We have had other slow to gain ROM members, here is a list of how their ROM increased over time.
Since you are past 90 degrees, sounds like time is what your knee needs.

26 weeks (where I am today): 120!!!
It has now been 26 weeks and all I do is ADL.
I did it! My goal of 120! No "pushing through pain", no PT after the first 3 visits, and most importantly to me: No MUA! My surgeon who said I would never get beyond 85 ROM without pushing through pain was wrong, wrong, wrong. I'm excited to see if it gets even better.
