The pain when you snap a cruciate is described as being like getting shot in the knee. And a repaired cruciate is never as robust as an undamaged one. Even as late as the mid eighties a ruptured cruciate was considered a career ending injury. Better surgical techniques developed in the US now mean that this is no longer the case but as I said....it isn't as strong as an uninjured one and so the risk of reoccurrence is consequently higher.
The only person qualified to make that statement would be someone who had ruptured the cruciate and been shot in the knee. Even then the experience is subjective.
