In summary, the present results confirm that
proprioception declines with age, and that this decline is
not simply the consequence of subclinical OA in the
elderly. Patients with knee OA have worse knee joint
position sense than elderly controls. Knee proprioception
appears to be correlated with disease-specific functional
status, and may contribute to functional status
outcome. Longitudinal studies are needed to determine
the impact of impaired proprioception on the development,
radiographic progression, and functional decline
of knee OA.
