Stumbled on this thread today and I just wanted to say thank you to all that participated. I'm 43 years old and scheduled for TKR on December 5th. My cycling has been cut from 200 miles a week to about 40 a week. Those 40 are very painful, so its time for the surgery. There are so many opinions on PT, some say no pain no gain, other say PT shouldn't be painful. Not sure what to think, the more I read the more confused I seem to be. My current flexion is 90-95 and I've been riding shortened cranks 155mm for years. I'm hopeful and it's my goal to be able to ride "standard" cranks post surgery.
The success stories in this thread helped my frame of mind today. Much appreciated.
