The Leg lift hurt too much for me to really get to grips with, so I didn't and left it alone. As I said, on the leg extension set up, I can now lift 10kg.
Buy around six 300gm cottage cheese cartons. The contents will do you good and the empty cartons are perfect for your Aircast. When you freeze them, carefully so you won't have any spills, put them in the freezer and a bit of physics here, without a lid. That way no split cartons.
Once the water was cooled, I reckoned I got through around four blocks a day to begin with, Far easier than fiddly ice cubes although I used up the ones I'd frozen by just putting the whole bags of them into the kit.
I was ready to rent a Game Ready, but the Aircast came from the hospital and it seemed quite adequate so I kept with it. Saved a bob or two.
As far as the leg lift was concerned, I used to hoist myself up onto the kitchen table and swing my legs. The free movement let me ''lift'' the leg as far as possible, without actually having to do any actual work with the quads.
Pain. I didn't have any as such. I have a very high pain threshold, but found if I took my codeine phosphate and paracetamol as prescribed, then I just had discomfort. Yes, extreme at first but no actual pain. The worst time was in bed. I just did NOT know where to put the leg for many many nights and 3am ish saw me up for weeks on end, but it does go. Truly it does. I gave up on the codeine approx [I've actually forgotten when] three weeks. Paracetamol after six weeks, again, forgotten actual date.
I started gentle physio with a lady who has over seen ''the knee'' for years, around a week after the op. I still see her once a week, sometimes in the gym and sometimes on her treatment table.
I didn't believe that this caboodle could take over a year to settle, but I certainly believe it now and I'm one who has almost sailed through all the stages.
Don't worry, ask away and HUGE amounts of good luck to you.
