What is the function of the tibial tuberosity?

Expert Solution
Step 1

Tibia, also called sin bone, is the lower leg's larger and stronger bone. The tibial tuberosity, a major bony ridge, lies below the condyles on the tibia's anterior surface. It forms the terminal part of the structure, acting as a lever to extend the knee joint and prevent knee collapse when the foot strikes the ground. Tibial tuberosity serves as an attachment point for the patella through the patellar ligament.
