An anatomical cap is a type of protective headgear that covers the PATELLA, or kneecap. It is typically made of a hard material such as plastic or metal and is designed to protect the knee from impact or injury. The PATELLA is a small, triangular bone located at the front of the knee joint and is essential for movement and stability. Anatomical caps are often used in sports such as football, basketball, and soccer to provide extra protection for the knee.
