Thanks MD. I did read somewhere on the net that women have a running and jumping style which engages the quadriceps more than the hamstrings and wider hip and it all adds up to an increased tendancy of knee injury.

I used to run a lot but be slack with weight training so I might be the type of person who would exacerbate this for themselves a bit.

I'll ask to be put on the isokinetic thingy. Thanks for the input - I was getting paranoid and it's comforting to know it could still be manageable just with weight training.
