Grip on Knee OA: distraction vs surgery
Part of Bones, joints & muscles clinical trials.
This trial compares two treatments for severe knee osteoarthritis that hasn't gotten better with other care: knee joint distraction (using an external frame to gently pull the joint apart, allowing healing) versus knee replacement surgery. It aims to see which is better for pain relief and preserving the knee.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You have knee osteoarthritis diagnosed by a doctor, with moderate to severe joint damage on X-ray (grade 2 or higher).
- Your knee pain has lasted a long time and hasn't improved enough with other treatments like physical therapy or surgery.
- You need to be able to wear and take care of an external frame (like a brace with pins) on your leg for 6 weeks, and understand that full improvement can take months after the frame is removed.

This study compares different types of artificial knee replacements to see which ones work better and last longer over time. Researchers will track your recovery, pain relief, and how well your new knee functions for years after surgery.
This study compares two types of osteotomy (bone-cutting and realignment surgeries) for people with knee arthritis that affects only the inner side of the knee and causes a bow-legged deformity. The goal is to find which surgery works better and has fewer complications.
This trial tests a new brace that gently separates the bones in your knee joint to relieve pressure. It is for people with arthritis on the inner or outer side of their knee who have moderate pain and meet specific health requirements.
This study tests a new, non-invasive device used during knee surgery to repair a torn meniscus. It may help your surgeon perform the procedure more safely and effectively.
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.
