It was reported from a journal article that was retrieved from the cureus journal of medical science that reported a retrospective cohort study from the united kingdom.The purpose of the study was to assess and compare postoperative functional and range of movement outcomes between a matched patient cohort aged over 70 who had undergone total shoulder arthroplasty (tsa) and reverse tsa.The study reviewed 75 patients with 44 receiving an anatomical tsa and 31 receiving a reverse tsa.All procedures were conducted using a deltopectoral approach with a zimmer biomet comprehensive shoulder replacement.The indication for surgery was glenohumeral degenerative changes and/or rotator cuff arthropathy.The study population had a mean age of 74.1 years at time of surgery (range 70-88 years) in the tsa cohort and 76.3 years (range, 70-90 years) in the rtsa cohort.Follow-up was conducted at three months, six months, and one year postoperatively with a minimum length of follow-up of one year.The study reported two patients in the tsa cohort experienced dislocations due to subscapularis failure within the one-year follow-up period; of which, for one patient, no further information regarding intervention or outcome was provided.
