Post-Traumatic Arthritis Definition

Post-traumatic arthritis may occur if the cartilage in a joint is damaged during an injury. It may also occur if the trauma to the joint has weakened the tendons and ligaments, which may destabilize the joint and render it more prone to developing arthritis.

The majority of post-traumatic arthritis cases are considered types of osteoarthritis. However, the cartilage degeneration that occurs in post-traumatic arthritis results from sudden injury and not gradual wear and tear as is the case for osteoarthritis.
