The goals of this research study are the following:
1. To compare the effects of tele-rehabilitation-supported physical therapy versus
traditional home and/or clinic-based physical therapy for total knee replacement (TKR)
on 90-day health service use costs.
2. To compare tele-rehabilitation-supported physical therapy and traditional physical
therapy on patient-centered outcomes
3. To explore whether individual patient characteristics are associated with differential
improvement from 6 to 12 weeks assessed by patient-reported outcomes.
