@rjudith....are you out of the immobilizer? If so, I suggest spending every idle moment ambulating and exercising. I found that by sitting on a counter top or something that would allow my leg to dangle and allow gravity to work. You just have to overcome the atrophy and get the quads firing again. When you think you have done enough, do some more. Are you set up with a challenging home exercise program?
Saw OS Thursday & I was given a choice of immobilizer brace, crutch or cane. I do not have a crutch and only have the "Hurricane" which I saw on TV and I do not feel too sturdy but have a PT session/ maybe evaluation today. He refused to discuss another brace. For the last month I have had a have exercise program from PT = 3X per day every day - now not challenging but I have done it religiously. Dr. said strength in injured leg is not quite 3 and needs to be at least 4 to not have any aid. I tried telling him being in immobilizer so long I felt really caused muscle atrophy and he didn't want to hear it. We still have a lot of ice here with daytime melting and night time freezing so I feel limited and have a fear of falling now. Did take a 2 mile walk with husband and dogs Saturday - even some up hill and was OK - husband held dogs (akitas). By yesterday afternoon too cold and too much ice (16 degrees and wind chill 2). For me this is slow going and I feel struggling to just get my life back. Not sure I'll ever really be able to do my job again - property management/construction supervision in that I would do 20-40 flights of stairs a day. And I see my national performance dog ratings slipping every month since I can't even practice, let alone compete.
