PROGRESS! Doc cleared me for partial weight up to 80lbs now, single crutch/cane next week, then full weight bearing "as tolerated" the week after. That makes almost exactly 3 months on crutches. I've been shuffling around the house with a cane to get used to the idea - no pain, but my knee feels really weak, and after so long the idea of actually taking a step without the crutches is pretty intimidating. First PT appointment is next week - primary goal is just to get walking reasonably well again, then hopefully work up to some road rides and mellow mountain biking this summer if the doc will sign off.
