Post-traumatic arthritis males. The process of post-traumatic arthritis can be divided into three phases: immediate, acute, and chronic. This phase usually begins a few seconds after the injury; it is characterized by cell necrosis, collagen rupture, swelling of the cartilage, hemarthrosis, and the loss of glycosaminoglycans (GAGs). In this phase, acute post-traumatic arthrosis emerges. Matrix degradation, leukocyte infiltration, inflammatory mediators, deficient lubricants, and apoptosis can occur. Typically, the acute phase comes hours after the injury. The chronic phase occurs months or years after the trauma. Typical symptoms are joint pain and dysfunction. Post-traumatic arthritis is diagnosed with the help of a patient's
