Summary

This study looked at 192 people aged 50-85 with knee arthritis who needed knee replacement surgery. Half had computer-navigated surgery and half had the traditional technique. The goal was to see if computer guidance helps the new knee last longer, improves function, or reduces complications. Researchers used special X-rays and scans to track implant movement and predict long-term success.
