Which acupuncture point is located near the medial aspect of the knee and can be palpated as a tender depression in relation to the vastus medialis?

• A. Baichongwo
• B. Lanweixue
• C. Heding
• D. Dannangxue

Answer: (B)

Locating certain acupuncture points relies on feeling for a tender depression in the soft tissue near a joint. On the medial side of the knee, in line with the vastus medialis, there is a tender depression that corresponds to Lanweixue. This point is identified specifically by that tenderness and its position near the inner knee, which matches the description in the question. The other named points are not characterized by this exact medial-knee tenderness in relation to the vastus medialis, so they don’t fit as well.
