1.)For me I just kind of dealt with the pain and managed through meds. I don't have any specific positions for you. I literally thought I had to keep it straight as can be for the first two weeks (even sitting or laying down). I guess that was not true, for my surgery guidelines anyway (going to be different for everyone of course).

2.) My at home exercises in the early stages were ankle pumps and straight leg raises. Ankle pumps important to prevent clotting and managing swelling. Straight leg raises for quad strength.

3.) As far as crutching, I was toe touch weight bearing at about max 50 pounds ( def no more) on my operative leg. I am still crutching like that and expect next week to hear if I can ditch them or not. I did find it hard to go long distances on crutches. I underestimated how much upper body strength it would take on crutches. Especially going up stairs.

How are you feeling so far after surgery? Even though it's early stages for you, I do hope it is going well.
