Knee Joint Basics

Knee Joint Basics

The point at which two or more bones are connected is called a joint. In all joints, the bones are kept from grinding against each other by lining called cartilage. Bones are joined to bones by strong, elastic bands of tissue called ligaments. Muscles are connected to bones by tough cords of tissue called tendons. Muscles pull on tendons to move joints. While muscles are not technically part of a joint, they’re important because strong muscles help support and protect joints.
