Interventions

• Knee immobilizer — DEVICE
  Participants will wear a knee immobilizer brace for 10 days postoperatively and exclude knee range of motion exercises from postoperative physical therapy protocol during this period. They will resume all standard postoperative protocol after this period.
• No Knee Immobilizer — DEVICE
  Participants will not wear a knee immobilizer and will perform all exercises included in postoperative physical therapy protocol.

Study Details

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.
