Abstract

Injuries cause a systemic neurohumoral and behavioral response of the body, aimed at restoring damaged tissues and correcting biomechanical disorders. However, in many cases, full-fledged repair is impossible – traumatic injury, inflammation that occurs against its background, and degenerative processes (fibrosis, neoangiogenesis, heterotopic ossification) lead to severe structural changes and a progressive decrease in functional ability. The most common complications of trauma include chronic post-traumatic pain and post-traumatic osteoarthritis (PTOA). These complications are interrelated – pain (accompanied by stiffness and dysfunction) that occurs in 10–50% of people who have suffered a joint injury may indicate the formation of early (pre-radiological) stages of PTOA. The development of typical structural changes in PTOA is observed 10–15 years after a knee injury (in >30% of patients). PTOA of large joints is more aggressive, often accompanied by synovitis, and requires arthroplasty on average 10–15 years earlier than primary osteoarthritis. Early diagnosis of PTOA is based on the analysis of the dynamics of clinical manifestations (primarily post-traumatic pain), visualization of early changes in the structure of the joint (magnetic resonance imaging), as well as the study of the level of biomarkers of inflammation and osteochondral destruction. As additional risk factors for PTOA, genetic features are considered that determine the chronicity of inflammation, pain, and impaired repair of cartilage and bone tissue.
