A dynamic knee extension device improves flexion contracture before total knee arthroplasty: a randomized controlled trial

This study evaluates a dynamic extension brace that may help improve extension and decrease the rate of postoperative FC. Methods: This study was a prospective randomized controlled trial of 101 patients with a FC of ≥10 degrees scheduled to undergo TKA. Primary outcome was change in maximal active extension during the perioperative period; secondary outcomes were patient-reported outcomes. Data were collected at enrollment, preoperative appointments, and 2-week postoperative appointments. Chi-squared, t tests and repeated measures analysis of variance (ANOVA) were used to evaluate the results between and within groups. Results: Fifty-five patients were in the control group and 46 in the experimental group. The mean FC in the experimental group was significantly worse at enrollment (14.22 degrees vs. 15.76 degrees, P=0.049), but improved by the preoperative appointment (15.76 degrees to 12.52 degrees, P
