Osteoarthritis of the Knee

Osteoarthritis, also known as the degenerative joint disease, is one of the main reasons of knee pain. It is experienced by people over 65 years of age, whereas, few people can experience this problem in a very young age.

Generally, the knee joint is comprised of three bones-femur, Tibia and patella. The ends of the bones are protected by a cushion termed as cartilage, which helps us while walking, running and jumping. But when this is damaged, it has very poor blood supply.

Why people get Osteoarthritis at younger age?

Anything that puts pressure and stress on the cartilage can damage it quickly. Obesity can place lot of stress on the knee, so it is required to carry out certain activities such as climbing and walking.

And, an injury to the knee can degenerate the cartilage. Genetics also play a major role in degenerating cartilage. As the cartilage wears away, the knee gets damaged. This leads to pain particularly while climbing stairs and when getting up from a sitting position.

Osteoarthritis is recognized through X-ray. The space between the bones is covered by cartilage becomes narrower as the degeneration of cartilage takes place.

As the bone under knee is damaged, the formation of bone spurs take place. Due to the degeneration of cartilage, the knee gets decayed and becomes stiffed. Then the swelling takes place. In some cases, the swelling is excessive and the knee is filled with a fluid. This condition is termed as Knee effusion.

Knee effusion builds pressure on the knee, which makes it very difficult even to bend the knee. In the case of big effusion, the fluid can be taken out. This process is called knee aspiration.

Osteoarthritis treatment is classified into different types. Depending on the severity of the problem, you can go for the appropriate treatment.
