Comparing different artificial knees for total knee replacement surgery
Part of Bones, joints & muscles clinical trials.
This trial is for people with severe arthritis in both knees who need knee replacement surgery. It compares different types of artificial knee joints to see which one works better.
Summary written for real people, not researchers, by Clin2.

- You are between 45 and 80 years old
- Your weight gives a BMI under 35 (a measure of weight relative to height)

- The inward bend of your knee is less than 15 degrees
- A key ligament at the back of your knee (the PCL) is healthy and intact
- You have not had any surgery on your knee ligaments or bones before
- Your knee can bend at least 90 degrees, and it is not stuck in a bent position when you try to straighten it
