Thanks for the advice
@KTO , I may well look into that although I think right now I need to let my knee settle a little.
@Jamie , I am definitely going to take it easier as it is so early on - I will fight my inner voice that wants to measure, measure, measure and compare!
I see the doc in just under two weeks, so I'm going to halt the physio unit then and see how I get on just resting, elevating and doing the exercises I have been doing. If my bend improves from around 80/90, I will know this is the way forward.
My rationale for this is that I had previously achieved 100 degrees of bend and less swelling on my own. This was before my first physio session two weeks ago, but ever since I started physio it has just gotten worse, in particular this week when the PT pushed my knee to the limit during both sessions, resulting in swelling and pain. It has also impacted my walking, which was fine until the end of last week, so enough for now.
Following the PT session on Friday, my leg was achy and swollen yesterday (Sat). This seems counter productive to me and further supports the approach advocated by BS.
Today I have rested, iced and elevated and done my basic exercise sets. Already I can feel the knee relax a bit more, with swelling staying down to my wake up morning levels and my walking back to where it was.
I'm hopeful this approach will yield a better result over the next couple of weeks. There's no hurry of course, and time will tell.
