The meniscus is semilunar fibrocartilage (orange area) triangular cut.
Each knee has two menisci, a medial meniscus and a lateral meniscus.
They are "shock absorbers" of the knee: they have a role in the transmission and distribution constraints. They increase joint congruency and stabilization of the knee. They allow shock absorption and protection of cartilage.

At the top is the femur, the thigh bone. Downstairs there is the tibia, the leg bones. The bottom of the femur is rather round and the top of the tibia appears much flatter. The menisci are small blocks located between the two knee bones.

The hamstring muscle group consists of three muscles of the posterior region of the thigh:
the biceps femoris muscle (long head)
the semitendinosus muscle
the semimembranosus muscle.
They are mainly flexors and secondarily leg extensors of the thigh. When walking or running, they are also antagonists quadriceps, slowing the advance of the leg at the end of the step and preventing the brutal and full knee extension.
