Osteoarthritis (OA) is a degenerative joint disease affecting an estimated 27 million Americans. This disease is caused by the deterioration of cartilage. This is the smooth, elastic tissue that protects joints and provides the lubrication necessary for normal joint function.

OA is a top cause of disability in older people. The goal of osteoarthritis treatment is to reduce pain and improve function. There is no cure for the disease, but some treatments attempt to slow disease progression.

In diagnosing osteoarthritis, the foot and ankle surgeon will examine the foot thoroughly, looking for swelling in the joint, limited mobility and pain with movement. In some cases, deformity and/or enlargement (spur) of the joint may be noted. X-rays may be ordered to evaluate the extent of the disease.

Osteoarthritis is most common in people over the age of 65. According to the Arthritis Foundation, one in two adults will develop symptoms of knee osteoarthritis, one in four will develop hip osteoarthritis before the age of 85, and one in 12 people over the age of 60 have osteoarthritis in their hands.

Keeping weight in control is very helpful for preventing osteoarthritis in the long-term. Excessive weight adds stress to weight-bearing joints such as the hips and knees. Osteoarthritis can be prevented if injuries are avoided. Proper occupational and sports equipment along with safety precautions can also prevent joint degeneration.
