Abstract

See full text

A prosthetic knee-joint assembly includes: (a) a proximal segment; (b) a distal segment pivotally disposed with respect to the proximal segment to form a knee joint; (c) a first coupling integral with the proximal segment that includes a first adjustable member having a frustopyramidal boss extending proximally with respect to the proximal segment that is adapted to mount the proximal segment to above-knee prosthetic knee components, where the frustopyramidal boss is slidably adjustable and/or rotatably adjustable with respect to the proximal segment; and (d) a second coupling integral with the distal segment that includes a second adjustable member having a second frustopyramidal boss extending distally with respect to the distal segment that is adapted to mount the distal segment to below-knee prosthetic limb components, and where the second frustopyramidal boss is slidably adjustable and/or rotatably adjustable with respect to the distal segment.
