Osteoarthritis of the Knee

Osteoarthritis of the knee is one of the most common forms of arthritis. Commonly referred to as “wear-and-tear” arthritis, osteoarthritis occurs when the knee joint’s cartilage gradually wears away, causing the bones to rub against each other. Bony bumps called bone spurs may also form in osteoarthritis of the knee.

Causes

Osteoarthritis of the knee is typically found in people over the age of 50 and is the result of aging. In most cases, it develops slowly and pain increases over time. Osteoarthritis can also affect younger people who experience an injury or those who put a lot of stress on their knees from work or sports. Obesity is another risk factor.

Symptoms

The most common symptoms of osteoarthritis of the knee are pain, swelling, and stiffness. The knee may feel weak or like it could buckle when standing and walking. It can also be difficult bending and straightening the leg. Symptoms usually get worse with overuse.

Diagnosis

Physicians will conduct a thorough examination and review symptoms and medical history. Joint swelling, redness, tenderness, pain, and range of motion are all factors that will be assessed before diagnosing osteoarthritis of the knee.

Treatment

In minor cases of osteoarthritis of the knee, conservative treatment options such as physical therapy, knee bracing, and weight loss are effective. Over the counter anti-inflammatory pain medications and corticosteroid injections may also be recommended. In advanced cases, surgery may be required.
