Knee bursitis is inflammation of one of the knee bursae. A bursa is a fluid-filled sac that surrounds joints or tendons, which reduces friction by cushioning muscles, tendons, and bones that move across each other. Carpet layers, gardeners, and other people who are on their knees a good amount of time most commonly develop knee bursitis. Sports injury can also lead to bursitis.
Symptoms of bursitis often include swelling, redness, and pain around the knee joint.
To diagnosis the condition, your doctor will examine your knee to determine if you have bursitis. A needle and syringe may be used to obtain a sample of fluid from the bursa to rule out infections and to find the cause of the bursitis. X-rays and blood tests may also be indicated.
Rest, ice, and elevation of the affected leg are helpful for knee bursitis. Non-steroidal pain medications may also be used to reduce the pain and swelling. In severe cases, your doctor may recommend that your bursa be removed surgically.
To prevent knee bursitis, wear knee pads, reduce the amount of time spent on your knees, and apply ice to your knees after a workout.
