Telemedicine is the delivery of healthcare from a remote location using integrated computer/communication technology. This systematic review aims to explore evidence for telemedicine in orthopaedics to determine its advantages, validity, effectiveness and utilisation particularly during our current pandemic where patient contact is limited.

Databases of PubMed, Scopus and CINHAL were systematically searched and articles were included if they involved any form of telephone or video consultation in an orthopaedic population. Findings were synthesised into four themes: patient/clinician satisfaction, accuracy and validity of examination, safety and patient outcomes and cost effectiveness. Quality assessment was undertaken using Cochrane and Joanna Briggs Institute appraisal tools.

Twenty studies were included consisting of nine RCTs across numerous orthopaedic subspecialties including fracture care, elective orthopaedics and oncology. Studies revealed high patient satisfaction with telemedicine for convenience, less waiting and travelling time. Telemedicine was cost effective particularly if patients had to travel long distances, required hospital transport or time off work. No clinically significant differences were found in patient examination nor measurement of patient reported outcome measures. Telemedicine was reported to be a safe method of consultation. However, studies were of variable methodological quality with selection bias.

In conclusion, evidence suggests that telemedicine in orthopaedics can be safe, cost effective, valid in clinical assessment with high patient/clinician satisfaction. Further work with high quality RCTs is required to elucidate long term outcomes. This systematic review presents up-to-date evidence on the use of telemedicine and provides data for organisations considering its use in the current COVID-19 pandemic and beyond.

Introduction. The COVID-19 pandemic led to a swift adoption of telehealth in orthopedic surgery. The purpose of this study was to analyze patient and surgeon satisfaction with a rapid expansion of telehealth use during COVID-19 pandemic within the division of adult reconstructive surgery at a major urban academic hospital. Methods. 334 hip and knee arthroplasty patients who completed a telemedicine visit from March 30th, 2020 through April 30th, 2020 were sent a 14-question survey. Eight adult reconstructive surgeons who used telemedicine were sent a separate 14-question survey at the end of the study period. Factors influencing patient satisfaction were determined using univariate and multivariate ordinal logistic regression modeling. Results. 20.4% of patients (68/334) and 100% of surgeons (8/8) completed the surveys. Patients were on average “Satisfied” with their telemedicine visits (4.10/5.00 ± 0.98), 54.4% considered themselves high-risk for COVID-19 complications, and 27.9% reported that they preferred future visits to be conducted using telemedicine for reasons unrelated to COVID-19. Multivariate ordinal logistic regression modeling revealed that patients reported higher satisfaction if their surgeon effectively responded to their questions/concerns (OR 3.977; 95% CI 1.260 to 13.190, p=0.019) and if their visit had higher audiovisual quality (OR 2.46; 95% CI 1.052 to 6.219, p=0.042). Surgeons were “Satisfied” with their telemedicine experience (3.63/5.00 ± 0.92), felt that physical exams conducted via telemedicine were “Slightly Effective” (1.88/5.00 ± 0.99), and believed that 43.5% of visits required an in-person component. Most adult reconstructive surgeons would continue to use telemedicine in the future (87.5%). Conclusion. Telehealth emerged as a valuable tool during the COVID-19 pandemic. Arthroplasty patients and surgeons were generally satisfied with telehealth and see a role for telehealth after the pandemic. Future investigations should explore how to improve telehealth physical examinations and identify which types of visits and patient concerns are reliably addressed using telehealth

Introduction. Surface sensor technology provides useful information about the status of an individual's health and been available for many years, but has not been widely adopted by orthopaedic surgeons. However, its usage may be become more prominent as COVID-19 has created a shift towards telemedicine. This study reports the use of a joint specific surface sensor to remotely monitor the recovery of patients who underwent knee replacement surgery prior to the enforced stay-at-home social distancing necessitated by the COVID-19 pandemic. Methods. The study group consisted of 29 patients who underwent primary, unilateral total knee arthroplasty (TKA). A knee joint specific surface sensor (TracPatch™) was placed following surgery and kept on patients for 3 weeks postoperatively. The patients’ range of motion (ROM), exercise compliance, distance walked, pain, skin temperature, and incision appearance were monitored and transmitted electronically to health care providers. Patients were grouped by gender, age and BMI for analysis of functional outcome measurements. Results. Patients tolerated wearing the device without complications. Additionally, both patients and physicians were able to monitor patient data in real time via a mobile phone or web application. The mean maximum flexion and minimum extension did not significantly change from postoperative week 1 to postoperative week 2 and week 3. However, the mean number of steps taken increased from 4,923 steps in postoperative week 1 to 8,163 steps week 2 (p=0.01) and 11,615 steps week 3 (p<0.001) postoperatively. There were no statistically significant differences in ROM or number of steps between the different gender, age, and BMI groups. Conclusion. The use of a joint specific surface sensor that provides novel pre- and postsurgical information is a valuable addition to surgeons’ remote care capability. These devices promise to accelerate the adoption of telehealth by orthopedic surgeons

BACKGROUND. Telerehabilitation has been shown to both promote effective recovery after shoulder arthroplasty and may improve adherence to treatment. Such systems require demonstration of feasibility, ease of use, efficacy, patient and clinician satisfaction, and overall cost of care, and much of this data has yet to be provided. Few augmented reality rehabilitation approaches have been developed to date. Evidence suggests augmented reality rehabilitation may be equivalent to conventional methods for adherence, improvement of function, and relief of pain seen in these musculoskeletal conditions. We proposed that the development of an augmented reality rehabilitation platform during the pre and postoperative period (including post-shoulder arthroplasty) could be used to track patient activity and range of motion as well as promote recovery. METHODS. A prototype augmented reality platform equipped with a motion sensor system optimised for the upper arm was developed to be used to validate 4 arcs of shoulder motion and complete directed upper arm exercises designed for post-shoulder arthroplasty rehabilitation was built and tested. This system combined augmented reality instructions and motion tracking to follow patients over the course of their therapy, along with a telehealth patient-clinician interface. FINDINGS. The augmented reality platform was tested to validate shoulder range of motion examination similar to that of standard goniometer measurements. Healthy test subjects without shoulder pain or prior shoulder surgery performed the arcs of motion for 5 repetitions as part of a home therapy program. Each motion was measured with angular measurements as a proof of concept with high degree precision (less than 5 degrees). Remote patient-clinician interface testing was also conducted along with a clinician established therapy plan. DISCUSSION. Augmented reality systems that track patients' complex movements, including clinical shoulder range of motion, suggest the promising future of telerehabilitation in arthroplasty, particularly in telemonitoring before and after surgery. As this technology continues to gain acceptance, further studies that evaluate the outcomes of augmented reality rehabilitation for long-term follow-up are needed

Introduction. Employer-sponsored travel surgery programs for commonly performed procedures like total joint arthroplasty (TJA) are increasing, as employers try to more effectively manage the healthcare costs of their employees. This new approach by employers to direct their employees to designated “Centers of Excellence” (COEs) creates a need to characterize the “travel patient” population that commutes long distances to receive their surgical care and returns home for their rehab shortly after surgery. Electronic patient rehabilitation platforms (EPRA) facilitate communication, patient navigation, and care coordination across this complex episode of care and may contribute to improved outcomes after TJA. The aim of this study is to evaluate patient satisfaction, functional outcomes and engagement with the use of an EPRA among two TJA cohorts: 1) travel and 2) non-travel TJA patients. Methods. A retrospective review was performed on total knee (TKA) and total hip (THA) arthroplasty patients at a single institution during the first 6 months following implementation of an EPRA. All patients were offered internet based access to an EPRA which provided instant messaging with the care team, algorithmic navigation of the patient during the pre and post-op phases, and access to an extensive library of educational videos regarding their surgery, rehab, and FAQs. Primary outcome measures were the pre-op and 12 week post op HOOS Jr. and KOOS Jr. Patient satisfaction at 12 weeks after surgery and engagement metrics for the EPRA were also examined. Cases were separated into two groups: travel and non-travel, and the groups were compared in terms of engagement, improvement in functional outcomes, and patient satisfaction. Chi-square test and t-test statistics were used for analysis. Results. 634 TJA cases (100 travel; 534 non-travel) were included in this study. Age and BMI differed significantly between these cohorts (p<0.001). The mean age and BMI were 59.17 and 33.01, respectively for travel patients and 69.27 and 29.56, respectively for non-travel patients. 97% of the travel patients initially opted-in to use the electronic rehabilitation program compared to 87.6% of the non-travel patients. The number of travel patients logging in, watching videos, and messaging was significantly higher than that of non-travel patients (p<0.01). On average, travel patients generated double the number of sessions than non-travel patients (71.5 vs 31.5, p<0.001). Among TKA cases, travel patients reported significantly lower pre-op mean KOOS Jr. scores than non-travel patients (43.11 vs. 47.78, p< 0.01). By 12 weeks, there was no difference between the groups (67.11 vs. 70.05, p=0.15). THA cases exhibited similar increases in patient reported outcomes(PROs). Mean pre-op HOOS Jr scores for travel and non-travel patients were 42.64 and 48.16 respectively (p=0.07) and mean post-op HOOS Jr. scores at 12 weeks were 75.93 and 80.12, respectively (p=0.15). Comparing 12 week procedure satisfaction (0–5), travel THA patients reported significantly higher mean satisfaction than non-travel THA cases (4.93 vs 4.32, p<0.001). There was no difference in satisfaction between travel TKA and non-travel TKA cases (4.31 vs 4.35, p=0.85). Conclusion. This study revealed higher engagement among travel patients in comparison to non-travel patients as measured by utilization of EPRA. Patients participating in these programs are typically incentivized financially in terms of enhanced insurance coverage and elimination of out-of-pocket expenses when they obtain care at an employer designated COE which may contribute to this increased degree of engagement. Increased utilization of EPRA may have also contributed to higher 12 week patient satisfaction. Despite the logistical challenges of travel TJA surgery, the EPRA used in this study appears to facilitate effective patient navigation and care coordination in the travel patient population, resulting in patient reported outcomes and satisfaction that is comparable to our non-travel patient population. Considering the projected increased growth of these employer directed COE programs, further understanding of these travel surgery patients and the role of electronic patient engagement platforms and telehealth technologies is warranted.
