Causes of Osteoarthritis

Osteoarthritis is a common degenerative joint disease that affects millions of people worldwide. It is caused by the breakdown of cartilage, which is the cushioning material that covers the ends of bones and allows them to move smoothly against each other. Here are some of the main causes of osteoarthritis:

1. Age: The risk of developing osteoarthritis increases with age, as cartilage tends to wear down over time.
2. Genetics: Some people may be genetically predisposed to developing osteoarthritis.
3. Obesity: Being overweight or obese puts extra stress on the joints, which can lead to cartilage damage and osteoarthritis.
4. Joint injuries: Injuries to the joints, such as a fracture or a ligament tear, can increase the risk of osteoarthritis.
5. Repetitive stress: Repetitive stress on a joint, such as from certain occupations or sports activities, can cause wear and tear on the joint and increase the risk of osteoarthritis.
6. Bone deformities: Some people may be born with bone deformities that can increase their risk of developing osteoarthritis later in life.
7. Other medical conditions: Certain medical conditions, such as rheumatoid arthritis, gout, and Paget’s disease of bone, can increase the risk of developing osteoarthritis.
