• Planar osteoarthritis
3.4 Mechanism of Action
The brace reduces or increases the varus moment on the knee joint depend­
ing on the chosen brace.
Two mechanisms influence the extent of the varus moment on the knee joint.
Initially the rigid bridging of the ankle joint in the frontal plane reduces ever­
sion in the lower ankle joint. At the same time, forces that can be adjusted at
the lateral contact point of the brace are transferred in the area of the lower
leg.
In the treatment of medial osteoarthritis of the knee (brace bar lateral), this
effect shifts the vector of the ground reaction force laterally. Immediate con­
sequences are the reduction of varus moment and relief for the medial com­
partment. In the treatment of lateral osteoarthritis of the knee (brace bar
medial), the force transmission point is shifted in the medial direction. This
increases the varus moment, relieving the lateral compartment. Strain can be
relieved on either the lateral or medial compartment depending on the brace
selection.
