Abstract
A prosthetic knee provides security and stability, particularly to low activity users, household and limited community ambulators, single and/or slow speed ambulators, and those with little voluntary control, while also balancing walking (dynamic) performance for low activity users. The prosthetic knee includes a housing, parallel anterior links, a posterior link, and a chassis. The geometry of the links and their relationship to one another allow for low voluntary control, shortening of mid-swing, which reduces stumbling risk, and geometric stability in stance. The anterior links are particularly oriented, sized and located to provide for stability. The anterior links both extend above the posterior link and substantially below the posterior link. The prosthetic knee includes a friction adjustment mechanism, a stability adjustment mechanism, and an adjustable extension assist mechanism.
