Saw the doc for my two year knee replacement checkup last week and got good and bad news.

The good is that the implant is solid and doing exactly what it's supposed to do. It is growing into the bones perfectly and shows no signs of distress.

The bad news is since my knee is so full of scar tissue from the five previous surgeries, my mobility is permanently compromised (you can still gain some increased range of motion in the first 18 months). I'm at 104 degrees of flexion and 5 degrees of extension; what that means is at 5 degrees extension I have a slightly impaired gait (I limp often since I can't straighten my leg all the way), and bike riding requires about 117 degrees of flexion so when I attempt it I end up tearing scar tissue loose. All in all it's better than before the surgery, but I sure wish I'd had a better result.

Thanks to you gals who were so encouraging as I walked this new path, much appreciated.
