What is arthroplasty?
Arthroplasty is a surgical procedure to restore the function of a joint. A joint can
be restored by resurfacing the bones. An artificial joint (called a prosthesis) may
also be used.
Various types of arthritis may affect the joints. Osteoarthritis, or degenerative
joint disease, is a loss of the cartilage or cushion in a joint, and is the most common
reason for arthroplasty.
Why might I need arthroplasty?
Arthroplasty may be used when medical treatments no longer effectively relieve joint
pain and disability. Some medical treatments for osteoarthritis that may be used before
- Anti-inflammatory medicines
- Pain medicines
- Limiting painful activities
- Assistive devices for walking (such as a cane)
- Physical therapy
- Cortisone injections into a knee joint
- Viscosupplementation injections (to add lubrication into the joint to make joint movement
- Weight loss (for obese people)
- Exercise and conditioning
People who have arthroplasty generally have substantial improvement in their joint
pain, ability to perform activities, and quality of life.
Most joint surgery involves the hip and knee, with surgery on the ankle, elbow, shoulder,
and fingers being done less often.
There may be other reasons for your healthcare provider to recommend arthroplasty.

What are the risks of arthroplasty?
As with any surgical procedure, complications can happen. Some possible complications
- Blood clots in the legs or lungs
- Loosening of prosthetic parts
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 and/or complete function
may not return.
There may be other risks depending on your specific medical condition. Be sure to
discuss any concerns with your healthcare provider before the procedure.
How do I prepare for arthroplasty?
- Your healthcare provider will explain the procedure to you and offer you the chance
to ask any questions that you might have about the procedure.
- You will be asked to sign a consent form that gives your permission to do the procedure.
Read the form carefully and ask questions if something is not clear.
- In addition to a complete medical history, your healthcare provider may perform a
complete physical exam to ensure you are in good health before undergoing the procedure.
You may undergo blood tests or other diagnostic tests.
- Tell your healthcare provider if you are sensitive to or are allergic to any medicines,
latex, tape, and anesthetic agents (local and general).
- Tell your healthcare provider of all medicines (prescribed and over-the-counter) and
herbal supplements that you are taking.
- Tell your healthcare provider if you have a history of bleeding disorders or if you
are taking any anticoagulant (blood-thinning) medicines, aspirin, or other medicines
that affect blood clotting. It may be necessary for you to stop these medicines before

- You will be asked to fast for 8 hours before the procedure, generally after midnight.
- You may receive a sedative before the procedure to help you relax.

What happens during arthroplasty?
Arthroplasty usually requires a stay in a hospital. Procedures may vary depending
on your condition and your healthcare provider's practices.
Arthroplasty may be done while you are asleep under general anesthesia, or while you
are awake under localized anesthesia. Your anesthesiologist will discuss this with
you in advance.
Generally, arthroplasty follows this process:
- You will be asked to remove clothing and will be given a gown to wear.
- An intravenous (IV) line may be started in your arm or hand.
- You will be positioned on the operating table in a manner that provides the best access
to the joint being operated on.
- A urinary catheter may be inserted.
- If there is excessive hair at the surgical site, it may be shaved off.
- The anesthesiologist will continuously monitor your heart rate, blood pressure, breathing,
and blood oxygen level during the surgery.
- The skin over the surgical site will be cleansed with an antiseptic solution.
- The healthcare provider will make an incision in the area of the joint.
- The healthcare provider will repair or remove the damaged parts of the joint.
- The incision will be closed with stitches or surgical staples.
- A sterile bandage or dressing will be applied.
What happens after arthroplasty?
In the hospital
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 will be taken
to your hospital room. Arthroplasty usually needs an in-hospital stay of several days.
It is important to begin moving the new joint after surgery. A physical therapist
will meet with you soon after your surgery and plan an exercise rehabilitation program
for you. Your pain will be controlled with medicine so that you can participate in
the exercise program. You will be given an exercise plan to follow both in the hospital
and after discharge.
You will be discharged home or to a rehabilitation center. In either case, your healthcare
provider will arrange for continuation of 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 healthcare
provider will give you specific bathing instructions. The stitches or surgical staples
will be removed during a follow-up office visit.
Take a pain reliever for pain as recommended by your healthcare provider. Aspirin
or certain other pain medicines may increase the chance of bleeding. Be sure to take
only recommended medicines.
Notify your healthcare provider to report any of the following:
- Fever or chills
- Redness, swelling, bleeding, or other drainage from the incision site
- Increased pain around the incision site
- Numbness and/or tingling of the affected extremity
You may resume your normal diet unless your healthcare provider advises you differently.
You should not drive until your healthcare provider tells you to. Other activity restrictions
Making certain modifications to your home may help you during your recovery. These
modifications include the following:
- Proper 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 will allow your
knees to be positioned lower than your hips
- 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 healthcare provider may give you additional or alternate instructions after the
procedure, depending on your particular situation.
