Background Smartphones offer the possibility of assessing recovery mobility after total hip or knee arthroplasty (THA TKA) passively and reliably, as well facilitating collection patient-reported outcome measures (PROMs) with greater frequency. Questions/Purposes We investigated feasibility using mobile technology to collect daily step data biweekly PROMs track joint arthroplasty. Methods Pre- post-operative steps were recorded in prospectively enrolled patients (128 THA 139 via an app, which uses phone's accelerometer. During 6-month follow-up, also completed (the pain numeric rating scale, Hip Disability Osteoarthritis Outcome Score Joint Replacement [HOOS JR] Knee Injury [KOOS JR]), HOOS KOOS JR quality life domain a mobile-enabled web link. Results At least 6 months follow-up was by 65% for 68% TKA patients. Reasons non-completion included time commitment, phone battery, app issues, health complications. Responses from 78% requested returned 96% returning at one PROM. Step available 92% days male 86% female The most robust occurred early, within first 2 months. groups higher pre-operative more likely recover their maximum earlier point. Correlations between counts scores modest. Conclusion Assessing large amounts post-TKA post-THA is feasible. Completion rates good, making very useful collecting frequent PROMs. Being unable ensure that always carried phones limited our analysis counts.
