Anserine Tendinobursitis Syndrome
(Goosefoot Bursitis; Pes Anserine Bursitis; Anserine Tendonitis)
Anserine tendinobursitis syndrome is a pain to the inner part of the leg, just below the knee joint. It is at a location where three tendons meet and connect to bone. The muscles include the sartorius, gracilis, and semitendinosus. There are also one or more bursae at this location. A bursa is a fluid-filled sac that decreases friction between bones and muscles.
When bursae become inflamed it is called

You will be instructed to rest the affected knee until the pain goes away. You may also be advised to ice your knee 3-4 times a day to decrease the inflammation.
You may be referred to physical therapy.
Nonsteroidal antiinflammatory drugs (NSAIDs) help with pain and inflammation. Your doctor will advise you which NSAID to take and how often.
You may also receive a steroid injection directly into your knee to relieve pain and inflammation.
