A stifle stabilization system is provided herein. The system comprising a femoral component having a leg portion and bottom portion, the bottom portion including an interconnected coupling member protruding therefrom, an articular sliding insert component defining a channel corresponding in size and shape to at least part of the coupling member, and a tibial component having a first proximal planar portion defining a slot, the slot being of corresponding and complementary shape to the articular sliding insert component to receive the articular sliding insert component therein, wherein, when the channel receives the at least part of the coupling member and the articular sliding insert component is received in the slot of the tibial component, the tibial component is interlocked with the femoral component with translational and rotational movement therebetween.
