Evaluation of thirty eight cemented pegged glenoid components with variable backside curvature: two-year minimum follow-up

摘要

Background The PERFORM (TM) pegged glenoid system has been used for shoulder arthroplasty since 2012. This system offers multiple backside curvatures per size to better match variable patient anatomy. As a result, less reaming is required and subchondral bone is preserved-a critical factor in preventing glenoid migration and loosening, thus enhancing implant longevity.
