Semitendinosus insertion?

Explanation:
The semitendinosus attaches to the medial surface of the tibia, near the proximal end, as part of the pes anserinus with sartorius and gracilis. This placement on the inner aspect of the upper tibia is what lets the hamstring contribute to knee flexion and, when the knee is flexed, internal rotation of the leg. The other options don’t fit because the medial malleolus is at the ankle, the lateral surface of the tibia is on the outer side, and the ischial tuberosity is the muscle’s origin, not its insertion.
