Hello, As post-traumatic arthritis should have a benefit of the medication prescribed but what sort of injury you had and what post-trauma training is provided is more important. Usually, joints go into inflammation due to joint receptors to aggravate and lead to pain symptoms. If you talking about your knee here, then you need to take the talk work behind your knee aggressively before going to any kind of risking the joint. Balance board training and multi-angle athletic training approach have to be made to avoid having inflammation of the traumatic joint. Also, you need to focus on the adjacent joints - both distal and proximal for the balancing. Which can also help you improve the overall training of the muscular system. If you do then you should recover in 4-6 weeks of time. Hope I have answered your query. Let me know if I can assist you further. Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
