Abstract
The present invention relates to a prosthetic knee. In one embodiment of the present invention, the knee has a femoral body and meniscal body. The femoral body has a femoral alignment member, and the meniscal body has a femoral side. Extending from the femoral side are at least two guiding protrusions that extend along the longitudinal axis of the meniscal body and define at least two sides of an alignment groove. The alignment groove slippingly receives the femoral alignment member. The femoral alignment is able to move within the alignment groove and slip over the alignment groove when a force of sufficient magnitude is applied to the prosthetic and revert into the alignment groove. In another embodiment of the present invention, the groove and the alignment components are reversed on the respective femoral and meniscal bodies.
