CHAPTER 47

Total Knee Replacement

A total knee replacement is the removal of the distal end of the femur and the proximal end of the tibia. A prosthesis is used to reestablish the joint.

Possible equipment needed for the procedure includes a small/minor joint replacement set and Stryker battery-powered drills.

A brief description of the procedure follows:

1. A Doane retractor is used to protect the medial collateral ligament.

2. An alignment guide is placed lateral to the tibial tubercle.

3. A power saw is used to resect the proximal end of the tibia.

4. Spacer/alignment blocks are used to check for valgus alignment.

5. The AP cutting guide is used to determine where to cut the femur.

6. The saw is used to resect the distal end of the femur.

7. Tibial and femoral ends are checked for size.

8. The trial components are placed and secured.

9. The joint is evaluated and the trials are removed.

10. A prosthesis is chosen and placed. Both a femoral impactor and a tibial impactor are needed. A mallet is used to seat each component.

47-1 Micromill driver and attachments. (Many surgeons are using the Stryker System 5 in place of the Micromill driver.)
