The relationship between age and gait characteristics in people with and without
medial compartment osteoarthritis (OA) remains unclear. We aimed to characterize
this relationship and to relate biomechanical and structural parameters in a
subset of OA patients. Twenty five participants with diagnosed unilateral medial
knee OA and 84 healthy participants, with no known knee pathology were recruited.
3D motion capture was used to analyse sagittal and coronal plane gait parameters
while participants walked at a comfortable speed. Participants were categorized
according to age (18-30, 31-59 and 60+ years), and those with and without OA were
compared between and within age groups. In a subset of OA patients, clinically
available Computed Tomography images were used to assess joint structure.
Differences in coronal plane kinematics at the hip and knee were noted in
participants with OA particularly those who were older compared with our healthy
controls, as well as increased knee moments. Knee adduction moment correlated
with structural parameters in the subset of OA patients. Increased knee moments
and altered kinematics were observed in older participants presenting with OA
only, which seem to be related to morphological changes in the joint due to OA,
as opposed to being related to the initial cause of medial knee OA.
