Talonavicular fusion and running again?

I will say u should be able to run and do mountain biking but u may not be able to do as much as before. I am 19. I broke my navicular bone playing football in college. I got the surgery, took 2 screws and a stabilizer. 6 months later i began training for boxing. I am on my way to compete in the Golden Gloves (regional championship). From there will be nationals and international championships. I have slight pain (1 month after final exam) but its slowly going away as i strengthen the joint. I can run and jump pretty well. Not anywhere what i could before, no. But, the issues are minimal and usually temporary.... well other than the weather pains. U may be stuck with those but they are not that bad at all. Just annoying. So no, u may not be completely pain free but if done properly u will be WAY better off. As long as you FOLLOW THE DOCTORS INSTRUCTIONS. Even to the smallest detail. Doc knows, we just recover.

I am 21, and was diagnosed with Pauciarticular Juvenile Rheumatoid Arthritis when I was 4 years old. I’ve just been told by my rheumatologist that I now have full blown RA in my talonavicular joint. In the past year there has been about 70% degeneration. I was recommended the talonavicular arthrodesis, but am very skeptical because I was told running was going to be almost impossible for me. Can anyone provide some insight on how their living conditions have changed, and if they can run without pain for long periods of time. Thank you.
