You have two kneecaps—one for each knee.

• Each knee has its own kneecap, also called the patella.
• So, in total, there are two kneecaps in your body.
• The kneecap is a small, flat bone that sits in front of the knee joint.
• Its main role is to protect the knee joint and help with smooth movement when you bend or straighten your leg.
• It also acts as a lever to improve the strength of your thigh muscles during activities like walking, running, or jumping.

If you have any concerns about your knees or experience pain, it’s a good idea to consult an orthopedic doctor who specializes in bones and joints.
