Today is 6 months since my bilateral knee replacements were done. Take heart everyone.....between 5 and 6 months I noticed a big improvement,,,in everything. Have just stopped physio as I dont feel I need it now as I have rom of 146 in my right knee and 137 in my left. I am pain free, even when getting up from sitting for a while, can walk as much as I like and really dont feel as if my knees are 'fake' Am now ready and able to do an overseas trip in 5 weeks and life is good. Take heart everyone...it gets better and is so worth the effort.
