MRI

Fluid collection is deep to the sartorius, gracilis, and semitendinosus tendons related to pes anserine bursitis.

Moderate joint effusion is noted.

Cartilage fraying and loss associated with subchondral edematous changes are seen at the middle weight bearing of the medial femoral condyle.

Marginal osteophyte formation also is noted.

Patella chondromalacia as cartilage thinning associated with subchondral edema and cystic changes are seen at the mid to lateral facet joints of the patella.

Case Discussion

The pes anserinus refers to the webbed foot appearance of the conjoined tendons of the sartorius, gracilis and semitendinosus at their insertion onto the proximal medial tibia. The pes anserinus bursa is located deep to the pes anserinus tendons and superficial to the semimembranosus tendon and distal aspect of the medial collateral ligament at the posteromedial aspect of the knee.
