Comparing CCK vs. PS Bearings in Revision Knee Replacement Surgery
This study is looking at two different types of knee replacement parts, called Constrained Condylar (CCK) and Posterior Stabilized (PS) bearings, for people who need a second knee replacement surgery (revision total knee arthroplasty). The goal is to see if one type of bearing leads to better patient satisfaction and surgical outcomes, including how long the new knee lasts. You might be able to join if you are between 18 and 80 years old, need a revision to your femoral (thigh bone) and/or tibial (shin bone) knee components, and it's been at least 6 weeks since your first knee surgery. The study will measure how you feel and your knee's function at 6 weeks, 1 year, and 2 years after your surgery. The current recruitment status is unclear.
- Study design
