Anatomic TSA vs RTSA for Glenohumeral Arthritis

There are no published prospective studies that compared 2-year functional outcomes of RTSA and anatomic TSA for the treatment of primary glenohumeral osteoarthritis with intact rotator cuffs and no excessive glenoid retroversion. The primary goal of our prospective randomized study is to determine whether RTSA have at least as good results as anatomic TSA (non-inferiority), in patients with glenohumeral osteoarthritis, without rotator cuff tears nor significant glenoid retroversion.
