The Quinx procedure is newly developed, so it definitely wasn't around when Arima was young.

In terms of hybrid stuff, I recall that Shinohara mentions that hybridization was previously discussed but banned due to being considered unethical. So Dr. Kanou is the first one known to have actually done it, and his comments about Kaneki suggest that was his first success.

So right now, we really don't know whether Arima just is that good or was modified. His past is kind of a mystery other than, like Juuzou, being made an Investigator by the chairman himself.
