I have done years of PT it's as good as it's gonna get. It's my left leg and The actual ROM is about 45-50 degrees. I have tried to ride a bike - not possible WO changing something.
Thanks for the replies...
Well, then it looks like you will have to go with shorter crank arms. What is the length of the crank arms on your bike now? Do you have your seat adjusted to the proper height(down leg almost straight)?
