Osteoarthritis

What is Osteoarthritis?

Osteoarthritis, or OA, is the oldest and most common form of arthritis. In osteoarthritis, changes occur in both the cartilage and bone of joints that lead to joint pain, stiffness and swelling. OA also is known by many other names, such as degenerative joint disease, arthrosis, osteoarthrosis or hypertrophic arthritis. Risk factors for OA include being overweight, joint injury, muscle weakness,having other forms of arthritis, and heredity.


What are the causes of Osteoarthritis?

The cause of osteoarthritis is not known, but researchers have shown that there are several factors that increase your risk of developing OA. These factors include heredity, obesity, injury to the joint, repeated overuse of certain joints, muscle weakness, nerve injury and aging.


What are the symptoms of Osteoarthritis?

OA symptoms tend to build over time rather than show up suddenly. Symptoms can vary depending on which joint is involved, as well as your age, weight, joint alignment, fitness and physical activity level. However, some common symptoms include:

  • persistent or recurring pain, aching or tenderness in and around a joint
  • stiffness and limited range of motion in a joint
  • mild swelling around a joint
  • clicking or cracking sound when a joint bends
  • enlargement or changes to the shape of a joint

Joints affected by osteoarthritis usually hurt or feel stiff during or after use. Stiffness after not moving for a while is also common. For example, you may find it hard to use the joint in the

How is it diagnosed?

It’s possible that your doctor can diagnose your OA. To begin with, he’ll ask you to describe your symptoms and discuss how they’re affecting your life. Then he’ll ask about your personal and family medical history.

Additional procedures, such as X-rays, may be recommended to help confirm the diagnosis, rule out other causes of pain and assess joint damage. Joint aspiration, a procedure in which fluid is drained from the affected joints and examined, also may be used to rule out other forms of arthritis such as gout. Your doctor may conduct blood tests to rule out other diseases that cause joint pain such as rheumatoid arthritis.


What treatments are there?

Your treatment plan should be based on how severe your disease is, which joints are affected, your symptoms and any other medical problems. Your age, occupation and everyday activities also should be considered. The plan will likely include many things you can do to manage your OA, such as physical and/or occupational therapy, regular physical activity, weight control if you’re overweight and medication. If these measures don’t help, surgery may be considered for certain joints, like hips or knees.

The goals of OA treatment are:

  • controlling pain and other symptoms
  • improving and preserving joint function
  • weight loss (if overweight) and maintaining a healthy body weight
  • optimizing overall health, well-being and quality of life
