  Knee orthotic devices are widely proposed by physicians and medical
practitioners for preventive or therapeutic objectives in relation with their
effects, usually known as to stabilize joint or restrict ranges of motion. This
study focuses on the understanding of force transfer mechanisms from the brace
to the joint thanks to a Finite Element Model. A Design Of Experiments approach
was used to characterize the stiffness and comfort of various braces in order
to identify their mechanically influent characteristics. Results show
conflicting behavior: influent parameters such as the brace size or textile
stiffness improve performance in detriment of comfort. Thanks to this
computational tool, novel brace designs can be tested and evaluated for an
optimal mechanical efficiency of the devices and a better compliance of the
patient to the treatment.
