A number of factors can increase your risk of having knee problems, including:
Mar. 29, 2013
- Excess weight. Being overweight or obese increases stress on your knee joints, even during ordinary activities such as walking or going up and down stairs. It also puts you at increased risk of osteoarthritis by accelerating the breakdown of joint cartilage.
- Biomechanical problems. Certain structural abnormalities — such as having one leg shorter than the other, misaligned knees and even flat feet — can make you more prone to knee problems.
- Lack of muscle flexibility or strength. A lack of strength and flexibility are among the leading causes of knee injuries. Tight or weak muscles offer less support for your knee because they don't absorb enough of the stress exerted on the joint.
- Certain sports. Some sports put greater stress on your knees than do others. Alpine skiing with its rigid ski boots and potential for falls, basketball's jumps and pivots, and the repeated pounding your knees take when you run or jog all increase your risk of knee injury.
- Previous injury. Having a previous knee injury makes it more likely that you'll injure your knee again.
