Abstract:
1. A prosthetic knee-joint assembly for a prosthetic limb comprising: a proximal segment having a surface adapted for mounting to an above-knee prosthetic limb socket; a distal segment pivotally disposed with respect to the proximal segment and pivotable with respect to the proximal segment in at least an anterior-posterior direction to provide a knee-joint pivot point; and a coupling at least partially integrated within the distal segment, including an adjustable member having a frustopyramidal boss extending distally with respect to the distal segment, the frustopyramidal boss being adapted to mount the distal segment to below-knee prosthetic limb components, and the frustopyramidal boss being slidably adjustable with respect to the distal segment so as to be slidable in at least one of the anterior-posterior and medial-lateral directions, and rotatably adjustable with respect to the distal segment; wherein the coupling includes an opening extending through a distal end of the distal segment and a bolt extending through the opening, the bolt including a threaded section; wherein the at least a portion of the threaded section releasably engages a corresponding threaded section within the frustopyramidal boss; wherein the bolt and the frustopyramidal boss are rotatable relative to the distal segment; wherein a position of the fastener within the opening is selectively adjustable in at least one of the anterior-posterior and medial-lateral directions; and wherein the coupling selectively inhibits both rotation of the frustopyramidal boss and translation of the frustopyramidal boss in at least one of the anterior-posterior and medial-lateral directions.
