Knee Arthritis

Arthritis, also called osteoarthritis or degenerative arthritis, involves the swelling and damage of the joints. It causes pain, stiffness and limited movement. Since knees are the primary weight- bearing joints in the body, they are most at risk for osteoarthritis. Risk factors include age, heredity, injury and obesity.

Damaged Cartilage

Cartilage is a smooth, protective joint tissue that cushions the bones and allows joints to move freely.  Cartilage can deteriorate over time.  As it loses its cushioning ability, heavy use or injury may increase its rate of deterioration.

Cartilage Loss

Eventually, as cartilage wears away completely, bone rubs against bone.

Bone Spurs

Over time, lumpy growth of bone called bone spurs or osteophytes form along the edges of the joint.

Symptoms

An arthritic knee may feel stiff, and leg motion may be limited.  Standing or walking for long periods may make pain in the joint worse.  Severe arthritis may create pain at all times, even when at rest.  If the cartilage wear is only on one side of the knee, the sufferer may become bow-legged or knock-kneed.

Treatment

In the early stages of arthritis, medication, weight loss and other lifestyle changes may relieve some symptoms.  When arthritis becomes bad enough to interfere with normal activities, arthroscopic or surgical correction may be needed.  In severe cases, total or partial joint replacement with metal or ceramic components may be required.
