In reverse total shoulder arthroplasty (rTSA) phase 2 rehab, active shoulder ROM is initiated in which week?

• A. Week 2
• B. Week 3
• C. Week 4
• D. Week 6

Answer: (C)

After a reverse total shoulder arthroplasty, rehab moves from protecting the joint to gradually loading and restoring motion as tissues heal. The reverse design shifts the lifting task to the deltoid, so early movements focus on protection of the prosthesis and surrounding soft tissues rather than strengthening the rotator cuff. Active range of motion is introduced only once healing has progressed enough to tolerate active muscle contraction without risking dislocation or component stress. This typically occurs around the end of the first month after surgery, when the soft tissues and the joint have gained enough stability to handle active activity. Starting active ROM too early increases the risk of dislocation or loosening, while waiting too long slows progress, so the initiation around the end of the first month represents a balance between protection and progression.
