What actually is done is only a few milli meter of the damaged cartilage and bone is removed from your thigh bone[FEMUR] and Leg bone[Tibia]and Knee cap[PATELLA] and replaced with metal prosthesis. The most important step in total knee replacement is your soft tissue balancing which has to be prciscise for better function of your knee. That’s why total knee replacement is considered more of a soft tissue procedure than bony procedure.
