Claim 0:
1. A hinged articulating spacer system for revision knee arthroplasty comprising:
a femur rod configured to be inserted into a distal end of a femur;
a tibia rod configured to be inserted into a proximal end of a tibia, wherein the tibia rod is hingedly coupled to the femur rod to form a hinged rod assembly and enable the tibia rod to rotate relative to the femur rod about a rotational axis;
a pre-formed femoral spacer component including bone cement impregnated with an antibiotic, the pre-formed femoral spacer component defining an opening through which the hinged rod assembly extends; and
a pre-formed tibial spacer component including bone cement impregnated with an antibiotic, the pre-formed tibial spacer component defining an opening through which the hinged rod assembly extends,
wherein the pre-formed tibial spacer component is configured to articulate with the pre-formed femoral spacer component as the tibia rod rotates relative to the femur rod about the rotational axis.
