KD-10 is located at the medial end of the popliteal crease between which tendons?

• A. Semitendinosus and Semimembranosus
• B. Biceps Femoris and Semimembranosus
• C. Semitendinosus and Biceps Femoris
• D. Popliteal Artery and Vein

Answer: (B)

KD-10 sits in the popliteal fossa at the medial end of the popliteal crease, in the groove between the hamstring tendons on the medial side. The two tendons there are the semitendinosus and the semimembranosus. This spot aligns with the surface landmark described for KD-10, because those tendons form the medial boundary of the popliteal region and create a distinct space just behind the knee where the point is palpated. The biceps femoris tendon lies on the lateral side, so the space between it and the semimembranosus would be away from the medial end. The popliteal vessels are deeper in the fossa and not the superficial landmark used for this point.
