What To Expect After Knee Replacement

How Long Do I Stay In Hospital After Total Knee or Hip Replacement in 2019?

A patients recovery and rehabilitation plan is crucial to the overall success of knee replacement surgery. A recovery and rehabilitation plan can help the patient:

  • Leave the hospital sooner
  • Regain knee strength and range of motion more quickly
  • Resume independent living sooner
  • Avoid potential complications

Typically, knee replacement patients are able to leave the hospital within 1 to 5 days , and they can take care of themselves and resume most activities 6 weeks after surgery. The majority of patients are 90% recovered after 3 months, though it can take 6 months or longer before they are 100% recovered.

Some knee replacement patients do not follow the typical recovery timeline. For example:

  • Patients who did knee-strengthening exercises in preparation for surgery sometimes recover more quickly.
  • Patients who are older, smoke, or have other medical conditions may take longer to heal.

Deviation from the typical recovery timeline cannot always be predicted, but these differences are usually okay as long as the patient, doctor, and physical therapist, continue to work together towards a full recovery.

What Happens During Knee Replacement Surgery

Once you are under general anesthesia or spinal/epidural anesthesia , an 8- to 12-inch cut is made in the front of the knee. The damaged part of the joint is removed from the surface of the bones, and the surfaces are then shaped to hold a metal or plastic artificial joint. The artificial joint is attached to the thigh bone, shin and knee cap either with cement or a special material. When fit together, the attached artificial parts form the joint, relying on the surrounding muscles and ligaments for support and function.

How Will I Know If My Incision Is Infected

After surgery, you will notice discolored skin, some swelling and drainage around your incision. This is normal. If you experience painful redness, abnormal swelling or thick, bad smelling drainage from your incision, you might have an infection. A temperature over 101°F also could indicate an infection.

Similar Conditions That Affect The Knee

Meniscus tear

Sometimes patients with knee pain don’t have arthritis at all. Each knee has two rings of cartilage called “menisci” . The menisci work similarly to shock absorbers in a car.

Menisci may be torn acutely in a fall or as the result of other trauma or they may develop degenerative tears from wear-and-tear over many years. Patients with meniscus tears experience pain along the inside or outside of the knee. Sometimes the pain is worse with deep squatting or twisting. Popping and locking of the knee are also occasional symptoms of meniscus tears.

Since some of these symptoms may be present with arthritis and the treatment of arthritis is different from that of meniscus tears, it is important to make the correct diagnosis. A good orthopedic surgeon can distinguish the two conditions by taking a thorough history, performing a careful physical examination, and by obtaining imaging tests. X-rays and Magnetic Resonance Imaging scans may be helpful in distinguishing these two conditions.

Knee Joint Infections

Also called infectious arthritis or septic arthritis, a joint infection is a severe problem that requires emergent medical attention. If not treated promptly knee infections can cause rapid destruction of the joint. In the worst cases they can become life-threatening.Symptoms of a knee joint infection include:

  • severe pain
  • fevers and

Again, a joint infection is a serious condition that requires immediate medical attention.

Learn What To Expect And How To Prepare From The Doctors Who Perform This Operation Every Day And The Patients Who Have Been Through Knee Surgery Successfully

If your knee arthritis has gotten so bad that your medication and physical therapy are no longer enough to keep the pain at bay or prevent mobility issues, it is a good time to consider knee replacement surgery. The procedure has come a long way from the extended hospital stays, bed rest, and narcotics-based pain relief of the past.

Fifteen to 20 years ago we told patients to wait until they could no longer take the pain of osteoarthritis to consider surgery, but thats not the case anymore, says P. Maxwell Courtney, MD, assistant professor of orthopaedic surgery at the Rothman Orthopaedic Institute at Thomas Jefferson University Hospital in Philadelphia. With todays advances, minimally invasive techniques, and accelerated rehab and recovery protocols, we now tell patients if the pain is limiting your daily activities and youve exhausted conservative options like injections and physical therapy its time to consider surgery.

That was certainly the case for Sharon Barnes, a teacher from Maine whose pain got so bad she couldnt sleep. My doctor said I had osteoarthritis in both knees it was literally bone on bone, she remembers. We did hyaluronic acid injections, and that got me about a year then didnt work as well. Thats when we started discussing surgery.

Getting Ready To Go Home

Before you go home, you will need to:

  • Be able to move or transfer in and out of bed, in and out of chairs, and off and on the toilet without help and safely
  • Bend your knees almost to a right angle or 90°
  • Walk on a level surface with crutches or a walker, without any other help
  • Walk up and down some steps with help

Some people need a short stay in a rehabilitation center or a skilled nursing facility after they leave the hospital and before they go home. During the time you spend here, you will learn how to safely do your daily activities on your own. You will also have time to build strength while you recover from your surgery.

Should I Have Knee Replacement Surgery

You might be a candidate for knee replacement surgery when other treatments no longer relieve severe pain and loss of function. Joint pain and immobility usually occur when the cartilage that protects and cushions the joints wears down. When this happens bones rub directly against each other, causing further damage and pain.

Not everyone is a candidate for knee replacement surgery. Your overall health is taken into account. If you have a history of other health problems such as heart attack, stroke or diabetes, surgery might not be right for you.

  • Blood tests – to check that you aren’t anaemic and that your kidneys and liver are working well enough for you to undergo the operation.
  • Urine test – to make sure you haven’t got a urine infection and that there isn’t any glucose in your urine.
  • Blood pressure.
  • Infection screen – this includes looking for meticillin-resistant Staphylococcus aureus . MRSA is a germ that is difficult to treat and can cause complications of a knee replacement.
  • A heart tracing .

What Are Recent Advances In Knee Replacement Surgery

Minimally invasive surgery has revolutionized knee replacement surgery as well as many fields of medicine. Its key characteristic is that it uses specialized techniques and instruments to enable the surgeon to perform major surgery without a large incision.

Minimally invasive knee joint replacement requires a much smaller incision, 3 to 5 inches, versus the standard approach and incision. The smaller, less invasive approaches result in less tissue damage by allowing the surgeon to work between the fibers of the quadriceps muscles instead of requiring an incision through the tendon. It may lead to less pain, decreased recovery time and better motion due to less scar tissue formation.

Currently this less invasive procedure is performed by only a small percentage of orthopedic surgeons in North America. Researchers continue looking at the short-term and long-term benefits of minimally invasive versus traditional knee replacement surgery.

Revision Knee Replacement Surgery

If the prior knee replacement component doesnt work for a longer time then it must be replaced to avoid any physical problem. You can opt for a second surgery known as revision total knee replacement which becomes essential if the initial surgery fails to prove effective.

The wear-and-tear on components, infection, component loosening and knee joint problems are the most common cause for revision surgery. Other reasons are mostly knee stiffness and bone fractures.

Can Rehabilitation Be Done At Home

All patients are given a set of home exercises to do between supervised physical therapy sessions and the home exercises make up an important part of the recovery process. However, supervised therapy–which is best done in an outpatient physical therapy studio–is extremely helpful and those patients who are able to attend outpatient therapy are encouraged to do so.

For patients who are unable to attend outpatient physical therapy, home physical therapy is arranged.

    After a period of 15 to 20 years, general wear and tear may loosen the implant. Depending on the patient, this may cause no symptoms, or it may cause any of the following:

    • pain
    • knee instability
    • infection

    When these symptoms arise, orthopedic surgeons recommend having to replace the original implant. Infection, especially, requires a prompt revision surgery.

    Why Must I Take Antibiotics For Dental Work Or Other Surgical Procedures

    Taking antibiotics is a precaution to help ensure that your new artificial joint does not become infected. Additional surgeries or dental work increases the chances of infection.

Please let your dentist or physician know that youve had joint replacement surgery. This is important no matter how small or straightforward the procedure.

    What Happens After Knee Replacement Surgery

    The average hospital stay after knee joint replacement is usually three to five days. The vast majority of people who undergo knee joint replacement surgery have dramatic improvement.

    How Long Will My New Joint Last

    In recent years, improvements in medical equipment and surgical techniques have meant that many knee replacements last longer than they did in the past.

    A new study looking at over 6,000 people who have had knee replacement shows:

    • More than 4 in 5 people who have total knee replacements can expect them to last for at least 25 years.
    • 7 in 10 people who have a unicompartmental knee replacement can expect it to last for at least 25 years.

    Clearly this will vary between different people, and you still need to take care of your new knee.

    Strengths And Limitations Of This Study
