Abstract
Background: Current knee braces are not being used for extended periods by knee OA patients due interface problems; so compliance is an issue. The aim of this study was to design a new orthosis which could be providing the required correction to reduce medial compartment loading. Case Description and Methods: A new knee orthosis was initially evaluated on walking in two volunteer subjects with grade 2 medial compartment knee OA. Findings and Outcomes: The knee adduction angle was significantly reduced, and the speed of walking significantly increased when wearing the orthosis. An increase the knee range of motion, in step length was also observed with the orthosis. Conclusion: The orthosis provided frontal plane correction of the knee during walking. It could therefore prove to be suitable for use by knee OA patients.
