Doctors treat bursitis of the knee using over-the-counter pain medication, antibiotics or steroid injections, according to Drugs.com. When these methods are ineffective, the doctor may perform surgery to remove the bursa.
Bursitis is the inflammation of the bursa, a fluid-filled sac that decreases rubbing and irritation between tissues. Repetitive motion, injury or infection are common causes of bursitis. Proper stretching before exercise or work helps to prevent bursitis, according to WebMD.
There are 11 bursa in each knee, according to Mayo Clinic. Knee bursitis is painful and often limits the movement of the knee. Resting the knee, using ice and compression, and elevating the knee can help to relieve the pain. However, if the patient suffers bursitis due to an infection, the doctor prescribes antibiotics. Other options include aspiration, the removal of fluid from the bursa with a hypodermic needle or steroid injections to reduce pain. With severe bursitis that does not respond to other treatments, doctors may recommend surgery.
An individual with bursitis should contact his caregiver if the pain and swelling of the affected joint increase or the symptoms do not respond to the treatment, reports Drugs.com. If the patient experiences fever with bursitis he should also contact his doctor. Without proper care, an infection that causes bursitis can spread to nearby tissues.
