Zusammenfassung:	Methods, systems, and apparatuses are disclosed for a tibial component having shock absorbing features. In one embodiment, a tibial component of a knee joint prosthesis is provided, the tibial component comprising: a body portion; an upper surface; a first concave fossae comprising a first condyle contact surface; a second concave fossae comprising a second condyle contact surface; a lower surface; a side portion extending between the upper surface and the lower surface; a first bearing portion; a second bearing portion; and at least one cavity extending into the body portion from the lower surface; wherein a load applied substantially normally to the first condyle contact surface and the second condyle contact surface causes a tensile stress within the first bearing portion and the second bearing portion, and a compressive stress within the side portion.
