Never bought into the "must squat to grow" theory. This is coming from a guy who really loves the squat, too. To be honest, I found my upper body growth lags behind when tasked with recovering from intense leg/squat workouts and while not being assisted with anabolics. And I know plenty of guys with huge upper bodies that don't do much when it come to legs.
Work around your situation the best you can and see how it goes.
