People do heal at different paces. I haven't had the knee job yet but I am sure it is coming with all the torture I have put mine through. After the doc put my arm back together and my ribs healed from the get off in Aug ’09, it was two months before I could squeeze the clutch and another month before my first ride on a my wife’s little Ninja. I couldn’t hold myself up with the left arm though as the darn Triceps ware still too puny.
After hitting the deer in Aug ’11, it was a whole month before I could ride again after my sternum fracture. And that was still tough as any pressure caused by moving the arms to and fro cause a slight discomfort. (Ok, maybe ‘slight’ is an understatement. It hurt like hell but I couldn’t stay off and needed the wind therapy to distress).
K^2, I hope your time off is spent well and that your recovery is a quick one. BTW, don’t pinch your PT’s butt, evidently that is a no-no these days…
