Total Knee Replacement


What is Total Knee Replacement?

A Total Knee Replacement is a surgical procedure whereby the knee joint is replaced with artificial material. The knee is a hinge joint which provides motion at the point where the thigh meets the lower leg. During a total knee replacement, the end of the femur bone is removed and replaced with a metal shell. The end of the lower leg bone is also removed and replaced with a channeled plastic piece with a metal stem. Depending on the condition of the kneecap portion of the knee joint, a plastic “button” may also be added under the kneecap surface.

Common Causes of Knee Pain and Loss of Knee Function

  • Osteoarthritis usually occurs in people 50 years of age and older and often with a family history of arthritis. The cartilage that cushions the bones of the knee softens and wears away due to wear and tear. The bones then rub against one another, causing knee pain and stiffness.
  • Rheumatoid arthritis is a disease in which the synovial membrane becomes thickened and inflamed, producing too much synovial fluid that overfills the joint space. This inflammation can damage the cartilage and eventually cause cartilage loss, pain, and stiffness.
  • Traumatic arthritis can follow a serious knee injury. A knee fracture or severe tears of the knee ligaments may damage the articular cartilage over time, causing knee pain and limiting knee function.


Is Total Knee Replacement for You?

Total knee replacement surgery is considered for patients whose knee joints have been damaged by either progressive arthritis, trauma, or other rare destructive diseases of the joint. The most common reason for knee replacement in the United States is severe osteoarthritis of the knees. Decisions regarding whether or when to undergo knee replacement surgery are not easy. Patients should understand the risks as well as the benefits before making these decisions.

What are the risk of Total Knee Replacement?

Risks of total knee replacement include blood clots in the legs that can travel to the lungs. Pulmonary embolism can cause shortness of breath, chest pain, and even shock. Other risks include urinary tract infection, nausea and vomiting, chronic knee pain and stiffness, bleeding into the knee joint, nerve damage, blood vessel injury, and infection of the knee which may require re-operation.

Sign and Symptoms of Blood Clot

When there is blood cot in the legs:

  • Increasing pain and swelling in your calf, ankle and foot
  • Tenderness around your knee

When there is blood clot in your lung:

What is Knee Pain?

Knee pain is the most common injury that one can sustain. As it is the largest joint in the body, The knee cap or patella is a bone within the tendon of the quadriceps muscle. The patella forms a joint with the femur that shares the same capsule as the joint between the femur and tibia. The latter joint has two half-moon-shaped pieces of cartilage called menisci that both guide the bones as they move and take about 60 percent of the weight going through the knee. In addition, there are a large number of muscles, ligaments, and tendons acting to move or stabilize the knee. Some causes of knee pain are obvious while others may require in depth examination and special investigations to diagnose.

Prevention for Knee Pain

  • Increase your activity level gradually
  • Always warm up by streching your quadriceps and hamstrings before and after exercising
  • Wear proper footwear for your foot shape and mechanics
