Thanks everyone, this is a great community ! I have slight psoriasis. When doctor replaces the my knee (Feb 21), does he need to do anything different if the knee has Psoriatic Arthritis Vs Osteoarthritis ? I dont have psoriasis on the left knee to be replaced. Only slight psoriasis I have is on my right leg. Can you help me give details for differnt in surgery steps or process for Psoriatic arthritis Vs Osteothritic knee replacement ? And do I need to tell the surgeon anything ?
