Risk factorsBy Mayo Clinic staff
Knee bursitis is a common complaint, but the following factors may increase your risk of developing this painful disorder.
- Excessive kneeling. People who work on their knees for long periods of time — carpet layers, plumbers and gardeners — are at increased risk of knee bursitis.
- Participation in certain sports. Sports that result in direct blows or frequent falls on the knee — such as wrestling, football and volleyball — may increase your risk of knee bursitis. Runners may develop pain and inflammation in the anserine bursa, located on the inner side of your knee below the joint.
- Obesity and osteoarthritis. Obese women with osteoarthritis often develop bursitis involving the inner side of the knee below the joint.
- Impaired immune system. People who have medical conditions or who take medications that make them more susceptible to infection may have a greater risk of infectious (septic) knee bursitis. These conditions include cancer, diabetes, lupus, alcoholism and HIV/AIDS.
