- •
Knee kinematics & muscle strength were examined in patients with osteoarthritis.
- •
Joint contact during downhill gait was assessed using Dynamic Stereo X-ray methods.
- •
160">Patients with osteoarthritis had increased knee contact point excursion & velocity.
- •
Altered knee contact patterns were associated with increased varus knee motion.
- •
However, muscle weakness was not associated with altered knee joint contact.
