Abstract Objective To investigate the biomechanics changes at lower limb joints of patients with early stage me
dial compartment knee osteoarthritis OA wearing different types of lateral wedges during walking and to define
which type of lateral wedge is potentially more suitable in the treatment of the medial compartment knee OA Meth
od Thirty patients with early stage medial compartment knee OA were enrolled Both kinematics and temporal pa
rameters were examined by Vicon Dimensional gait analysis system and the kinetics changes were tested by
two Kislter force platforms at the same time under three conditions a custom made traditional lateral wedge of
with standard shoes a custom made arch supported lateral wedges of with standard shoes control condition
standard shoes only Results Both two types of lateral wedges showed significantly decreased knee joints loading
knee adduction moment and knee adduction angular impulse P The decreased loading on OA knees in
traditional wedges condition was associated with an increased ankle valgus degrees moment and medial group reac
tion force when compared to the control and arch supported conditions P and the arch supported lateral
wedges showed an increased foot progression angles P Conclusion The results showed that under dynam
ic condition both two wedges showed decreased loading in the medial compartment at knees and the arch supported
wedges were found to be more comfortable and did not cause high loading in the ankle
