Also, since PT isn’t helping, maybe consider stopping that. Sometimes the more PT we do, the more we maintain upset tissues. Maybe yours need to time to calm down.
I'd echo this. I also have a Patellofemoral PKR and my recovery has been quite good so far. However, every time I started doing some strengthening exercise (because I though it'd help me recover faster), I ended up upsetting my surgical knee and was forced to stop doing it a few days later. For me, just walking and biking worked really well.
