knee replacements
I had bilateral total knee replacements on 7/2/08 (yep, both knees). Stationary bike riding is one of the 1st rehab exercises I started (after all the straight leg raises). I am VERY happy with my new knees. Yes, it was a slow & difficult recovey, but I did everything I was told to do (likely for the 1st time in my life), and I rode my bike several miles for the 1st time at 7 months in recovery. I likely could have begun before that, but I wanted to be totally comfortable with my balance and range of motion in both legs before I started. That was a very happy day for me!
