Factors Associated with Anchor-Number Preference Among Orthopedic Surgeons Performing Bankart Repair in Saudi Arabia: A Cross-Sectional Survey.

Abstract

Objective: This study described anchor-number preferences among orthopedic surgeons performing arthroscopic Bankart repair in Saudi Arabia and explored unadjusted associations with surgeon- and practice-related characteristics. Methods: A cross-sectional electronic survey used purposive recruitment across five Saudi regions. Descriptive analyses included 71 respondents. Because 'Both' represented case-dependent use rather than a discrete anchor count, these three responses were reported descriptively and excluded from inferential comparisons; exact analyses compared 1-2 anchors (n = 18) with 3-4 anchors (n = 50). Fisher-Freeman-Halton exact tests, Cramér's V, and bootstrap 95% confidence intervals were reported. Results: Fifty surgeons (70.4%; 95% CI: 59.0-79.8%) reported usually using 3-4 anchors. In exploratory unadjusted analyses, anchor-number preference was associated with annual Bankart-repair volume (exact p = 0.021; Cramér's V = 0.371, 95% CI: 0.194-0.548) and hypothetical future preference when cost and other factors were not considered (exact p = 0.044; Cramér's V = 0.298, 95% CI: 0.068-0.529). Other assessed associations were nonsignificant. Tear size and extent was the most frequently reported consideration (95.8%). Conclusions: Most respondents preferred 3-4 anchors, and tear size/extent was the most frequently reported consideration. The observed associations were exploratory and unadjusted and did not establish independent determinants, cost effects on actual practice, superior stabilization, or guideline recommendations.
