Abstract
Improvements to a prosthetic knee-joint assembly include: a proximal segment having lower-profile design with a surface adapted for mounting to an above-knee prosthetic limb socket; a releasable lock featuring at least one of two complementary surfaces with radial grooves, which increase friction between the two surfaces to prevent rotation or sliding of a coupler component with respect to the knee-joint assembly; and visual indicia markings for determining the position of a distal coupling relative to the distal segment of the knee-joint.
