The knee joint is the largest of the body’s joints, and its well-being is essential to the performance of simple, daily activity. The knee joint is composed of three bones: in the upper section, the hip bone (Femur), in the lower section, the shin bone (Tibia), and in the center the kneecap (Patella). The sections of bone inside the joint itself are covered with a soft, smooth layer, called cartilage.
The job of the cartilage is to help in the smooth and better movement of the joint.
Between the bones is a “shock absorber” called meniscus.
The joint is held stable by a number of strong ligaments.
The most common reason for chronic pain, and restriction of movement of the joint, is the long-term inflammation of the joint (Arthritis). There are different types of inflammation; the most common are:
Osteoarthritis
Rheumatoid arthritis
Post-traumatic inflammation
Of the three inflammations, the most common is osteoarthritis. This is, in fact, a degenerate, erosive disease of the joint, that also has an inflammatory element. This phenomenon is more widespread in people over the age of 60. The cartilage which covers the surfaces of the joint, is eroded and disappears, and the exposed bones rub against each other, and cause severe inflammation, which is expressed by pain, stiffness and restriction in the movement of the knee.
We remove all the damaged surfaces of the bone and the cartilage in the area of the joint, and replace them with plates made from metal.
In the surgery, we release and balance the knee’s soft tissue and ligaments.
We attach the metal plates to the bone by means of special bone glue, called cement.
Between the metal plates, we place a hard, plastic spacerd, in order to allow smooth and better movement of the joint.

For the most part, the treatment of the disease is not surgical. Particularly in the initial stages, the majority of the patients will react best to conservative treatment, such as:
When is it recommended that surgery should be considered?
When conservative treatment fails, and the level of pain constantly and significantly harms he quality of life, we begin to consider surgical intervention. The harm caused to the quality of life is an individual measure, and so the decision on surgery is, at the end of the day, that of the patient. The disease is characterized by ups and downs, but, for the most part, progresses and recedes, in a constant manner
Nevertheless, how will we know when the time has come for surgery?
We use an plate for the hip bone, made from cobalt-chromium
A metal plate for the shin bone, made from cobalt-chromium
Hard, plastic spacer (polyethylene)
The implant is one of the most advanced on the market, with characteristics such as, special design (guarded by patent), multiple possibilities of movement, strength and quality of materials, that allow the patient smooth and stable movement of the knee.
