May speak with surgeon as it’s critical to address possible scaring before it’s too late to fix it by an MUA. Recommended before 12 weeks to be most effective.

Your joint is not a functional joint at this point. I did PT 3x/wk, taking 5mg oxycodone before, as the therapists worked hard to get me to bend or flatten- to no avail. Had the manipulation under anesthesia and gained almost 30*, and now can flatten my leg.
Had to really make noise and be my own advocate. Your nerve issue slowed you down and you probably formed scar tissue around that joint ( I do not mean scars on the incision either). Arthrofibrotic bands of scarring tissue.
