Abstract
In one embodiment, a method for treating an infected implant area of a knee joint comprises surgically accessing the implant area, and inserting a tibial component into the tibia using an antibiotic-impregnated material. A femoral component is formed that is configured to interact with the tibial component by stable knee joint articulation and motion. The femoral component is formed of an antibiotic-impregnated material using a mold. The femoral component is attached to the femur using an antibiotic-impregnated material, and the tibial component is interfaced with the femoral component to form a stable temporary knee joint capable of reducing the spread of infection while permitting movement of the knee joint.

21. A mold for forming a femoral component using an antibiotic-impregnated material, the mold comprising:
- a smooth U-shaped back surface with a recess for receiving the antibiotic-impregnated material, wherein the recess contains two depressions that are spaced apart from each other by a connecting portion, whereby the resulting femoral component comprises a one-piece structure having two outer surfaces that are spaced apart from each other by a center section, and wherein the femoral component includes a front surface that is configured to interface with a tibial component and a back surface that is configured to interface with a femur.

24. A mold for forming a femoral component using an antibiotic-impregnated material, the mold comprising:
- a smooth U-shaped back surface with a recess for receiving the antibiotic-impregnated material, wherein the recess contains two depressions that are spaced apart from each other by a connecting portion, wherein the U-shaped back surface comprises two spaced-apart inner side walls and a bottom, wherein the recess is formed in the bottom, and wherein the connecting portion is vertically below the bottom of the U-shaped back surface such that the center section of the resulting femoral component is formed when the antibiotic-impregnated material is placed into the recess, whereby the resulting femoral component comprises a one-piece structure having two outer surfaces that are spaced apart from each other by a center section, and wherein the femoral component includes a front surface that is configured to interface with a tibial component and a back surface that is configured to interface with a femur.
