Arthroplasty is a surgery to restore the function of a joint. A joint can be restored by replacing the joint with plastic and metal parts. An artificial joint (prosthesis) will be used.

Various types of arthritis may affect the joints. Osteoarthritis is the most common reason for arthroplasty. This is a common degenerative joint disease. It causes a loss of the cartilage or cushion in a joint.

Arthroplasty may be used when medical treatments no longer relieve joint pain and disability. Some treatments for osteoarthritis that may be used before arthroplasty include:

• Anti-inflammatory medicines
• Pain medicines
• Limiting painful activities
• Assistive devices for walking, such as a cane
• Physical therapy
• Cortisone injections into the joint
• Viscosupplementation injections to add lubrication into the joint. This is to make joint movement less painful.
• Loss of excess weight
• Exercise and conditioning
• Bracing

People who have arthroplasty usually have a lot of relief from their joint pain. They are more able to do daily activities, and have a better quality of life.

Most joint arthroplasty is done on the hip, knee and shoulder. Arthroplasty on the ankle, elbow, and fingers is done less often.

There may be other reasons for your doctor to advise arthroplasty.

All surgery has risks. The risks of this surgery include:

• Bleeding
• Infection
• Blood clots in the legs or lungs
• Loosening of prosthetic parts
• Stiffness or pain that does not go away

Nerves or blood vessels in the area of surgery may be injured. This results in weakness or numbness. The joint pain may not be relieved by the surgery. Or full function of the joint may not return.

There may be other risks depending on your overall health. Talk about any concerns with your doctor before the procedure.

• Your doctor will explain the procedure to you. Ask any questions that you have about the procedure.
• You will be asked to sign a consent form. This gives your permission to do the procedure. Read the form carefully. Ask questions if something is not clear.
• Your doctor will ask about your health history. They may also give you a physical exam. This is done to make sure you are in good health before having the procedure. You may have blood tests or other diagnostic tests.
• Tell your doctor if you are sensitive to or are allergic to any medicines, latex, tape, metals, and anesthesia medicine (local and general).
• Tell your doctor of all medicines (prescribed and over-the-counter) and herbal supplements that you are taking.
• Tell your doctor if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medicines. Tell them if you take aspirin, or other medicines that affect blood clotting. You may need to stop these medicines before the procedure.
• If you are pregnant or may be pregnant, tell your doctor.
• You will be asked to not eat for about 8 hours before the procedure, generally after midnight.
• You may receive a sedative before the procedure to help you relax.
• You may meet with a physical therapist before your surgery to talk about rehabilitation.
• Arrange for someone to help around the house for 1 or 2 weeks after you go home from the hospital.
• Based on your overall health, your doctor may advise other kinds of preparation.

Arthroplasty may be done as a same day surgery. Or it may need a stay in a hospital. Ask your doctor about the length of your stay. Procedures may vary depending on your condition and your doctor's practices.

Arthroplasty may be done while you are asleep under general anesthesia. Or it may be done while you are awake under local anesthesia. Your anesthesiologist will talk with you in advance.

Generally, arthroplasty follows this process:

1. You will be asked to remove clothing and will be given a medical gown to wear.
2. An I.V. line may be started in a vein in your arm or hand.
3. You will be positioned on the operating table in a way that gives the best access to the joint to be treated.
4. A urinary catheter may be inserted.
5. If there is a lot of hair at the surgical site, it may be shaved off.
6. The anesthesiologist will watch your heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
7. The skin over the surgical site will be cleaned with an antiseptic solution.
8. The doctor will make an incision in the area of the joint.
9. They will repair or remove the damaged parts of the joint.
10. The incision will be closed with stitches or surgical staples.
11. A sterile bandage or dressing will be applied.

After the surgery, you will be taken to the recovery room for observation. Once your blood pressure, pulse, and breathing are stable and you are alert, you may be able to go home. Sometimes you may need to stay overnight at the hospital. If so, you will be taken to your hospital room.

It is important to begin moving the new joint after surgery. A physical therapist will meet with you soon after your surgery. They will plan an exercise rehabilitation program for you. Your pain may be controlled with medicine so that you can take part in the exercise program. You will be given an exercise plan to follow.

You will go home or to a rehab center. In either case, you will need ongoing physical therapy until you regain muscle strength and good range of motion.

Once you are home, it will be important to keep the surgical area clean and dry. Your doctor will give you bathing instructions. The stitches or surgical staples will be removed during a follow-up office visit.

Take a pain reliever for pain as advised by your doctor. Aspirin or some other pain medicines may increase the chance of bleeding. Be sure to take only approved medicines.

Tell your doctor if you have any of these:

• Fever or chills
• Redness, swelling, bleeding, or other fluid leaking from the incision site
• Pain around the incision site that gets worse
• Numbness or tingling of the affected area
• Pain, swelling and redness in either leg or calf

You may go back to your normal diet unless your doctor tells you not to.

Don't drive until your doctor tells you to. You may be given other activity limits.

Making some changes to your home may help you during your recovery. These changes may include:

• Handrails along all stairs
• Safety handrails in the shower or bath
• Shower bench or chair
• Raised toilet seat
• Stable chair with firm seat cushion and firm back with two arms. This allows your knees to be lower than your hips when you sit.
• Long-handled sponge and shower hose
• Dressing stick
• Sock aid
• Long-handled shoe horn
• Reaching stick to grab objects
• Firm pillows to raise the hips above the knees when sitting
• Removing loose carpets and electrical cords that may cause you to trip

Your doctor may give you other instructions after the procedure.
