Physical Therapy After Reverse Total Shoulder Arthroplasty

A common operation for various shoulder conditions is a total shoulder arthroplasty (TSA). In cases with severe rotator cuff tears or other conditions, a variant of the procedure called a reverse total shoulder arthroplasty may be performed. It is unclear whether or not patients require formal physical therapy (as opposed to no physical therapy with recommended avoided movements) after reverse TSA. Orthopaedic surgeons have varying opinions on the postoperative rehabilitation protocol for reverse TSA, with some surgeons not prescribing any physical therapy. The purpose of this study is to randomize patients into two groups: one that sees a physical therapist after their reverse TSA, and one that is provided with actions not to perform and are allowed to self-rehabilitate.

The purpose of this study is to randomize patients into two groups: one that sees a physical therapist after their reverse TSA, and one that is provided with actions not to perform and are allowed to self-rehabilitate. There is very limited orthopaedic literature focusing on the postoperative rehabilitation after reverse TSA. The majority of research is in the physical therapy literature focusing on the actual rehabilitation protocol. However, there has never been a large, randomized clinical trial that asks the question of whether or not physical therapy after reverse TSA is even necessary, or if patients will have comparable outcomes if they perform their own at home rehabilitation. There are surgeons nationwide that are on either end of the spectrum. Some encourage patients to see a therapist for a prolonged period of time with a set regimen of exercises, while others do not encourage any formal physical therapy and instead give patients a list of movements not to perform and allow them to recover at their own pace. We hypothesize that there will be comparable clinical outcomes between patients randomized to receive physical therapy versus an at home, self-led rehabilitation protocol. There are no deleterious effects of either treatment wing. Patients who agree to undergo reverse TSA after a preoperative appointment with their attending surgeon will be invited to participate in the study. They will complete the below mentioned survey instruments. They will receive their procedure and appropriate postoperative treatment. Patients will then be randomized to either the physical therapy or self-rehab group. Both groups will receive the standard postoperative physical therapy protocol. The only difference between the groups will be if a physical therapist sees the patients in their clinic, or if the patients self-rehabilitate with a list of limitations throughout their recovery course. The physical therapy protocol provided to the physical therapists and patients is attached. Clinical outcomes will be measured using the attached survey instruments: Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons Shoulder Score (ASES-SS), and the Single Assessment Numeric Evaluation score (SANE). These are commonly used, validated survey instruments in the setting of orthopaedic shoulder research. The physical exam component of the study will include range of motion testing (measuring the degrees of movement using a goniometer) and strength testing (measured using the dynamometer) in both shoulders. These survey instruments and measurements will be performed at 3, 6, and 12 month postoperative follow up.

There will be two groups of patients randomized either to receive formal physical therapy in clinic or a self-led at home rehabilitation regimen.

The physician will not know if the patient is receiving at home physical therapy or seeing a physical therapist in clinic.

This group of patients will receive a predetermined physical therapy regimen with guidance from a physical therapist.

This group of patients will be provided with a list of actions not to perform during the stages of their rehab (to avoid injury), and allowed to rehab their shoulder at their own pace.

These patients will receive a formal physical therapy protocol by seeing a physical therapist in clinic.

These patients will be provided with a list of actions NOT to perform and allowed to self rehabilitate. They will not see a physical therapist.
