How long does reverse shoulder replacement take to work for a rotator cuff tear?

The operation changes how the shoulder joint moves so the deltoid muscle can help raise the arm when the rotator cuff cannot do so effectively. At first, the shoulder needs protection while the wound and repaired soft tissues settle. Therapy commonly starts with guided movement, then progresses to active use and strengthening. Improvement is not always linear: stiffness, tiredness and temporary soreness may appear after exercises.

The final range of movement depends on preoperative stiffness, muscle condition, bone quality, the surgical plan and how healing progresses. The goal is useful, safer function for everyday activities rather than forcing the shoulder through painful positions.

Use the sling and movement limits exactly as instructed. Keep the incision clean and attend planned reviews and physiotherapy sessions. Do not lift, push yourself up from a chair with the operated arm, or reach behind your back until your surgical team permits it. As exercises advance, increase use gradually and report pain that remains worse rather than settling after rest.

Contact the surgical team for increasing redness, drainage, fever, worsening pain, new weakness or a sudden change in shoulder shape or function. Seek urgent care for chest pain, severe breathlessness, or a cold, pale or numb hand.

Ask when you may stop using the sling, which movements carry a dislocation risk, and when driving, work or lifting can resume. Ask how progress will be measured and what amount of soreness after therapy should prompt a call.
