Where is pain most often located in pes anserine bursitis?

• A. Inner aspect of the knee near the medial tibiofemoral joint
• B. Outer kneecap region
• C. Calf muscle bulk
• D. Anterior ankle

Answer: (A)

Pain from pes anserine bursitis is felt on the medial (inner) side of the knee, right where the pes anserinus inserts on the proximal medial tibia, just below the medial tibiofemoral joint. The bursa lies beneath the tendons of sartorius, gracilis, and semitendinosus, so inflammation causes localized tenderness and aching in this medial knee area. Clinically, patients often report medial knee pain that worsens with activities that bend and load the knee, such as stairs or squats, aligning with this medial tibial insertion region. This location distinguishes it from lateral knee problems, calf or ankle complaints, which would present elsewhere.
