Comparison of dGEMRIC indices of intact and degenerated cartilage by quadrant
| Intraoperative cartilage assessment | Acetabular dGEMRIC indices (ms) | p value | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Disease-positive | Disease-negative | Peripheral versus peripheral | Central versus central | Combined versus combined | |||||
| Quadrant | Peripheral | Central | Combined | Peripheral | Central | Combined | |||
| AS (12°–3°) Beck > 2 (12/18 hips) |
510 ± 237 | 481 ± 198 | 496 ± 217 | 515 ± 174 | 500 ± 148 | 508 ± 160 | 0.918 | 0.66 | 0.715 |
| PS (12°–9°) Beck > 0 (7/18 hips) |
473 ± 224 | 415 ± 185 | 444 ± 205 | 651 ± 220 | 534 ± 166 | 592 ± 203 | 0.002 | 0.008 | < 0.001 |
Values are mean ± SD; dGEMRIC = delayed gadolinium-enhanced MRI of cartilage; AS = anterosuperior; PS = posterosuperior.
