Analyzing Knee Compartment Load for Arthritic Patient Under Variable Midsole Wedge Angle

In this study, knee compartment stresses were analyzed under variable midsole wedge angle. For each of wedge angle, two different coefficient of friction values were considered , one for the healthy and one for the arthritic patient.

Results shows that the stresses at the bone interface is directly influenced by the coefficient of friction while if we reduce the midsole wedge angle along the Center of pressure of the interacting bones, than it can reduce the stress at the knee interface. As in our case reducing the angle by 50% cause 24.3% reduction in medial compartment stresses, in turn providing significant releif to arthritic patient.
