Boss had one of his knees done a couple of years ago, then continued to play rugby, till it happened again, then had the op to remove some more stuff form his knee, he decided to give up rugby and take up quad biking!!

Anyway his ops were successful at the time, had him walking out the hospital the same day, but he was in pain, however he was walking pain free within the week, but it only lasted a few months but may not have been helped by his activity.

So to sum up, don't let your wife play rugby or use a quad and she should be fine!! Good luck!
