Causes of OA

In many cases, it’s hard to identify a clear cause of OA. But research suggests some things may put certain joints at more risk. For example:

• Knees – a previous knee injury, being overweight or jobs involving kneeling, climbing or squatting³.
• Hips – a previous hip injury, being overweight, or jobs involving heavy lifting, such as farming³.
• Hands – a family history of OA in the family³.
