Knee Pain

It is a pain that is felt in or around the knee and indicates a condition that affects the knee joint itself or the soft tissue around the knee.

Common causes:

  • Sudden injury
  • Overuse injury (sprains or strains)
  • Heavy physical activity
  • Sitting in a constrained area or on knees for a prolonged period
  • An underlying condition, such as arthritis

Treatment will vary depending on the cause. Knee injury is likely to cause pain, swelling, and stiffness.


Lose the extra flab! long-term knee pain can be controlled better if you lose excess weight. For new pain, resting, applying ice several times a day, keeping the injured area elevated and wrapping the area with an elastic bandage may help. Avoiding squatting and climbing stairs.

Consult a doctor if:

  • There is redness, swelling, warmth or significant pain
  • You develop a fever
  • The pain is constant
  • The pain worsens

Immediate attention is needed if:

  • The knee injury was preceded with a popping sound
  • The knee looks deformed
  • The pain is severe
  • Sudden swelling is noticed
  • You cannot move your knee

What is Knee Replacement Surgery?

Knee Replacement Surgery may be considered if performing even acts of daily living become difficult. Simple movement taking your pet for a walk, climbing a flight of stairs, or even getting out of a chair can sometimes become difficult and painful. If you have tried medicines, injections, and physical therapy, and nothing seems to work, it would be advisable to consider knee replacement surgery.

Also known as arthroplasty, knee replacement surgery is a common bone surgery that can help ease the pain and improve movement. During surgery, the joint replacement surgeon carves away the damaged part of the knee and replaces it with an artificial joint made of metal or plastic, which is then attached to the thigh bone, shin, and kneecap with something like acrylic cement.

How Long Do They Last?

When replacement surgery first started in the early 1970s, the artificial joints were expected to last for about a decade. Now, however, modern implants can last as long as 20 years.

In which conditions is surgery recommended?

  • Osteoarthritis: The main objective of knee replacement surgery is to eliminate the pain and movement disorders caused by Osteoarthritis. A very common old-age problem, Osteoarthritis occurs when cartilage, the cushion between the knee and the bone joints, breaks down.
  • Rheumatoid arthritis: When the body’s immune system attacks and destroys the lining of the knee thus causing severe pain
  • Deformities: People with bowed legs or “knock-knees” may need surgery to restore the knee position
  • Knee injuries: A broken bone or torn ligaments around the knee may result in arthritis. Surgery can help in alleviating pain and restoring movement
  • Loss of blood flow: Doctors will recommend surgery if knee damage causes a halt in blood flow to the bones (a condition called either osteonecrosis or avascular necrosis)

Different Types of Surgery:

There are four main types of knee replacement surgery:

Total knee replacement: This is the most common. The surgeon replaces the end of the thigh bone with a metal shell and the connecting end of the lower leg bone with a channeled plastic piece with a metal stem.

Partial knee replacement: If only one side of the knee is affected by arthritis, partial replacement is possible. However, the surgery will succeed only if the knee ligaments are strong. This surgery can be performed through a smaller cut than is needed for total knee replacement.

Kneecap replacement: This replaces only the under-surface of the kneecap, often not advised by Doctors as total knee replacement surgery has a higher rate of success.

Complex (or revision) knee replacement: This procedure may be needed in severe conditions or if earlier surgeries have not yielded the desired result.
