Whom Should we Recommended for a Knee Replacement Surgery?

The most common reason for considering a knee replacement surgery is severe osteoarthritis of the knees. Patients whose knee joints are damaged by trauma or other joint destructive diseases are also recommended for knee replacement. People with stiff knees, who find it difficult to indulge in activities like walking are the other susceptible groups. Rheumatoid arthritis and traumatic arthritis are the other factors which can be taken into consideration. Patients suffering from haemophilia and gout can also be a group to consider. However, replacement options are only considered for patients who had tried and failed alternative methods of pain reliefs.

Knee Surgery

How is it diagonised ?
The need for a knee replacement surgery is diagonised after the physical examination of knee joints by the surgeon by assessing the mobility and stabilityof the joints. The Orthopaedic surgeon confirms the need for the surgery after the visualization of the X-ray reports which determines the severity of the patient’s knee damage.

What are the risks involved?
One of the risks associated with the replacement is the formation of the blood clots in the legs , leading to pulmonary embolism. This can be accompanied by chest pain. Other risks include bleeding into the knee joint and chronic knee pain . In certain cases it may lead to infection of the knee which in turn may lead to the requirement of reoperation. Stiffness of the joint or nerve damage are the other associated risks. Anesthesia associated risks can cause lung, liver or kidney damage. Nausea and vomiting due to pain medication are also common.

How worthwhile would be the knee implant?
After the Knee surgery , with the implanted prosthesis and physical therapy ,one can expect a relief from chronic pain of joints. Without the stiffness the legs can experience a natural motion. One can carry out their routine activities like walking with much ease.

11 Tips to Take Care About Total Knee Replacement Surgery – Dr.Simon Coffey

1. On the Road to Recovery
When it comes to knee replacement surgery, the procedure itself, while obviously important, is just one step in the process. What happens after the surgery—the recovery and rehabilitation—is just essential to the overall success of the procedure.

Total Knee Replacement Surgery Sydney

Here are some strategies to help guide you through recovery and rehabilitation.

2. Take Your Recovery and Rehab Seriously
It’s important to not let your routine slide. Use your continuous passive motion (CPM) machine as advised by your doctor, and perform all the exercises your physical therapist prescribes. Attend your follow-up appointments with your surgeon and go to all your physical therapy sessions, even when you don’t feel like it. Take medications as prescribed and do not stop any medication without checking with your doctor.

3. Improve Your Extension and Flexion
Bend and straighten your leg as much as possible. One way to improve your extension is to lay down, with a rolled towel placed underneath your ankle while lying down—try to keep your leg as straight as possible. You can improve your flexion by sitting on a chair and bending your knee back (i.e., curling your leg underneath the seat of the chair). Also, talk to your physical therapist to learn if they recommend continuing use of the CPM machine to help you expand your range of motion.

4. Avoid Unnecessary Stress on Your Knee
Avoid lifting heavy objects that could place an excessive amount of stress on your artificial knee—and possibly damage it. Also, when you turn to face a different direction, make sure you turn your entire body and avoid twisting your knee pain. It is important to monitor your form when you bend down, kneel, and sit. Perform these regular movements with your physical therapist, so that he or she can help you learn how to do them safely and efficiently.

5. Take Recommended Supplements and Vitamins
Talk to your doctor about vitamins or supplements that might help. One study found that 43 percent of patients scheduled to undergo orthopaedic surgeon have insufficient levels of vitamin D. Also, many orthopedic patients take iron to help replenish blood count after surgery. Since you might be compensating with your non-operated knee during the early stages of rehab, you may want to consider supplements that can aid in muscle recovery.

6. Wear Compression Stockings
If your doctor suggests that you wear compression stockings post-surgery, keep them on at night or while lying down. They can help reduce the risk of blood clots. Make sure you wear them until your doctor says that it’s okay to stop.

7. Keep the Ice and Heat On
Icing your knee replacement can reduce inflammation and pain. It is particularly effective for the first several days after surgery and during any flare up. After the initial swelling has decreased, you can alternate ice and heat—which relaxes the muscles and eases stiffness.

8. Minimize or Avoid Alcohol & Smoking
Avoid drinking alcohol if you are taking a blood thinner such as warfarin (Coumadin) or taking any narcotic pain medication. If you smoke, make an effort to cut back or stop. Smoking shrinks your blood vessels, which makes the healing process slower. Healthier lungs lead to higher blood oxygen levels—and faster healing.

9. Watch Your Weight
Keep your weight down. Extra pounds put greater pressure on your new knee Surgery, and can slow your recovery. Also, if you are overweight you can risk developing osteoarthritis in your other knee. Learn more about the connection between your weight and your new knee.

10. Go for Walks and Exercise Sensibly
Walking and exercise help strengthen the muscles in your legs and improve overall blood flow. Take outside walks as soon as possible and increase the distance a bit each day. Moving around the house doesn’t provide enough exercise. In addition, as your knee grows stronger, consider low impact activities like swimming, golf, gardening, and peddling on a stationary bike to aid in rehab.

11. Avoid High Impact Activities
As your knee grows stronger you may be tempted to resume your favorite sports. However, high impact activities like running, downhill skiing, and vigorous court games could cause serious pain and problems or damage your prosthetic device. Explore ways in which you can engage in the sports you like, without excessive impact. For example, try power walking instead of running, or doubles instead of singles tennis.

The Common Causes Of Severe Knee Surgery Pain – Simon Coffey

Most people experience knee surgery pain at some point in their lives. Sports, exercise, and other activities can cause muscle strains, tendinitis, and more serious injuries to ligaments and cartilage. For some, knee pain can be so severe that it limits daily activities. For others, mild knee pain may be a chronic hindrance to the active lifestyle they desire. In either case, chances are that you’re dealing with a knee problem that shouldn’t be ignored.


Knee Ligament Injuries
The ligaments are what connect your thigh bone to your lower leg bones. They hold your bones together and keep the knee stable. Knee ligament sprains and tears are very common sports injuries and can occur to the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and medial collateral ligament (MCL). Any of these injuries can result in severe knee pain and could require surgery.

Knee Cartilage Tears
Other injuries, including tears, can take place in the cartilage of the knee. Cartilage is a semi-hard (tough, but flexible) tissue that covers the end of your bones. Knee cartilage comprises the two menisci on either side of the joint: the medial meniscus, located on the inside of the knee and the lateral meniscus, positioned on the outside of the knee. You’ve probably heard the phrase “meniscus tear”. A tear in the knee cartilage is a common injury, and typically requires surgery.

Arthritis of the Knee
Arthritis is a common cause of severe knee pain and disability. Unfortunately, arthritis is a chronic degenerative condition that can eventually require surgery. The three most common types of arthritis are rheumatoid arthritis, post-traumatic arthritis, and osteoarthritis. In the case of any of these three, you may experience stiffness and swelling, and it may be hard to bend your knee.

Rheumatoid Arthritis of the Knee
Rheumatoid arthritis is an autoimmune disease that causes the tissue around the joint to become inflamed and thickened. Chronic inflammation often leads to damage and loss of cartilage. Rheumatoid arthritis represents only about 10 percent to 15 percent of all arthritis cases.

Post-Traumatic Arthritis
Post-traumatic arthritis can result after a serious knee injury, including bone fractures and ligament tears. These injuries can damage the cartilage in your knee over time and lead to pain, swelling, and stiffness.

Osteoarthritis of the Knee
The most common type of arthritis is osteoarthritis, which is a progressive wearing of the cartilage in the knee joint. It occurs more frequently in individuals 50 and older. After 50, the impact of osteoarthritis can worsen due to accumulated use and the wearing down of cartilage that occurs with age. Osteoarthritis of the knee causes pain, limited range of motion, stiffness of the knee, swelling of the joint, tenderness, deformity and weakness.

Causes of osteoarthritis include age, weight, genetics, previous injuries, infections, and illness (such as a tumor or gout). Osteoarthritis can also be caused by sports injuries and wear and tear resulting from physical work in occupations, such as construction and manufacturing.

Diagnosing Knee Pain
Doctors diagnose arthritis and other knee problems using x-rays and a physical evaluation. You will be asked about your pain level, knee flexibility and function, and general mobility. Medical professionals will also use special tests to identify the type of arthritis affecting your knee.

Treating Knee Pain from Arthritis
Knee pain usually becomes worse as arthritis progresses. Common treatments include: weight loss, strengthening exercises, wrapping, and pain relievers—such as acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs).

While osteoarthritis is the most common surgical patient diagnosis, those with severe pain from any type of arthritis may benefit from surgery, including a partial or total knee replacement. It’s crucial to discuss and explore all treatment options with your doctor before opting for surgery.

Revision Total Knee Replacement

Most knee replacements provide very good long term function for many years after implantation. The most recent figures from The AOANJRR (Australian Orthopaedic Association National Joint Replacement  Registry) reveal that the revision rate for Primary Total Knee Arthroplasty at 15 years is 7%. Most of these replacements have failed either as a result of infection or premature wear.

After a long period of time, a knee replacement can wear out. Sometimes the procedure to correct this problem is as simple as changing the polyethylene bearing insert in the knee – much like a retread on a car tyre. Other times a much more extensive procedure is required where all the major components of the knee are exchanged. Each of these procedures can renew the life of knee replacement for another 10-15 years.

Below is an example of a worn out polyethylene bearing which was able to be swapped out for a new one.

Another example of a much more extensive procedure appears below.


The decision as to whether to do the more minor operation or the larger one is best left to your specialist total knee replacement surgeon who will consider the pros and cons of each operation.

Knee Surgery: A Solution To Avoid Knee Arthritis

Painful knees are a common problem in middle-aged people and elders, and the most common cause of knee pain in this population is Knee Arthritis. There are few treatments for knee arthritis early can help alleviate pain and return people to their daily activities. As some point, arthritis of the knee begins to interfere with the quality of life to the point that something has to change. When treatments such as Anti-inflammatory medications, cortisone injections and physical therapy, do not improve the situation total knee replacement may be an option. The most general reason of chronic knee pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis and traumatic arthritis are the most common. Osteoarthritis generally occurs after age 50 and often in an individual with a family history of arthritis. The cartilage that cushions the bones of the knee softens and wears away. The bones rub together, causing pain and stiffness in the knee. Rheumatoid arthritis is a disease in which the synovial membrane becomes thickened and inflamed, producing too much synovial fluid over-fills the joint space. This chronic inflammation can damage cartilage and eventually cause cartilage loss, pain and stiffness. Traumatic arthritis can follow a serious knee injury. A knee fracture or severe tears in the ligaments of the knee can damage the articular cartilage over time, causing knee pain and limited function of the knee.

Recent Advances in Knee Joint Replacement Surgery: Minimally invasive surgery (MIS) has developed knee replacement surgery, and many fields of medicine. Its key feature is that it uses specific methods and instrumentation to let surgeons execute major surgery without any large cut. MIS requires a much smaller incision, three inches to five years, compared to standard approach and the incision, which is usually eight to twelve inches. The smaller, less invasive approaches result in less tissue trauma, allowing the surgeon to work between the quadriceps muscle fibers rather than requiring an incision through the tendon. It may lead to less pain, shorter recovery time and better motion due to reduced formation of scar tissue. When a full knee surgery is performed, the bone and cartilage at the end of the thighbone (femur) and upper shin bone (tibia) are removed. This is done with accuracy to craft accurate surfaces to accommodate the implant. A metal and plastic implant knee replacement are put to work as a new knee joint. Depending on the condition of the cartilage on the under surface of the kneecap, this may also be replaced.

The knee prosthesis implants can wear out over time. The implant is made of metal and plastic, and while these implants are designed to last many years, all of which take time. Studies have shown knee replacement implants are functioning well in 90-95% of patients between 10 and 15 years after the knee surgery. Most full knee replacements last 20 years and many of them last longer. However, it is important to understand that there are possible complications of knee replacement surgery may reduce the life of the implant. Because of this, total knee replacement should be reserved for elderly patients with significant symptoms of arthritis.
