About the study

The goal of this study is to evaluate if knee immobilization for 10 days following revision total knee arthroplasty (rTKA) improves knee joint range of motion at 3 months postoperatively compared to standard of care postoperative protocol.

Participants will be assigned to one of two groups.

One group will wear a knee brace that keeps the knee straight for 10 days after surgery and will not perform knee range of motion exercises during that time. The other group will not wear a brace and will follow the standard physical therapy program, including knee range of motion exercises, starting after surgery.

What is being tested

• Knee immobilizer (device)
• No Knee Immobilizer (device)
