in the early to mid seventies I suffered from ulceritive colitis. I was treated with prednisone and salazopyrin. I am npt sure how long I was on prednisone as no doage records are available. I do know that I was on salazopyrin steadily for about one and a half years or longer. I have been suffering from arthritis for the past twenty years (knees)and am slated for total knee replacements.

what I would like to know is can I make a case that my arthritis could have been caused by using prednisone and/or salazopyrin. No other member of my family has suffered from osteo arthritis.
