From: Hip pain and its correlation with cam morphology in young skiers—a minimum of 5 years follow-up
The mean α-angle in skiers with cam morphology, with and without hip pain. The mean α-angle in skiers with cam morphology (α-angle ≥ 55°) stratified by hip pain and no hip pain in the left hip at baseline (top left), right hip at baseline (top right), left hip at the 5-year follow-up (bottom left), and right hip at the 5-year follow-up (bottom right). *A significant correlation between hip pain and α-angle at P < 0.05, using Spearman’s rank-order correlation test
