Dillon MT, Chan PH, Prentice HA, et al. - The study was attempted to assess risk of revision after anatomic total shoulder arthroplasty (TSA) according to the glenoid component design. Between 2010 and 2017, researchers performed a cohort study including patients aged ≥18 years who had undergone primary elective TSA for the diagnosis of osteoarthritis. They excluded individuals with missing implant information, who received stemless humeral implants, or who received augmented glenoid implants. Applying multivariable competing risk regression, the risk of glenoid loosening as a cause-specific revision by the glenoid component design was assessed. The final cohort included a total of 5,566 TSA. They found glenoid component designs to be correlated with differential risks in revision due to glenoid loosening with polyethylene all-cemented pegged glenoids and when compared with polyethylene central-pegged ingrowth glenoids, polyethylene cemented keeled glenoids having higher risks. When conducting anatomic TSA, surgeons may want to recognize the glenoid component design.
