Pes anserine bursitis is the irritation of the bursa on the inside of the tibia, near the knee joint. This bony area constitutes an insertion zone for three muscles: the sartorius, the gracilis and the semitendinosus.
Sports and activities that require these muscles to be repeatedly contracted or stretched while running, hiking, or any other extended activity can cause irritation of the bursa and sometimes inflammation. Pes anserine bursitis may be associated with an injury to the tendons in that area. It can occur as a result of trauma directly to the knee. Muscle imbalance in the hip or knee may also contribute to the onset of symptoms.
Pes anserine bursitis can produce, but is not limited to pain on the inside of the knee, localized edema due to swelling of the bursa and reduced mobility in the knee. Symptoms are usually worse while running, walking on a sloping surface and climbing stairs.
Treatment of hamstring injuries consists of Class IV Laser Therapy, management of any biomechanics stresses in the area and exercise rehabilitation to address any weaknesses that can be putting undue stress on the area.
