In light of this accomplishment, I am declaring myself healed. In an earlier post, I mentioned that I was giving myself until 18 months to finish healing since I was not completely happy with my progress. I feel certain that my unhappiness is related to the IT band problem that I must have been developing at that time and which made itself known a few weeks later as it insidiously progressed.
I will still have to continue my strengthening exercises and stretches, and I still hope to putter in my yard with a shovel someday, but these new knees are giving me a continued new lease on life.
