Hello, As per you history, what I see is, it s a old injury. and also a complete rehab plan will still make you have same symptoms at any point of stage in life. As body once gets injured will always be on a non reversible side. initial ages there are healing process which allows new tissues to come and become better. but in certain areas the injury is irreversible and also at the later stages of life it shows symptoms of pain and inflammation. There will be a lot a muscle weakness too. so to avoid or reduce the chances of recurrence of the pain symptoms you need to constantly keep doing exercises to improve to range and strength. In many cases arthritis is not a one day or one month process. it s always a long term building process of ageing process of the joints and muscles. Thus, a regular exercise to help improve the strength and agility is always helpful. Take care. Hope I have answered your question. Let me know if I can assist you further.
