Knee replacement showdown: fixed vs. mobile bearing – which is better?
NCT ID NCT00435357
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of total knee replacements in 160 patients with medial knee arthritis. One group received a fixed-bearing implant, the other a mobile-bearing implant. Researchers measured knee function and X-ray results to see if one design leads to better outcomes.
