Outcomes of Reverse Total Shoulder Arthroplasty in Patients 60 Years of Age or Younger: A Systematic Review

Abstract

Reverse total shoulder arthroplasty (RTSA) has been traditionally performed in elderly, low-demand patients. However, indications for RTSA are expanding, and patients who potentially benefit from this procedure are not restricted to those who are elderly. The purpose of this review was to summarize reported outcomes of RTSA in patients aged 60 years or younger. We performed a systematic review of the literature to search for outcomes of RTSA in patients aged 60 years or less. Inclusion criteria were studies reporting clinical and/or functional outcomes of RTSA in patients aged 60 years or less with follow-up of greater than 2 years. Cadaveric studies and studies including patients aged greater than 60 years were excluded. Outcomes of interest were range of motion, functional scores (Constant, American Shoulder and Elbow Surgeons, Simple Shoulder Test, and visual analog scale for pain), implant survival, and complications. Four studies with a total of 193 patients met inclusion criteria with mean durations of follow-up of 34 to 140.4 months. At the final follow-up, all studies showed significant improvements in flexion, abduction, and all reported functional scores. Mean postoperative flexion and abduction ranged from 85.7° to 134° and from 79° to 111°, respectively. Implant survival ranged from 87.5% to 94.3% at the latest follow-up. Complication rates ranged from 15% to 39.1%. Early clinical and functional outcomes of RTSA in patients aged 60 years or lessare favorable. Long-term functional results and implant survival rates of RTSA are comparable to previous data from older patients. Therapeutic IV.
