Introduction: Anatomical total shoulder arthroplasty is an effective treatment adopted for patients with glenohumeral osteoarthritis. Loosening of the glenoid component represents one of the main failure mechanisms; however, doubts remain regarding the selection of the best implant for avoiding complication. Objective: evaluate the effectiveness between exclusive polyethylene (PE) glenoid implants and metal back (MB) implants. Methods: systematic review of randomized clinical trials (RCTs), comparing PE (keeled and pegged) versus MB implants. Results: eight RCTs were included, with 323 patients and 338 shoulders, 151 men, 157 women, aged between 60 and 74 years with follow-up from six weeks to ten years. Shoulder function through the Constant-Murley score, range of motion and pain through the Visual Analogue Scale, were important outcomes to access the PE components that showed no difference; meanwhile, there was a reduction in radiolucency lines (RL) up to grade two around 50% and 12.4% for complications and surgery revisions in favor of the peg over the keel. Compared to MB, there was 25% more RL around PE, however function and complication rates were equivalent. Conclusion: the PE component in anatomical total shoulder arthroplasty, shows more RL compared to MB, especially around the keel design.
