Im not in your body/knee but I think if your problem is so localized, how could it be CRPS? If you google or talk to people that truley do have CRPS it is pretty wide spread and usually accompanies a number of deformities, color changes, and other abnormalities, none of which you seem to have (to my limited knowledge of your situation).
Honestly, Im not in your body obviously, only you know how your knee felt pre injury, after the intial injury, how much time you gave it in physio before having your first surgery, then second surgery. My personal opinion, coming from a pure laymen/ fellow struggling patient and Im going on a hunch here, is that either 1)you didnt give physio and healing enough of a chance before your initial surgery and you might have had an unnecessary surgery to begin with 2)the lateral release was unnecessary and caused more problems 3) the TTT was unnecessary and caused even more problems.
try to find a PF specialist close to you or an OS that will check for all abnormalities from hip to foot. The good ole CT rotational study as they call it. The one that addressess the femoral and tibial torsion, TT-TG offset, trochlear groove depth. A skilled surgeon that can do all of the proper testing to see if things are in the right place.
If you need to use a wheel chair for the time being, I see no shame in that and youre a young man and if that is what you feel you need than use it.
Without bandying too much, I regret nothing. My decision-making process has been driven by the very pragmatic goal of getting back into a cockpit. From the outset, I said I'd do whatever it took to give me the best chance of making it back up to speed, even if it meant taking some risks and making some sacrifices. So I'm paying a price.... so what? It was a good bet. I guess that's all I really have to say about that. I'd do it all again, hell, maybe I'm about to. Worth it. When they talk about me someday, they aren't gonna say I was too scared to act. Too dumb to know better, maybe, but I made my choices and I can live with that.
