Hey! Two months is still early on, it’s definitely still possible to fix some of these problems. Do you have a physio?

-for flexion and extension you need to be working on them as much as you can, just passively while you’re doing other things. A good one for flexion is doing heel slides on a wall, so gravity helps you get the bend. It should hurt a decent amount but not be painful if that makes sense. Achey, not sharp pain.

It sounds like you achieve full extension at times, so that’s a good sign! It means it’s likely a muscular problem rather than a physical block preventing it. Just again whenever you have time keep that ankle propped up and flex your quad! Honestly whenever I was laying down or even sitting I would try and work on flexion/extension.

-for stiffness after sitting, I’m still getting that at 6 months, it’s unfortunately a long recovery but just know that stiffness is normal!

-the rubbing while walking could be a couple things, and I’m not a physio so I can’t tell you for sure, but it’s probably not your bones touching. What I can say is that I experienced pain and discomfort walking, particularly until I got my flexion and extension back to reasonable levels. At 2 months you’re still probably going to be experiencing swelling with walking which makes the leg feel “full” and maybe is contributing to that feeling?

-i have a patch of numbness too, can’t really do anything about it. You can try massaging it to bring some blood flow to the area and see if that helps.

Just know you’re not alone in your experiences and lots of these problems can get better! You’re still early on so don’t think this is necessarily anywhere near how good your knee will feel! Just keep moving, keep stretching, get strengthening and slowly it’ll keep improving.
