Which acupuncture point is located in the hollows formed when the knee is flexed, below the patella and near the medial and lateral aspects of the patellar ligament?

• A. Bafeng
• B. Lanweixue
• C. Dannangxue
• D. Xiyan

Answer: (D)

Xiyan refers to the two points that sit in the hollows on either side of the patellar ligament when the knee is bent. These spots are exactly where the medial and lateral aspects of the patellar ligament form shallow depressions, so they’re commonly called the knee eyes. They’re a classic local point for knee issues like pain, swelling, or restricted movement. The description in the question matches these hollows precisely, which is why this pair is the best choice. The other names point to different locations (elsewhere on the leg or foot) and do not describe these knee hollows beside the patellar ligament.
