We continue with another post knee arthroplasty and this time with a more targeted approach to the procedure and proper recovery. Remember that a knee replacement (also called knee arthroplasty) could more accurately be called a "resuperficialization" of the knee, because only the surface of the bones is actually replaced.

There are four basic steps to a knee replacement procedure.

• Bone Preparation. The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of the underlying bone.
• Positioning of metal implants. The removed cartilage and bone are replaced with metal components that recreate the surface of the joint. These metal parts can be cemented or "pressurized" into the bone.
• Resuperficialization of the kneecap. The surface below the kneecap is cut and resuperficialized with a plastic button. Some surgeons do not resuperficialize the kneecap, as the case may be.
• Insertion of a spacer. A medical plastic spacer is inserted between the metal components to create a smooth sliding surface.

It can take up to 3 months to fully recover from knee replacement surgery. Normally, patients can drive again between the fourth and sixth week, and return to work after 6-8 weeks. Physical therapy may be necessary for 3 months.

Patients must comply with instructions given by doctors, nurses, and physical therapist.

The patient may be asked:

• Taking iron supplements to help heal wounds and strengthen muscles
• Do not bend over or lift heavy things, at least for the first few weeks.
• Do not stand for long periods of time, as your ankles may swell.
• Use crutches, a cane, or a walker until your knee is strong enough to support your body weight.
• Take all medications according to instructions.
• Perform recommended exercises to encourage proper mobility
• Keeping the affected leg raised on a stool when sitting.
• Avoid wetting the wound until the scar is completely healed, due to the risk of infection.
• Monitor any signs or symptoms of infections, blood clots, or pulmonary embolism.
