While many osteoarthritis risk factors—being female, older and having other diseases that affect the bones and joints—cannot be changed, you can work on several other risk factors to lower your risk of developing the condition:

• Obesity. Losing extra weight and exercising can help people with osteoarthritis. Most importantly, weight loss may reduce the risk of developing osteoarthritis of the knee in overweight or obese people.

• On-the-job injuries. Taking precautions to avoid repetitive joint use and resulting joint injury in the occupational setting can help prevent osteoarthritis.

• Sports injuries. Using recommended prevention strategies (warm-ups, strengthening exercises and appropriate equipment) helps to avoid joint injuries and damage to ligaments and cartilage, all of which can increase your risk of osteoarthritis.
