Knee

Babies are born without knee caps. They don't appear until the child reaches 2-6 years of age.

The kneecaps of children are made of cartilage until the age of three years when it ultimately starts to turn into bones.

There are four major bones in the knee: the femur, tibia, fibula and patella (kneecap).


On September 30, 1987, at the Hospital of the University of Pennsylvania, 32-year-old Susan Lazarchick had the world’s first successful transplant of the human body’s most complex joint — the knee.

The complex operation was done to save the leg of Ms Lazarchick who had developed a potentially malignant tumor on her knee. The donor was an 18-year-old man who had died in a motorcycle accident a week before the transplant operation.

Bees do have knees but not kneecaps. Originally, in the 18th century, the phrase "bee’s knees" was used to refer to something very small. It came to signify excellence around 1920.

The knobbles on our knees are all different and it has been suggested they could replace fingerprints.
