Honestly there isn’t a lot I can think of for the actual rehab side, for the first months I was super diligent with all my exercises, stretches, pool walking, self massage, and reported back to my physio as I made progressions based on feel.
The day I was cleared for 100% weight bearing, I took my bike outside for a rip, just pull the bandaid off.
Only regret I really have is letting myself go a bit too much as far as the dietary habits go, as I had shed 50+ lbs before my accident and put every pound back on.
That said the extra food likely helped heal the bone and rehab muscles, but it made getting back to normal activity levels harder, and I had less motivation to get out and move.
In the end it all came back off though, I jsut had to fall back in love with the bike.
