This study compared two different surgical alignment techniques used during total knee replacement for osteoarthritis. Fifty-two patients were randomly assigned to receive either a 'neutral mechanical' alignment or an 'anatomic' alignment of their new knee implant. Researchers tr…

This study compared two different hip replacement implants for people with severe hip arthritis. Researchers followed 56 patients for two years after surgery to see if a newer implant provides equal or better stability and results compared to an older, more established model. The…

This study continued tracking 82 people who received specific hip replacement implants to see how well the implants stayed in place over two years. Researchers measured tiny movements of the artificial hip socket using special X-ray analysis and checked how patients were doing wi…

This study followed 64 patients with hip osteoarthritis who received the ACTIS hip replacement implant. Researchers used special X-ray imaging to measure how much the implant settled into the bone over 2 years after surgery. They compared three different surgical approaches and t…
