I admire your enthusiasm. What baseballhs is saying is that there is now a huge oversupply of players, due to covid and the reduced draft. Why would a coach take a chance on someone who has been injured and hasn't played for 3 years, when there are covid holdovers and juco players and regular transfers available, who have been playing at current schools or in collegiate leagues? To do this after surgery, you'll need a carefully thought-out recruiting plan, one that includes levels below D1.
