What causes arthritis of the knee?

Experts have identified some genes that might cause arthritis, including arthritis of the knee. They predict that there are more genes not yet discovered. You could have a gene linked to arthritis without knowing it and a virus or injury could trigger arthritis of the knee.

Though the cause is unknown, some risk factors increase the possibility of arthritis of the knee. Risk factors of osteoarthritis, specifically, include:

• Age. Osteoarthritis happens to older adults more often than younger adults and children.
• Bone anomalies. You’re at a higher risk for osteoarthritis if your bones or joints are naturally crooked.
• Gout. Gout, also a type of inflammatory arthritis, might lead to osteoarthritis.
• Injuries. Knee injuries can cause arthritis of the knee.
• Stress. A lot of stress on your knees from jogging, playing sports or working an active job can lead to osteoarthritis of the knee.
• Weight. Extra weight puts more pressure on your knees.
