Arthritis of the knee can make taking a step painful. Swelling, pain, and stiffness in the joint are just some of the symptoms that can occur when a person has this condition.
The knee joint is a hinge joint, named for its movement that's similar to the opening and closing of a door.
The joint consists of three main bones. The areas where each of these bones meet are covered in a protective material called cartilage. Additional pieces of cartilage known as the meniscus further support the knee.
All of these protective pieces of cartilage keep the bones in the knee from rubbing together, which can be very painful.
