Viral arthritis

Infectious arthritis - viral

Viral arthritis is swelling and irritation (inflammation) of a joint caused by a viral infection.

The structure of a joint

Joints, particularly hinge joints like the elbow and the knee, are complex structures made up of bone, muscles, synovium, cartilage, and ligaments that are designed to bear weight and move the body through space. The knee consists of the femur (thigh bone) above, and the tibia (shin bone) and fibula below. The kneecap (patella) glides through a shallow groove on the front part of the lower thigh bone. Ligaments and tendons connect the three bones of the knee, which are contained in the joint capsule (synovium) and are cushioned by cartilage.

Shoulder joint inflammation

An inflammation of the shoulder joint can cause pain and restricted joint movement.
