How much torque (N m) does a golf swing put on the average person/Tiger’s knee? What can I compare this to?

As is obvious to anyone who has seen Tiger swing a club, he puts a tremendous amount of torque on the knee he is getting surgery on. I am wondering if there are exact measurements as to how much torque people, particularly Tiger, put on their knee during a golf swing. As I am relatively unfamiliar with physics, I would also appreciate a comparison of that measurement to something understandable.

Interesting, I was pretty curious about this question. I bet someone out there has done some work on this sort of thing.

I did find this… http://www.jssm.org/vol4/n4/17/v4n4-17pdf.pdf

This paper only gives torque data for the club, but I think you could relate it the torque in the knee. The torque in the knee is probably somewhere within the ball park of the torque of the club, perhaps 5 N*m. This would be like hanging a bag of 5 apples off the end of a yardstick duct-taped to your knee. This is the Maximum torque, which is only applied for a fraction of a second, but if you do it a couple million times… ??
