Distal femur orif, 9 months out have newish (last 3 months) knee pain in both knees

I've got a plate in the left femur from a motorcycle crash. Have been consistently doing pt. Dealing with what i assume is normal compensation injuries, have strained both groins, some hip stuff in the left hip but also have new knee pain (for the first time ever) in the right knee thats pretty much the same as the left knee. My left leg is at 50% strength of my right leg and my PT is telling me that he thinks we should be closer to 70%. I'm a previous powerlifter and am doing plently (maybe i need to be doing more???) in the gym. I can leg press 400 with the right leg and 200 with the left leg. However my knees hurt like a mother in that midrange 90-120ish degree range. Bulgarians suck, lunges suck, and it seems like it hasnt improved in the last 8 weeks (40% of the good leg to 50% of the good leg). Anyone deal with knee pain that limits their quad work (what my PT says I need to really be hammering on)? I need some reassurance and whats worked for people here.

Not looking for people to tell me that they still have pain and they are permanently messed up. That's not going to help my headspace right now. Looking for inspiration and what has worked for folks.
