First seen Nov 01, 2025 · Last updated Jun 06, 2026 · Updated 28 times

Summary

This study looks at two types of knee implants for people with severe knee arthritis. One type uses bone cement to hold the implant in place, the other does not. Researchers want to see which implant stays fixed better over 5 years. About 70 people will take part, and the goal is to improve long-term outcomes for knee replacement surgery.
