Official title
A Prospective, Randomized, Controlled Study Comparing A Mobile-Bearing Total Knee System With A Fixed-Bearing Total Knee System In Cemented Total Knee Arthroplasty
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Pain, weakness, instability, and progressive dysfunction are the hallmarks of arthritis of the knee. Total knee replacement may frequently be the only therapeutic intervention to provide adequate improvement in pain and function. Both fixed bearing and mobile bearing knees have a long track record of clinical success. Mobile bearing designs have theoretical advantages of decreased contact stresses on the tibial tray, decreased polyethylene wear, and improved range of motion relative to fixed bearing designs. These theoretical advantages may become especially important in the young patient who requires a knee arthroplasty. This study will attempt to see if there is a clinical difference in outcome between mobile bearing and fixed bearing knee arthroplasties in patients who require total knee replacement.
