I am only 23 yr old male (6'4" 270lbs) and feel stiffness in my lower back and knees (left knee has had ACL/MCL reconstruction and Meniscus surgery). I am worried that it is Osteoarthritis will over take me in the next decade and I fear how I am going to manage it. It is causing depression and uncertainty in my life. Every one around me is noticing that I don't have the same charisma I once did Any advice or ideas? Is this a manageable disease? Can I still live an active life style? Thank you in advance
