isn't that more likely because historically have been far more games played on hard than carpet? and also by the fact that it's been so long since any of us saw matches on carpet, we wouldn't remember as many injuries in the first place.
but nevertheless, you might very well be right. it was just a thought.
no, not really, carpet has always been a historic surface
hard courts, less so. game started on grass, then clay.
tennis is a very injury inducing game, but generally, hard courts force the body into unnatural contortions moreso than other courts
