Core Tip
Core Tip: Post-traumatic osteoarthritis (PTOA) is a secondary osteoarthritis that follows a joint injury. The knee is the most frequently affected joint, and the extent of injury ranges from simple to complex. PTOA is characterized by joint pain, swelling, and restricted movement. It is diagnosed beyond stage 2 of the Kellgren-Lawrence grading system, as evidenced by an X-ray. The disease begins after the joint injury, which further progresses due to complex biochemical interactions of cytokines, oxidative stress markers, enzymes, and collagen breakdown products. These markers can help us in a multidisciplinary approach thus emphasizing early intervention, biomarker-guided therapies, and mechanical stabilization thus, improving patient outcomes.
