How long does it take for your mobility to go back to normal?

I got Precice 2.2 done in early March and decided to do the whole 3 inches. It has been 2 months since I finished lengthening but hamstrings, quads, and most importantly, hips are still extremely tight. Not to mention I'm still using 1 crutch and won't be off them completely until early September.

Just worried my mobility will never be back to what it was pre-surgery. It's crazy because I used to be able to touch past my toes and now my hands get to about 5 inches from my toes.
