Radiographic findings of patients with XLH who presented with varus and valgus deformity at the hip, knee, and ankle.

Deformity analysis	Varus	Normal	Valgus
n = 86 legs
Hip (LPFA: 85–90)	88.4% (76)	8.1% (7)	3.5% (3)
Knee/femur (LDFA: 85–90)	52.3% (45)	40.7% (35)	7.0% (6)
Knee/tibia (MPTA: 85–90)	32.5% (28)	51.2% (44)	16.3% (14)
Ankle (LDTA: 86–92)	33.7% (29)	51.2% (44)	15.1% (13)

Percentages are listed inside the brackets. The standard angle measurements according to Paley et al. (14, 15) were used to analyze the full-length anteroposterior radiographs of both legs in standing position using the TraumaCad software (Brainlab AG, Munich, Germany).
