Does Joint Immobilization Following Revision Total Knee Arthroplasty (rTKA) Improve Range of Motion Following Surgery?
Hospital for Special Surgery, New York

INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria2

- Patients undergoing revision TKA of one or both components.
Exclusion Criteria8
- Patients who are undergoing revision TKA for stiffness.
- Patients with occult infection not recognized prior to revision.
- Patients with hinged TKA component reconstructions.
- Patients undergoing revision for liner exchange.
- History of VTE/PE.
- Patients on pre-operative anticoagulation.
- BMI ≥ 40.
- Patients with preoperative opioid use equal to or exceeding 150 Morphine Milligram Equivalents (MMEs)/day within 90 days of revision TKA.

Interventions
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.
Participants will not wear a knee immobilizer and will perform all exercises included in postoperative physical therapy protocol.
