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 prior to arthroplasty include:
· Anti-inflammatory medications
· Pain medications
· Limiting painful activities
· Assistive devices for walking (such as a cane)
· Physical therapy
· Cortisone injections into a knee joint
· Visco-supplementation injections (to add lubrication into the joint to make joint movement less painful)
· Weight loss (for obese people)
· Glucosamine and chondroitin sulfate
· Exercise and conditioning
People who have arthroplasty generally have substantial improvement in their joint pain, ability to perform activities, and quality of life, so these are important reasons for the procedure as well.
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 health care provider to recommend arthroplasty.
What are the risks of Arthroplasty?
As with any surgical procedure, complications can occur. Some possible complications may include:
· Blood clots in the legs or lungs
· Loosening of prosthetic parts
· Nerves or blood vessels in the area of surgery may be injured, resulting in weakness or numbness.
· The joint pain may not be relieved by the surgery.
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your health care provider prior to the procedure.
How do I prepare for Arthroplasty?
· Your health care 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 health care 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 health care provider if you are sensitive to or are allergic to any medications, latex, tape, and anesthetic agents (local and general).
· Tell your health care provider of all medications (prescribed and over-the-counter) and herbal supplements that you are taking.
· Tell your health care provider if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that affect blood clotting. It may be necessary for you to stop these medications prior to the procedure.
· If you are pregnant or suspect that you are pregnant, you should notify your health care provider.
· You will be asked to fast for 8 hours before the procedure, generally after midnight.
· You may receive a sedative prior to the procedure to help you relax.
· You may meet with a physical therapist prior to your surgery to discuss rehabilitation.
· Arrange for someone to help around the house for a week or two after you are discharged from the hospital.
· Based on your medical condition, your health care provider may request other specific preparation.
What happens during Arthroplasty?
Arthroplasty requires a stay in a hospital. Procedures may vary depending on your condition and your doctor'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 doctor will make an incision in the area of the joint.
· The doctor 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 requires 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 medication so that you can participate in the exercise. 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 health care 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 health care 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 soreness as recommended by your health care provider. Aspirin or certain other pain medications may increase the chance of bleeding. Be sure to take only recommended medications.
Notify your health care provider to report any of the following:
· Redness, swelling, bleeding, or other drainage from the incision site
· Increased pain around the incision site
· Numbness and/or tingling of the affected extremity
