosthetic component design and surgical techniques, prosthetic loosening, wear and dislocation remain the most common complications of a hip replacement procedure. Roentgen Stereophotogrammetric Analysis (RSA) is a highly accurate technique that enables three-di... more
