Hip cartilage thickness according to lateral acetabular coverage

LCEA (deg) Cartilage thickness (mm) Within-subject effect
Lateral Middle Fovea
<20 4.33 (0.66) 3.99 (0.65) 3.85 (0.82)
20–25 3.68 (0.73) 3.36 (0.70) 3.36 (0.59)
25–40 3.20 (0.89) 2.99 (0.72) 2.96 (0.67) F(2,492) = 13.956, P < 0.001

Between-subject Effect F(3,246) = 29.332, P < 0.001

aAll variables are represented as mean (SD).

Within-subject’s test for interaction of location and group (Greenhouse-Geisser): F(6,492) = 1.652, P = 0.144, partial η2 = 0.020.

Within-subject’s test for location only (Greenhouse-Geisser): F(2,492) = 13.956, P < 0.001, partial η2 = 0.054.

Pairwise comparisons show: lateral versus middle sourcil, P < 0.001; lateral versus fovea, P < 0.001; middle versus fovea, P = 1.000.

Between-subject’s test for LCEA group: F(3,246) = 29.332, P < 0.001, partial η2 = 0.263. Pairwise comparisons show: frank dysplasia versus all other groups, P < 0.001; borderline dysplasia versus all other groups, P < 0.001; normal acet coverage versus acet overcoverage (P = 0.043).
