It looks like the biggest problem will be building the strength back up in my leg after no use for so many months. My calf muscles in that leg are already atrophied and only going to get worse.
Right before you start working on the calf, it's going to look like an overweight elementary school teachers tricep while she's writing on the chalk board (or white board for the youthful). Just be prepared for it.
Oh, and work the limp out of your step as soon as you can. You may have to learn that again. The sooner the better for your knee, hip and back.
