Implication

Case-control study reveals glenoid bone loss over 13.5 percent predicts recurrent shoulder instability in collegiate football players, indicating arthroscopy is reliable only below this threshold.

Key Points

To assess the effect of subcritical glenoid bone loss and athletic exposure on recurrent shoulder instability after primary arthroscopic stabilization in intercollegiate American football players.
Case-control study evaluating 50 intercollegiate football players undergoing primary arthroscopic stabilization for anterior shoulder instability who returned to play for at least one season.
Excluded shoulders with glenoid bone loss >20%, engaging Hill-Sachs lesions, off-track lesions, or concomitant rotator cuff repairs; followed patients through athletic exposures and subsequent military service (mean 3.2 years).
Recurrent instability occurred in 3 of 50 players (6%; 95% CI, 1.3%-16.5%) over a mean follow-up of 1.5 football seasons.
Recurrent instability occurred in 3 of 3 shoulders (100%; 5.31 cases per 1000 athlete-exposures) with >13.5% glenoid bone loss compared to 0 of 47 shoulders (0% across 72,000 athlete-exposures) with <13.5% bone loss (X2 = 15.80, P < .001).
Shoulders with multiple preoperative instability events required significantly more suture anchors (P = .005) and showed broader glenoid rim lesions (P = .001) than those stabilized after a single event.
