First month following knee replacement.  I am able to do full forward and reverse spins on the seated recumbent at the PT's therapy center.  I'm getting a bit discouraged because I have plateaued at 95% flexion and can't seem to get more.  PT says it will come with time.  Rotation on my bike in the basement is difficult.  I got one reverse rotation yesterday and it was a killer.  I need to be sure to not over do in order to not set back my progress.  I will try to be more patient but it's difficult.  More updates later.
