PES BURSITIS SERIES

Bursae can also protect other tendons as tissues glide over one another. The bursa is a small sac that cushions the bone from tendons that rub over the bone.

Bursitis of the knee occurs when constant friction on the bursa causes inflammation. Coexistent bursitis, tendinitis, arthritis, or internal derangement of the knee may confuse the clinical picture after trauma to the knee. Welcome to FYZICAL Windbers patient resource about Pes Anserine Bursitis of the Knee. The pain of pes anserine bursitis is constant and is characterized as aching it may interfere with sleep. Often, patients are unable to kneel or walk down stairs. Activity, especially that involving flexion and external rotation of the knee, makes the pain worse, whereas rest and heat provide some relief. Patients with pes anserine bursitis present with pain over the medial knee joint and increased pain on passive valgus and external rotation of the knee. The medial collateral ligament is crossed at its lower part by the tendons of the sartorius, gracilis, and semitendinosus muscles. This broad, flat, bandlike ligament runs from the medial condyle of the femur to the medial aspect of the shaft of the tibia, where it attaches just above the groove of the semimembranosus muscle it also attaches to the edge of the medial semilunar cartilage. With trauma to the medial knee, the medial collateral ligament is often involved, along with the pes anserine bursa. Rarely, the pes anserine bursa becomes infected. If inflammation of the pes anserine bursa becomes chronic, calcification may occur. The pes anserine bursa is susceptible to the development of inflammation from overuse, misuse, or direct trauma.

PES BURSITIS SERIES

This bursa may exist as a single bursal sac or, in some patients, as a multisegmented series of loculated sacs. The pes anserine bursa lies beneath the pes anserine tendon, which is the insertional tendon of the sartorius, gracilis, and semitendinous muscles on the medial side of the tibia. Bursitis (bur-SY-tis) is a painful condition that affects the small, fluid-filled sacs called bursae (bur-SEE) that cushion the bones, tendons and muscles near your joints.
