TOTAL KNEE REPLACEMENT PROCEDURE

Four Basic Steps To A Total Knee Replacement

The procedure itself takes one to two hours, and the basic steps are as follows:

1. Your surgeon first removes damaged cartilage and bone surface from the ends of your tibia and femur.

2. Metal implants (knee prosthesis) are used to replace the surface areas of the joint. The artificial knee may be sealed to your bone using surgical cement, or a cement-less approach may be used involving press-fit components, which have a porous or textured surface into which bone can grow and attach to the prosthesis over time.

3. Surgeons who use VERASENSE in total knee replacement then insert this sensor technology between the metal components. As the knee is taken through the range of motion, the sensor device sends data wirelessly to a monitor in the operating room, which the surgeon uses to guide soft tissue adjustments and implant position, helping to improve knee balance. Knee balance and stability are important factors that contribute to a successful knee replacement.

4. Finally, after the knee is balanced and positioned, VERASENSE is removed and replaced with a medical-grade plastic spacer to create a smooth gliding surface.
