In anatomic TSAs, the main options for glenoid fixation currently involve keeled or pegged components. The aim of this review was to determine which fixation option provides optimal long-term functional outcomes with decreased rates of revision surgery and radiolucency. All studies were screened in duplicate for eligibility. Two separate analyses were completed examining noncomparative and comparative studies independently. A total of 7 comparative studies and 25 noncomparative studies were included in the final analysis.
Meta-analysis of the comparative studies demonstrated a higher rate of revision surgery with keeled fixations compared with pegged fixations odds ratio, 6. No significant difference was found with respect to functional outcomes, such as the American Shoulder and Elbow Surgeons score mean difference, 9. Pegged glenoid fixation may result in a decreased risk of revision TSAs, but no significant differences in patient-reported outcomes have been identified to date.

The use of anatomic total shoulder arthroplasty TSA for the treatment of primary osteoarthritis, rheumatoid arthritis, and other glenohumeral pathologies reduces pain, improves movement, and increases power. Surgical techniques and total shoulder components have evolved in an effort to continue to improve long-term outcomes. A quickly evolving area is glenoid component design and fixation.
