Osteoarthritis (OA)

Osteoarthritis (OA) is a type of joint disease that results from breakdown of joint cartilage and underlying bone. It is also known as degenerative arthritis or osteoarthrosis. Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It is mainly caused by aging joints, injury, and obesity. The most commonly involved joints are those near the ends of the fingers, at the base of the thumb, neck, lower back, knees, and hips. The most common symptoms are joint pain and stiffness. OA is the most common cause of a joint effusion of the knee.

Risk Factors

2. Obesity : Carrying extra body weight contributes to osteoarthritis in several ways. It puts added stress on weight-bearing joints, such as your hips and knees.
3. Sex : Women are more likely to develop osteoarthritis, though it isn't clear why.
4. Joint injuries : Injuries, such as those that occur when playing sports or from an accident, may increase the risk of osteoarthritis.
5. Genetics : Some people inherit a tendency to develop osteoarthritis.
6. Bone deformities : Some people are born with malformed joints or defective cartilage, which can increase the risk of osteoarthritis.
7. Others :
- Diabetes
- Inflammatory diseases
- Alkaptonuria
