Radiographic parameters of Group I and Group II hips
| Parameter | Group I (no PAO) (n = 52) | Group II (PAO) (n = 45) | p value |
|---|---|---|---|
| LCEA (°) | 25.7 (−6 to 42) | 13.0 (−32 to −39) | < 0.001 |
| ACEA (°) | 22.4 (−28.3 to 53.5) | 7.8 (−46 to 47.5) | < 0.001 |
| AI (°) | 11.8 (−2.6 to 29.2) | 23.4 (−3 to 50) | < 0.001 |
| CTD (cm) | −1.8 (−4.7 to −0.1) | −2.2 (−5.5 to 0.4) | 0.2 |
| AHI | 0.75 (0.2 to 1.0) | 0.62 (0.3 to 0.9) | 0.001 |
Values are expressed as median, with range in parentheses; PAO = periacetabular osteotomy; LCEA = lateral center-edge angle; ACEA = anterior center-edge angle; AI = acetabular inclination; CTD = center-trochanteric distance; AHI = acetabulum-head index.
