ClinConnect Summary

This clinical trial is studying how well two types of knee implants—the MicroPort Medial Pivot and DePuy Attune posterior cruciate retaining (PCR) total knee arthroplasties—perform in real-life movement. Researchers want to understand how these implants work while people go about their daily activities, such as stepping up and doing deep knee bends. Dr. Russell Nevins from the Nevada Orthopedic & Spine Center will lead this study, which is looking for participants who are at least 6 months post-surgery and have had one of the two knee implants mentioned.

To be eligible for this study, participants should be between the ages of 65 to 74 and must have been evaluated as successful in their recovery by their surgeon. They should also be able to complete certain movements and be willing to sign a consent form to join the study. However, people who are pregnant, do not have one of the specified knee implants, cannot perform the required activities, or do not speak English will not be able to participate. The trial is currently not recruiting, but if you meet the criteria, it could be an opportunity to help researchers learn more about knee implants and their effectiveness.
