Hope you're feeling ok x
I had tto plus mpfl reconstruction and I can tell you that even now almost 4 months post op I'm at times in tears due to the pain. I was never braced, only put in a cast for two weeks and was non weight bearing for approx 6 weeks,thereafter it was full weight bearing on both crutches and now I'm down to one crutch, my pain is intense at times, I frequent a & e almost weekly due to pain.
As for range of movement, take it easy, do little lots and never overdo, don't push your body too far end always ice afterwards, I've from day one of physio always taken my meds half hour before and iced afterward it's helped greatly, I now have a 115 degree bend and can do afull but painful revolution on a stationary bike. Don't expect things to get better in days, you've had major surgery. It's both physically and mentally demanding but you'll get there :-) just takes a wee bit time x ice, meds and tissues for when the tears come are gonna be your best friends for the next few months x
Take care and don't stress too much
Oh I know the popping you mean!! Try sitting at the edge of a sofa and using your good leg and placing it in front of your operated leg and push back with it, it helps get a better bend. Mine used to pop put I persisted with that type of bending plus standing holding a kitchen counter or wall and doing a standing leg curl! That's when I felt the pop sensation most but it's gone now :-D
I'm away back to sleep, hate the pain!!! I feel it's never ending!
