Artificial knee and prosthetic assembly kit therefor

An artificial knee comprising:

• first and second knee components connected together for rotation between an upright position and one or more rotated positions, wherein the first knee component has a first end configured for receiving a rod member and a second end that includes an extension member located in a generally central location of that end, and wherein the second knee component comprises a cylindrical member having a first end configured for receiving a rod member and a second end that includes a slot formed by a pair of side walls surrounding a U-shaped recess, with the slot being generally centrally located between the side walls and configured and dimensioned to allow the extension member of the first knee component to rotate therein, such that rotation of the knee components is achieved as the extension member rotates in the slot between the upright and rotated positions;
• a fastener for connecting together the first and second knee components, wherein the fastener passes through the side walls and slot of the second knee component and through the extension member of the first knee component to facilitate rotation of the knee components;
• and
• a biasing member comprising a flexible rod or tube of an elastomeric material operatively associated with the first and second knee components for urging those components towards the upright position, such that rotation of the second knee component toward a rotated position stretches or elongates the biasing member to provide a force that urges the knee components towards the upright position when one or both knee components are rotated.
