Abstract

Background: Mild to moderate hip osteoarthritis is often managed clinically in a non-surgical

manner. Effective non-surgical management of this population requires characterizing the

specific impairments within this group. To date, a complete description of all lower extremity

kinematics in mild-to-moderate hip osteoarthritis patients has not been presented. The aim of

the present study is to describe the lower extremity gait kinematics in mild-to-moderate hip

osteoarthritis patients and explore the relationship between kinematics and pain.

Methods: 22 subjects with mild-to-moderate radiographic hip osteoarthritis (Kellgren-Lawrence

grade 2-3) and 22 healthy age and BMI matched control subjects participated. Kinematic

treadmill walking data were collected across all lower extremity joints. A two-way repeated

measures analysis of variance estimated mean differences in gait kinematics between groups.

Correlations between gait kinematics and pain were assessed using a Spearman Correlation

Coefficient.

Findings: Hip osteoarthritis subjects hiked their unsupported hemi-pelvis 1.40 degrees (P <

0.001) more than controls and tilted their pelvis 4.65 degrees more anteriorly (P = 0.01).

Osteoarthritis subjects walked with 4.30 degrees more peak hip abduction (P < 0.001), 8.57

degrees less peak hip extension (P < 0.001), and 10.54 degrees more peak hip external rotation

(P < 0.001). Kinematics were related to pain in the ankle frontal plane only (r=-0.43, P< 0.05).

Interpretation: Individuals with mild-to-moderate hip osteoarthritis demonstrate altered gait

biomechanics not related to pain. These altered biomechanics may represent effective
