The medial compartment
knee osteo arthritis (OA) is the most affected location for OA. The main knee
biomechanics changes which are associated with the medial compartment knee OA are
less knee flexion value (the normal mean maximum knee flexion has been shown to
be 64.6° during walking, 98.6° during ascending, and 90.3 °during descending),
high knee varus angle and an increased the external knee adduction moment(EKAM) during walking and stairs climbing due to shifting the knee joint centre
more laterally and the centre of the load medially.

These changes lead to pain
during daily activities and progression of the knee OA. The EKAM is considered
as the most important variable in the frontal plan and has two peaks: The first
peak is a sharp one after initial contact during early stance phase, while the
second one is in the late stance phase. The first peak is affected by the
amount of knee varus, joint space narrowing, OA severity, and progression
level, while the second one is more correlated to the amount of toe out and
pain levels. Read more>>>>>>
