No, but I am writing to wish you well. Have you talked to Dr Gross? Is range of motion your sole concern? Have you tried taking time off, like just walking for at least a week?
Good luck.
(I don't have any issues tying my shoes. I am able to do deep squats and get up unaided, but not always. I tried to do what you describe, bring my knee to my chest. I can get decently close without using my hands. The leg lifts higher than 90 degrees. It is hard, though, because I don't have the flexibility in my hamstrings/back to get it that high. I can do pigeon pose, though. I can't straighten the leg once it is that high without it coming lower.
FWIW I feel like this recovery has been two steps forward one step back. I feel good, surge forward, test my limits, over reach, have to back off. For example, run 10k, enjoy success, feel beat up, have to wait a few weeks before doing it again. But progress is made: I can run a 10k distance, not racing, every other day now, but it took more than a year to do that after running that first one. I am not niggle free, especially not when I keep pushing.If I take a week or so off and don't push, just do things I can already do, I do feel normal.)
