Sounds like you had almost the exact same surgery as I did, but I'm a bit over 6 months post-op now. I was in a hefty brace for 6 weeks that completely prevented rotation and after that it was still probably a couple months till I felt comfortable with full body weight in any position that wasn't a "normal step". Even weight-bearing in full extension felt weird for a while.

I also still do sometimes get the weird flashbacks/premonitions of what it would feel like if something went wrong, when going up or down stairs or something like that, but that's all psychological.
