Anatomic correlates of reduced hip extension during walking in individuals with mild-moderate XXXX .

@entity717 @entity571 @entity158 @entity570
To identify radiographic and MR features of @entity570 ( @entity571 ) related to reduced hip extension during walking. Sixty six subjects, were stratified into those with (n   =   36, KL   =   2, 3) and without (n   =   30, KL   =   0, 1) radiographic @entity570 . Cartilage and labrum lesions were graded semi-quantitatively on hip MRI. Alpha angle and lateral center edge (LCE) angle were measured. Sagittal kinematics and kinetics were calculated during walking at speed of 1.35   m/s using 3-D motion capture. All subjects completed @entity717 and @entity571 Outcome Score (HOOS), timed up and go, and 6   min walk tests. Variables were compared between the two groups using one-way ANOVA (adjusting for age). Correlations of radiographic and MR parameters with peak hip extension were calculated. The @entity571 group was older, had greater @entity158 , and limitation of function. They also had lower peak hip extension and higher peak hip flexion; and worse acetabular and femoral cartilage lesions. Peak hip extension and flexion correlated with KL grade, cartilage lesions in the inferior and posterior femur. Reduced hip extension and greater hip flexion during walking are present in high functioning (HOOS   >   85%) individuals with mild-moderate @entity570 , and are associated with cartilage lesions.
