Patients’ Perceptions of Remote Monitoring and App-Based Rehabilitation Programs: A Comparison of Total Hip and Knee Arthroplasty

Background: Remote monitoring rehabilitation programs are new technologies growing in popularity for patients undergoing lower extremity total joint arthroplasty. The purpose of this study was to assess the patients' perceptions of these technologies. Methods: Patients who underwent total hip arthroplasty (THA), total knee arthroplasty arthroplasty (TKA), and unicompartmental knee arthroplasty (UKA) from September 2020 to February 2022, and participated in a clinical study utilizing remote monitoring and an app-based rehabilitation program were given a questionnaire 3 months postoperatively to assess their perceptions of these technologies. There were 166 patients who completed the survey (42 THA; 106 TKA; 18 UKA). Results: There were 92% of patients who found the technology easy to use. A majority of patients felt the technologies motivated them. The TKA/UKA patients felt more strongly that these technologies allowed the surgeon to monitor their recovery closely (81.9% versus 65.9%; P = .009). There were 85% of THA patients and 94.5% of TKA/UKA patients recommended these technologies. The THA patients felt more strongly that digital rehabilitation could completely replace in-person physical therapy compared to TKA/UKA patients (85.4% versus 41.3%; P < .001). A majority (83%) of patients recommended a combination of inpatient and technology-assisted rehabilitation (THA 90.2%; 84.4% TKA/UKA). Conclusion: The THA and TKA/UKA patients found remote monitoring rehabilitation easy to use, increased motivation, and recommend it to other patients undergoing lower extremity arthroplasty. They recommend a combination of technology and in-person rehabilitation postoperatively. The THA patients felt these technologies could replace in-person rehabilitation programs. Level of Evidence: IV.
