I don't know if the injury rates are higher for pitchers who have had TJS, to be honest. But I do know that pitchers who have had TJS tend to be harder hit by elbow injuries than other pitchers, and I also know that pitchers in general are huge injury risks, so I don't think it's going out on a limb to say that one of JZimm and Stras is going to miss significant time on the DL in the future.
