After agreeing to participate and signing the informed consent, subjects will be randomized into in person physical therapy group or telerehabilitation group. At the 2-week postoperative visit, the subject will receive a sealed envelope which will contain the information about the group they have randomly been assigned to. Both groups (in person therapy and telerehabilitation) are expected to start physical therapy at 6-week after surgery, this means that all subjects will have 4 weeks after being assigned to program and organize for physical therapy.

Subjects who are randomized to in-person therapy will present to a physical therapist of their choice with a established written protocol. The therapy protocol is developed in conjunction with the Department of Orthopaedic Surgery and the Department of Physical Therapy. Subjects are recommended to attend in-person appointments at least once a week as well as perform home exercises. Progress with therapy will be collected with weekly phone calls from the research team. It is expected most subjects will complete formal physical therapy by 6 months postoperative attending on average 5-6 visits, measured by the time at which patient's regain functional range of motion or are instructed by their therapist to discontinue. Shoulder range of motion will be measured with a goniometer preoperatively, as well as 3,6, 12, and 24 months postoperatively at their regularly scheduled clinic visit. (Shoulder arthroplasty patients regularly return to clinic at these intervals and would not be required to present to clinic in addition to these time points. Patients also regularly return to clinic at 2 weeks and 6 weeks postoperatively as a part of their normal clinical follow up for wound check and general assessment.) Subjects who are randomized to telerehabilitation will be provided access to telemedicine visits with a physical therapist. These patients will have one first in-person physical therapy visit before starting telerehabilitation, and another in-person physical therapy visit at 3 months to assess progress. Telerehabilitation visits will be performed via secure usage of the electronic medical record (EMR). Progress with telerehabilitation will be collected with weekly phone calls from the research team. To ensure uniformity, and to allow for appropriate access to telehealth services, all telehealth visits will be carried out through the study institution's Department of Physical Therapy. It is expected most patients will complete formal physical therapy by 6 months postoperative measured by the time at which patient's regain functional range of motion or patients are satisfied with their results. Shoulder range of motion will be measured with a goniometer preoperatively, as well as 3,6, 12, and 24 months postoperatively at their regularly scheduled clinic visit. (Shoulder arthroplasty patients regularly return to clinic at these intervals and would not be required to present to clinic in addition to these time points. Patients also regularly return to clinic at 2 weeks and 6 weeks postoperatively as a part of their normal clinical follow up for wound check and general assessment.)

Review of the medical record will collect the following demographic information: medical record number, surgical date, age, BMI, smoking status, rheumatoid arthritis diagnosis, rotator cuff arthropathy diagnosis, subscapularis repair description, intraoperative integrity of the rotator cuff, physical therapy modality (in-person vs. telerehabilitation), physical therapy progress notes, and therapy compliance. Outcome measures will include shoulder range of motion including forward flexion, internal and external rotation, and all patient-reported outcome measures (PROs) assigned to shoulder arthroplasty patients already available for collection in Epic.
