Unlike total knee replacement surgery, this less invasive procedure replaces only the damaged or arthritic parts of the knee.
Part of the damaged femur is removed so the surgeon can access the damaged part of the tibia.
Damaged meniscus is removed from the joint. Some bone is also removed to make room for the new tibial plastic component.
Cement is added to the newly prepared area, and the plastic tibial component is pressed into place.
From the damaged, arthritic area of the femoral condyle, a small amout of bone is removed and an opening is created for the metal femoral component.
The area is filled with bone cement, and the metal femoral component is pressed into place.
The new parts of the knee joint are tested by flexing and extending the knee through its range of motion.
