In pes anserine bursitis, where is tenderness most commonly found?

• A. Lateral femoral condyle
• B. Medial tibia just inferior to the proximal medial tibial plateau
• C. Patellar tendon insertion
• D. Medial collateral ligament insertion

Answer: (C)

Tenderness from pes anserine bursitis localizes to the medial proximal tibia where the pes anserinus bursa sits between the tibia and the tendons of sartorius, gracilis, and semitendinosus. When this bursa becomes inflamed from overuse or valgus stress, palpation over that medial tibial area a few centimeters below the knee joint line reproduces tenderness. The other sites correspond to different knee structures (patellar tendon insertion at the tibial tubercle, MCL insertion higher on the medial knee, or the lateral femoral condyle), which are not where the pes anserine bursa lies.
