"The only way to protect yourself from appearance of knee-joint deforming arthrosis is the surgery for bow legs and knock knees correction."

Bow legs and knock knees are deformities that can lead to knee-joint movement abnormality and result in deforming arthrosis.

Bow legs (genu varum) - A condition where legs have deformity outward of natural legs position.

Knock knees (genu valgum) - A condition where legs have deformity inward of natural legs position.

Deforming arthrosis - A disorder of the knee joint, generally implying early joint surface damage.

Leg axis - Conventional axis that shows how the body weight distributes among leg joints.

Articular cartilage - A type of dense connective tissue. It can supply smooth surfaces for the movement of articulating bones.

Bow legs (genu varum) and knock knees (genu valgum) are deformities that are not only cosmetic defects. But they can also lead to knee-joint movement abnormality that may result in deforming arthrosis.

If we look at picture 1 we find out that normal body weight distribution is when the leg axis go straight through femoral head, center of the knee-joint and center of articulation of foot. In this case the body weight distributes naturally and articular cartilage of knee-joint have equal weight distribution at full surface. There is a natural position of knee-joint that allows to save the articular cartilage in health during years.

What happens when a person has bow legs or knock knees

Look at the picture 2. You could see that the legs axises go still straight through the femoral head and center of articulation of the foot but do not go through center of the knee-joint. So body weight distribution change and regarding the knee-joint one part of the knee have more loading than another. If bow legs there is more loading of inner part of knee-joint and if knock knee there is more loading of outer part of knee-joint. So articular cartilage of knee-joints have different weight distribution at surface that leads to its attrition in the part where the loading is maximum. In time the articular cartilage attrition leads to deforming arthrosis and a person feels pain in knee-joints. Appearance of deforming arthrosis usually happens in senior years - but sometimes it happens in middle age depending on individual health of each person.

The only way to protect yourself from appearance of knee-joint deforming arthrosis is the surgery for bow legs and knock knees correction. With the surgery the leg axis become natural position so articular cartilage of knee-joint get equal weight distribution at full surface and keeps its health in years. Also there is a cosmetic effect that lets a person feels himself or herself more comfortable around other people.
