Systematic review and meta-analysis comparing pegged vs. keeled glenoid components in anatomic TSA across 7 comparative and 25 noncomparative studies, asking whether fixation type affects revision rates, functional outcomes (ASES, Constant), and radiolucency rates.
When counseling patients or selecting implants for anatomic TSA, recognize that pegged glenoid components carry a statistically lower revision risk than keeled designs — but expect equivalent patient-reported functional scores regardless of which you use, and do not rely on postoperative radiolucent lines alone as a marker of impending failure or need for revision.
