Causes
Knee pain usually results from overuse, poor form during physical activity, not warming up or cooling down, or inadequate stretching. Simple causes of knee pain often clear up on their own with self care. Being overweight can put you at greater risk for knee problems.
Knee pain can be caused by:
- Arthritis -- including rheumatoid, osteoarthritis, and gout
- Baker's cyst -- a fluid-filled swelling behind the knee that may accompany inflammation from other causes, like arthritis
- Bursitis -- inflammation from repeated pressure on the knee, such as kneeling for long periods of time, overuse, or injury
- Connective tissue disorders such as lupus
- Dislocation of the kneecap

Prevention
- Increase your activity level slowly over time. For example, when you begin exercising again, walk rather than run.
- Always warm up before exercising and cool down afterward. Stretch your quadriceps and hamstrings.
- Replace your sports shoes often. Get good advice about proper footwear for your foot shape and mechanics. For example, if you pronate (land on the outside of your heel and turn your foot inward), consider anti-pronation footwear.
