Hello Mrs Cricklewood I thought I'd come and visit you!! Surprising how quick the flight was! I'm also trying to walk about the house without aids but am mindful to walk tall, try to bend the knee, (heel then toe- physio's instructions) and not waddle (slowly)! However, first thing in the morning I need my stick and also often during the evening.
I have found putting my leg on the second stair and trying to gently push into it at 90%ish angle (or what you can manage comfortably) has helped as has the bike, but i'm only a learner on that yet and am building up to any distance. I'm only managing a few minutes at the moment but I can feel it is helping with the bend but still working on trying to get the old leg straight without too much success.
Thanks for your wonderful support.
Big hugs

You are smart to take it easy today Soon you will be able to string those activities together and add to them.
I have been busy looking after my son and friends, cooking and washing etc the last couple of days (they've just gone) and although exhausted and knee a bit sore, so glad I have been able to do it!

I had another physio session today..my physio measured my knee bend before we started 55 ! That is woeful ! After half an hour he measured me again and it was 65 ! Then I had a session in the heated pool and did my stretching and bending and walking exercises. there was only one other lady in there and guess what..she had had a knee replacement so of course we compared notes...she has to have her other knee done in Jan ..I told her about this forum and she was going to check it out ! Then when I got home there was a message on the answering machine from the hospital about my MUA ! Wondering where all my paperwork is..I will tell you where it is..still in my bag cos I aint going to have it ! HELP !!!! Come on knee...BEND !!!!! 
. Funny you would say that because my physio actually showed me a few stretches I can do plus suggested I put a heat pack or hot water bottle on the top of my leg to loosen that up as well ! Where it hurts is weird to explain..sometimes it is I feel like my knee is so tight it is going to explode..sometimes it is the top of my scar..similar to what you described. The hospital phoned up today and said my surgeon said if I could get to around 90% bend in the next 4 weeks they were happy to cancel my MUA..that got me thinking...what if even though I am going to do my darndest to get my knee to 90% by then..what if I can't !! Just something else for me to worry over..............
