Hi, please don't despair, you are not alone. This is a devastating injury that really does take a long time to recover from. I am just over 3 months now from a comminuted fracture and I still have trouble sleeping. Are you taking any pain Meds? I was worried that I shouldn't still need pain relief but I do. Do you sleep with a pillow between your knees? The most useful bit of kit that I have found is a Cyro Cuff, it cost about £100, gives you about 6 hours cold therapy and really is a life saver. I too have good rom and can do pt but I feel my knee has a ball and chain attached to it!! I massage my knee constantly with oil and this helps. Are you in U.K.? Good luck and be patient.
