Causes of arthritis in elderly population

Experts aren’t sure what causes osteoarthritis. Primary osteoarthritis usually develops slowly as you age. As you get older, normal wear and tear on your joints might contribute to their cartilage breaking down.

Anything that directly damages your joints can also cause osteoarthritis, including:

• Sports injuries.
• Falls.
• Car accidents.
• Health conditions that affect your joints, like Ehlers-Danlos syndrome or joint hypermobility syndrome.

Other forms of arthritis (specifically inflammatory arthritis) can cause osteoarthritis, including:

• Rheumatoid arthritis.
• Gout.
• Psoriatic arthritis
