Traumatic arthritis is a form of arthritis that is caused from blunt, penetrating, or repeated trauma to a joint. Damage to the articular cartilage can occur when too much pressure is exerted on a joint, causing the cartilage to rip or break into small pieces that become lodged in the joint. Holes in the cartilage develop scar tissue that can reduce the ability of the joint to move freely. The joint can be made weak and inflamed, which causes the pain associated with arthritis.
