@billjan1950, @jnoronha, It does appear that you two have similar quagmires.........recovering from TKR procedures within the time frame you had been expecting, and without the pain you hadn't been expecting. My experience, unlike yours or anyone else's is also different. I have neighbors on both sides recovering from a partial and a total procedure. I don't understand the partial concept but then I didn't choose it. I did hear him say he was going to have another partial on the other knee. Maybe two partials make a whole. "Enough of this for today.....Chris"

The situations that we are dealing with are varied and somewhat unpredictable unless everything is 100% the same. And if that were true (100%) you wouldn't need the surgery and I wouldn't be writing this to try to show you comfort and provide support. What I can do is refer you to a Discussion Post that I wrote a bit ago. If you have a few extra minutes read some of the posts by others. Many have struggled with implementing a rehab program that should have led them to functionality without discomfort within a year.

There is no magic exercise or cream or any other form of technology that will make a difference. You can eat right, exercise correctly, sleep well, and keep a heck of a good attitude and you still may run into difficulties.

This is the time to make doubly sure that you asked the right questions of the right person and that there were no misunderstandings or forgotten messages. Because you know more now, you probably can do a better job of describing the sensations you are having and responding to the medical questions you may be asked. Double-check your understanding of verbal suggestions or ask for it in writing.

And finally, just do it exactly the way your clinician says to do it. And then....when it starts to feel better, don't push it. Don't try to have more "bend" than anyone else. Just pat yourself on the back and drop a note to Connect. I am here for you and anxious to be a part of your journey.
May you be free of suffering and the causes of suffering.
Chris
