Association Between Digitally Provided Education and 90-Day Return to Sexual Activity Following Total Knee Arthroplasty: A Randomized Controlled Trial

Abstract

BackgroundContemporary total knee arthroplasty patients have increased expectations of returning to predisease function, including sexual activity (SA). The purpose of this study was to determine whether patients using a digital care management platform (DCMP) were more likely to have a higher rate and frequency of return to SA. MethodsWe conducted an exploratory analysis of a prospective, multicenter, randomized controlled trial that enrolled patients undergoing total knee arthroplasty. A total of 304 patients were randomized to a DCMP (n = 119) providing preoperative and postoperative education regarding return to SA or standard postoperative care (control group; n = 185). Return to SA, assessed via questionnaire, patient-reported outcome measures, Timed Up and Go test, single leg stance, active range of motion and need for manipulation under anesthesia were assessed at 90 days postoperatively. ResultsMore patients in the DCMP group returned to SA compared to control at 90 days (58.4 versus 39.6%, P = .018); however, the control group resumed SA sooner (33.1 versus 42.0 days, P = .023). Patients who returned to SA were younger (61.6 versus 65.9 year), more often men (56 versus 35%) (P < .001), higher performing on the Timed Up and Go and single leg stance tests (P < .001), and had greater active range of motion (P = .007). There were no differences in patient-reported outcome measures or need for manipulation under anesthesia between patients that returned to SA and those who did not. ConclusionsMore patients using a DCMP resumed SA at 90 days; however, patients in the control group returned to SA sooner. Those who returned to SA were younger, possessed greater physical function, and were more often men.
