Comparing two knee implants in total knee replacement
Part of Bones, joints & muscles clinical trials.
This study compares two types of knee implants (SpheriKA and Origin) used in total knee replacement surgery with a specific alignment technique. The goal is to see which one may lead to better outcomes for patients needing a first knee replacement.

This trial tests two different ways of aligning the new knee joint during a total knee replacement. It aims to see which method gives better results for patients like you.
This study compares two different techniques (mechanical alignment vs. kinematic alignment) used during knee replacement surgery with a special knee system. It aims to see which technique leads to better results for patients.
This study compares a new plastic-and-metal knee implant to a standard metal one for people with severe knee arthritis. If you need a total knee replacement and your knee is not too bent or twisted, you may be a candidate.
This study compares two designs of knee replacement implants to see how they affect walking, function, and outcomes after surgery. You may be randomly assigned to one of the implant types used for your specific, approved knee replacement.
This trial is for adults having their first knee replacement surgery. It tests a special part (tibial extension) of a common knee implant system. Researchers will follow participants over time to see how well it works.
