I broke my ankle almost 4 years ago now. I basically shattered my tibia and my fibula was in pieces. I now have plates and screws that will always be there. I broke my ankle in August and had my first surgery the next day. I started riding with my cast on (my doctor hates me) two weeks after I broke my leg. I was only walking. I was in my cast for 6 weeks, then I was put into a walking cast but I was NOT allowed to put weight on my leg until the middle of December. I did start seeing a physical therapist when I got the walking cast, and that really helped. I was riding, but riding without stirrups which helped to build my leg muscles back up but was not straining the joint. The first week I was able to walk in December I slipped on the ice and torn a tendon. So I was back to no weight for the next month. Then I had a second surgery. Another month with no weight on my leg. SO total of 7 months. I didn't have enough money to continue with the physical therapy for my leg which was really too bad. It is well worth the money and really helps. Be honest with them and tell them you can't afford it for long and the one I went to was great about working out a plan and giving me exercises to work towards and things I could do even when I couldn't see her anymore.
4 years later I can still ride, but my ankle is not 100% to where it was, but I can get my ankle down and still ride well. I cannot run, it puts too much force on my joint and it swells. My physical therapist did NOT want me to wear a brace because they said it will get stronger if don't. I had to go back to my surgeon this past year because I was getting stiff, and I started going back to the physical therapist.
My ankle is never going to be 100%. I had a horrible break, so I hope yours was not as bad as mine. It doesn't inhibit my riding though. I am really stiff and sore afterwards, and sometimes I ice it if I had an intense ride. There are just some things that I know I can't do anymore, like run (but I hated that anyway).
Sorry for the novel
