Which bone is the weight-bearing bone of the lower leg?

Explanation:
The weight-bearing bone of the lower leg is the tibia. It is the larger, medial bone that directly transmits most of the body's weight from the femur down to the ankle, making it the primary load-bearer in standing and walking. The fibula runs along the outside of the leg and mainly provides muscle attachment and stability at the ankle, carrying only a small portion of the load. The patella sits in front of the knee and enhances the quadriceps’ leverage rather than bearing weight itself, while the calcaneus is a bone in the foot (the heel), not in the lower leg.
