I'm at 15.5 weeks and decided I needed some help. I have little strength in my quad, cannot do stairs one foot over another, feel stiff and have pain in outer area and on knee. I can barely get in and out of a chair without that stabbing pain that occurs at a certaint point. I feel my life is very constricted with this weak quad. I checked out a new physiotherapy place that a friend has been happy with. I saw a wonderful PT who assessed my function, asked me what I wanted to accomplish and stressed that he would not do anything that caused me pain and that I was in control of any treatment. He was amazing and we agreed to work on strengthening and mobility. Nothing he did was painful, and when he suggested I try the bike, and could not perform one revolution, he stopped it right away. I feel he is treating me for my individual need, rather than the cookie cutter approach of the previous PT provided free from the health authority for TKRs. I have a good feeling about him, and this morning after, nothing hurts! I'll be trying this out twice a week and hopefully I can regain more function. He did say that about 20% of knee replacements take a longer time to heal, that it isn't anything I've done or not done, and it ISNT MY FAULT. I felt reassured hearing that. I hate that I'm in that 20% category, but it is what it is. And this morning although nothing from what he did hurts, my knee pain and stiffness was so annoying to me that I took an oxy 5mg. If I need it, I need it. I can't take anti-inflammatories so oxy is it. I have enough for a while, at least.
