The term “pes anserine” is Latin for goose’s foot, and describes the appearance of three tendons that converge and insert on the inner portion of your knee. The pes anserine bursa is a fluid-filled, friction-reducing cushion, sandwiched between these tendons and your leg bone.

Injuries or irritation can cause the lining of the bursa to produce too much fluid, resulting in painful swelling. Patients with knee osteoarthritis are likely to have chronic irritation of the pes anserine bursa. The condition is more common in overweight patients, diabetics, and females. Runners and athletes in sports that require rapid side-to-side movements (i.e. football, soccer, tennis, etc.) are more likely suffer from the condition. Swimmers who do the breast stroke commonly suffer from pes anserine bursitis.
Symptoms include pain on the inner side of your knee, just below the joint. Your pain is probably worse when you stand up or walk stairs. Discomfort increases during activities that require side-to-side movements (i.e. tennis, dancing). Be sure to tell your doctor if you notice clicking, popping, or locking of your knee, excessive thirst, excessive urination, fever, or pain & swelling in your calf.

In addition to the treatment provided by our office, you may find relief by applying home ice or ice massage for 8-10 minutes. Having flat feet places additional stress on the inside of your knee, so patients with fallen arches will benefit from arch supports or orthotics. Overweight patients will benefit from a diet and exercise program.
