Pes anserine bursitis

Pes anserine bursitis is the inflammation of the bursa located between the tibia and the tendons of the sartorius, gracilis, and semitendinosus muscles at the medial aspect of the knee. It is clinically significant as it can cause pain and tenderness, particularly in athletes and individuals with obesity or osteoarthritis, impacting mobility and quality of life. A key association is overuse or repetitive strain, which can lead to chronic pain and functional impairment if not addressed.
