Cabarcas BC, et al. - Authors established the time point of maximum medical improvement (MMI) following reverse total shoulder arthroplasty (rTSA). MMI was achieved by the patients at 1 postoperative year following rTSA. Within the first 3 months, subjective symptoms were seen to improve rapidly and this improvement continued to gradually improve until 1 year. Patients should be counselled by the surgeons with these evidence-based expectations for clinical recovery, particularly the time frame of expected improvements in pain, function, and range of motion, as well as risks of and plans of action for postoperative complications.
