causes of baker's cyst in knee
A Baker's cyst is swelling caused by fluid from the knee joint protruding to the back of the knee. Baker's cysts are common and can be caused by virtually any cause of joint swelling . A Baker's cyst may not cause symptoms or be associated with knee pain and/or tightness behind the knee, especially when the knee is extended or fully flexed. Baker's cysts can rupture and become complicated by spread of fluid down the leg between the muscles of the calf (dissection).
