Here is a study published from 2007, so I don't know how good the data is.

It showed favourable results in general, but they also conclude that there isn't enough data. It's also worth mentioning that all of the sports studied were solitary games that didn't involve getting hit by another full grown man at 35+ km/h. They used competitors from sports like table tennis, skiing, archery, rafting, running, diving, etc... The athlete who competed in karate was probably the most violent sport used in the study and that athlete did in fact have to quit due to not being able to make fast turns without great pain.

Not sure how relevant any of the data is. Probably not very.

Here is another one from Mayo Clinic.
