Reverse total shoulder arthroplasty (RTSA) represents one of the most important and consistent innovations of modern shoulder surgery. Since the 1990s there has been a progressive increase in RTSA implants. If they were initially used in eccentric glenohumeral arthropathy, nowadays are widely used in the treatment of concentric glenohumeral osteoarthrosis, of massive and irreparable tears of the rotator cuff, in trauma surgery and in revision surgery. RTSA is not without risks and complications. A greater interaction between orthopedist and physiotherapist is essential to allow easier and more structured treatment for the patient.
