Which muscle inserts on the posterior aspect of the medial tibial condyle?

Explanation:
The distal attachment described is a hallmark of the semimembranosus. This hamstring muscle has a broad tendon that inserts on the posteromedial aspect of the medial tibial condyle, and it also sends expansions to the posterior knee capsule and medial meniscus. This placement is distinct from the others: semitendinosus attaches to the upper medial tibia as part of the pes anserinus; gastrocnemius inserts on the calcaneus; and biceps femoris inserts on the fibular head. So the posteromedial tibial condyle insertion points to semimembranosus.
