A baby is born without a fully developed kneecap (patella). Instead, infants have a cartilage structure in place of the kneecap, which gradually ossifies into bone as they grow older. This cartilage allows for flexibility and movement during early development and helps accommodate the growth of the legs. Over time, the cartilage transforms into bone, typically around the ages of 3 to 6 years.
