Hi everyone I have diagnosed PSA in my feet/tendons. I had knee surgery (meniscus) repair last June and I think PSA has attacked my knees but my Ortho says it’s osteoarthritis not PSA. I won’t see Rheumy until May. Is it possible that in a 8 months both of my knees end up bone on bone from osteoarthritis? Had previous MRI knees appeared fine …just meniscus tear. Ortho started me on 4 Supratz injections which Ive done however my knees still kilI and I shuffle when I walk and when standing the pain is out of this world. Im 48 going on 98….Im annoyed at this.
