Lay Down And Elevate The Leg Above The Level Of The Heart

What is knee replacement surgery?

Elevating the surgical leg above the level of the heart contributes to reducing the swollen foot after surgery. As a rule, legs should be elevated while seated or reclining, so excess fluid does not collect around the damaged area.

After a leg injury, you are more likely to develop a dangerous blood clot if you dont elevate your leg, particularly if you spend most of your time sitting or lying in bed. Prop up injured areas while sleeping with soft pillows.

Total Knee Replacement Facts

  • Patients with severe destruction of the knee joint associated with progressive pain and impaired function may be candidates for total knee replacement.
  • Osteoarthritis is the most common reason for knee replacement operation in the U.S.
  • Risks of total knee replacement surgery have been identified.
  • Physical therapy is an essential part of rehabilitation after total knee replacement.
  • Patients with artificial joints are recommended to take antibiotics before, during, and after any elective invasive procedures .

What Are The Potential Side Effects Of Anesthesia

Most anesthesia side effects are temporary and go away within 24 hours, often sooner. Depending on the anesthesia type and how providers administer it, you may experience:

  • Back pain or muscle pain.
  • Chills caused by low body temperature .
  • Difficulty urinating.
  • Pain, tenderness, redness or bruising at the injection site.

Technical Details Of Total Knee Replacement

Total knee replacement surgery begins by performing a sterile preparation of the skin over the knee to prevent infection. This is followed by inflation of a tourniquet to prevent blood loss during the operation.

Next, a well-positioned skin incision–typically 6-7 in length though this varies with the patients size and the complexity of the knee problem–is made down the front of the knee and the knee joint is inspected.

Next, specialized alignment rods and cutting jigs are used to remove enough bone from the end of the femur , the top of the tibia , and the underside of the patella to allow placement of the joint replacement implants. Proper sizing and alignment of the implants, as well as balancing of the knee ligaments, all are critical for normal post-operative function and good pain relief. Again, these steps are complex and considerable experience in total knee replacement is required in order to make sure they are done reliably, case after case. Provisional implant components are placed without bone cement to make sure they fit well against the bones and are well aligned. At this time, good function–including full flexion , extension , and ligament balance–is verified.

Finally, the bone is cleaned using saline solution and the joint replacement components are cemented into place using polymethylmethacrylate bone cement. The surgical incision is closed using stitches and staples.

What Causes Pain After Knee Replacement Surgery

Researchers continue to study the many causes of pain after knee replacement surgery. Some are biological and due to conditions present before surgery, while others are due to complications that arise during surgery.

On the biological side, patients suffering from arthritis may experience increased sensitivity because of the ongoing pain that was present before surgery. As well explain below, inflammatory responses and allergy-related problems can also contribute to persistent pain. Another source of pain is referred pain originating from the hip due to a change in alignment.

If you are experiencing ongoing pain after knee replacement surgery, but do not have a medical history of arthritis or the previously mentioned issues, you may be dealing with surgical complications. While your doctor will take steps to prevent problems, its still possible for these to rare issues to occur:

  • Infection
  • Instability
  • Stiffness

Remember to stay open and honest with your doctors. This will help them properly diagnose and treat the problem to get you the pain relief youre looking for.

What Not To Do After Knee Replacement

After undergoing a partial or total knee replacement, there are certain movements to refrain from to avoid re-injuring your knee or causing pain.

Avoid any risk of falling After knee surgery, it will take a while before you regain strength and balance in the leg, making you more likely to experience a fall. Avoid activities like climbing ladders and take care to hold on to handrails when using stairs. Hiking or walking on the uneven ground should also be avoided until your knee is properly healed.

Dont sit for long periods Sitting for long periods after knee replacement surgery is correlated with a higher risk of blood clots. Make sure youre getting enough light activity to support healing after your operation.

Running Running puts three times the amount of pressure on the knee as walking. Avoid running while youre healing from knee replacement surgery until cleared to do so by your doctor.

But Regional Anesthesias Advantage Over General Doesnt End There

Additional benefits from the regional include better postoperative pain control, and decreased anesthesia side effects , continues Dr. Fisher.

Regional options include peripheral nerve blocks, spinal anesthetic, and epidural anesthesia.

Depending on the hospital and anesthesiologists abilities or competency at administering regional anesthesia, local physicians may have preferences.

If a patient wanted regional anesthesia, I would think the surgeon would be agreeable to having it provided.

Dr. Fisher has been involved in research and development of total hip and knee implants and has had numerous articles published in professional journals, and has participated in many research projects.

Lose Weight To Lessen Stress On Your Knees

Extra weight puts pressure on the knees and increases stress on the joint, increasing pain and making it hard to exercise. Research compiled by the Johns Hopkins Arthritis Center confirms that carrying extra pounds raises your risk of developing knee arthritis and speeds up the destruction of cartilage that cushions the joint.

Its not easy, but losing weight can help, whether youre dealing with arthritis in one or both knees. If you are overweight or obese, consulting with a nutritionist or a bariatric specialist may be the right place to start.

  • Use a handrail where possible with a walking aid in the opposite hand
  • If going down stairs, move the crutch or stick onto the lower step, put your weight on the crutch or stick as you move your operated leg onto the step alongside it
  • Bring your non-operated leg onto the same step and repeat
  • Do the opposite on the way back up.

    Total Knee Replacement Procedure

    During a total knee replacement, the top of your shin bone and bottom of your femur are resurfaced with plastic or metal parts, according to an article from Hopkins Medicine. Knee replacements are made to reduce pain that you can get from degeneration of the joint.

    Cartilage may wear down, which results in bone-on-bone contact in your knee. When your bones rub together, theyre slowly damaged and cause more pain. Putting a smooth metal surface over the bones or replacing a part with smooth plastic can get rid of your knee pain.

    Leg Swelling Years After Surgery

    Although swelling may occur up to six months after knee replacement, if it occurs longer than that, its a medical emergency, and you should visit your surgeon right away. Post-operative swelling years after surgery may indicate the following medical conditions:

    • Prosthetic joint infection
    • Deep vein thrombosis

    Prosthetic joint infections can occur immediately after surgery, weeks/months later, or even years later. Prosthetic joints that are infected require radiological and blood examinations, as well as revision surgery.

    Following are the symptoms that indicate swelling is due to prosthetic joint infection.

    • Redness
    • Fluid discharge
    • Inflammation

    Besides infection, deep vein thrombosis may also result in a swollen foot. A blood clot forms in the veins of the legs, causing this condition. Vein thrombosis is a significant side effect after knee replacement. To avoid this condition, doctors advise you to do ankle pumps frequently and start moving asap. In most cases, a patient is able to walk within one to two days following surgery.

    These symptoms suggest thrombosis is the cause of your swelling:

    • Pain that throbs or cramps
    • Warmth around the affected area
    • Discoloration or redness
    • Edema

    Conventional Treatment Methods Of Knee Pain

    Knee pain is treated in a variety of ways. Once the cause is diagnosed using proper techniques, a treatment plan is set in motion. Doctors use information such as a patients medical history, overall health, activity level, and comfort level to create a treatment plan that is unique to each patient. In the beginning, these plans typically enact the RICE method. This stands for Rest, Ice, Compression, and Elevation. Sometimes patients also take over the counter NSAIDS such as ibuprofen. Pain is often caused by a form of inflammation, so these methods can help subside the pain.

    If these less invasive methods fail to relieve pain, doctors will turn to slightly more intense treatment methods such as physical therapy or corticosteroid injections. Physical therapy seeks to strengthen muscles surrounding an injury and increase a patients range of motion. Corticosteroid injections are used to inject a powerful anti-inflammatory agent directly into the pain area. This is most often successful at relieving pain in the short-term but has been proven to damage tissue over time. Corticosteroid injections are not considered a long-term solution to knee pain.

    After undergoing slightly more invasive treatment methods and still failing to see results, doctors may discuss surgery as an option. Initial surgeries for knee pain are less invasive than a total knee replacement. These surgeries may include:

    Implanting The Tibial Component

    Total knee replacement

    The bottom portion of the implant, called the tibial tray, is fitted to the tibia and secured into place using bone cement. Once the tray is in place, the surgeon will snap in a polyethylene insert to sit between the tibial tray and the femoral component, and act as a kind of buffer. This insert will provide support for your body as you bend and flex your knee.

    Knee Replacement Recovery Time And Recuperation

    Total knee replacement surgery generally takes about 60 to 90 minutes, but you should expect to be in the operating room for over two hours. Rehabilitation will begin within 24 hours of surgery.

    After your surgery, the nursing staff will position you in bed and help you turn until you are able to move on your own. You may have a pillow between your legs if ordered by your surgeon.

    Very soon after surgery, a physical therapist will come to your room to teach you appropriate exercises and review your progress. Gentle exercises to improve your range of motion can help prevent circulation problems as well as strengthen your muscles.

    Your rehabilitation program will begin as soon as you are medically stable and there are orders from your doctor to begin postoperative mobility. All patients begin rehabilitation within 24 hours of their surgery. Your motivation and participation in your physical therapy program is key to the success of your surgery and recovery. The physical therapist will assist you in the following activities:

    • sitting at bedside with your feet on the floor
    • transferring in and out of bed safely
    • walking with the aid of a device
    • climbing stairs with aid of a device

    What Is A Meniscectomy

    A meniscectomy is an outpatient, elective surgery to remove the torn meniscus in your knee. Its typically done as an arthroscopic procedure. This involves small incisions, about a centimeter long, that your surgeon used to insert an arthroscope and small instruments for the removal of part or all of the meniscus.

    Types of meniscectomy surgeries include:

    • Partial meniscectomy: Removes a small piece of the torn meniscus
    • Total meniscectomy: Removes the entire meniscus

    In most cases, a partial meniscectomy is done to try to preserve as much of the cartilage as possible. Removal of an entire meniscus may increase the risk of arthritis about 10 years later. Thats because the meniscus helps decrease stress on the knee and provides shock absorption, stability, and joint lubrication. Without the meniscus, the impact of stress on the knee with activities is three times higher.
