KNEE JOINT PROSTHESIS

摘要

A prosthesis in which the deepest point on the concave upper surface (15) of the shin member (5) is located substantially further forward than the geometrical centre of said upper surface; a guide pin (16) is substantially located at said deepest point and includes a body (17) with a circular cross-section and a head (18) which is wider than the body (17) and also has a circular cross-section; and a groove (11) in an intermediate plate (8) has a cross-section substantially matching the shape of the guide pin (16), so that it is pivotably and slidably engageable by said pin (16) with a reduced vertical clearance.
