The presence of knee pain may prevent the simplest things make the day such as walking, bending over or up and down stairs. Today, technical advances in medicine give us the ability to change his artificial knee for another. The goal of total knee is back to their daily activities with decreased pain.

The reasons why there is pain in the knee can be manifold: osteoarthritis, which means wear of the joint, or rheumatoid arthritis, inflammatory diseases, fractures, knee, etc..

In addition to the knee, may have affected other joints of your body that may need surgery.

Arthroscopy is performed through small incisions, giving the surgeon a clear view inside the knee. This helps us diagnose and treat problems in the knees. During the procedure, the surgeon introduces the arthroscope, an instrument with a small camera the size of a pencil in the knee joint.
Technical advances have led to high-definition monitors and high resolution cameras. These and other improvements have made arthroscopy is a very effective tool to treat knee problems.

The arthroscope sends images to a television monitor. On the monitor, the surgeon can see the knee structures in great detail.

The surgeon may use arthroscopy to touch, remove or repair damaged tissue. Therefore, small surgical instruments are inserted through other incisions around the knee.

The total hip prosthesis is an operation designed to replace the hip joint that is damaged, usually by arthritis. The hip joint is a spherical joint. The sphere is formed by the head of the thigh bone (femur) and perfectly structured with a cavity that is in the pelvis (acetabulum).

The operation of total hip replacement involves replacing the femoral head worn by a sphere that is attached to a stalk or stem (this is called prosthesis), and placed in the cavity of the pelvis (acetabulum) a cup made of a special plastic: polyethylene. These two components can be fixed to bone by a special cement called Metilmetacrilato.

Osteoarthritis of the hip is generally a disease of elderly, but also can affect young people as a result of rheumatoid arthritis, hip fractures or other problems, such as necrosis of the femoral head.
