REST-Knee: A Pilot RCT of 72-Hour Knee Immobilization and Pain Outcomes
Postoperative pain following total knee arthroplasty (TKA) is often difficult to manage, particularly with the increasing use of outpatient surgery where patients recover at home. This study aims to evaluate whether wearing a knee extension brace for the first 72 hours after surgery can reduce pain and improve recovery

| Summary | Postoperative pain following total knee arthroplasty (TKA) is often difficult to manage, particularly with the increasing use of outpatient surgery where patients recover at home. This study aims to evaluate whether wearing a knee extension brace for the first 72 hours after surgery can reduce pain and improve recovery. This pilot randomized controlled trial will compare two groups of patients undergoing primary unilateral TKA: one group will wear an extension brace continuously for 72 hours after surgery, while the control group will follow standard care with early mobilization. Participants will be followed for up to 12 months. The primary objective of this pilot study is to assess the feasibility of conducting a larger trial, including recruitment rates, adherence to the intervention, f |
