Speed, coke and steroids could change that.
Oh sure, I know people whose lives have changed from them!
So here's the scoop with aquatic therapy. The therapist is the most important part until you develop a routine. It just takes too much time to figure stuff out on your own. The pool I use is salt water and ~95 degrees. A regular heated pool is ~85 degrees and requires 'warm up' exercises to stretch out.
Stop stretching at the onset of the 'stretch' sensation and work the stretch in those parameters, increasing the minimum range of comfortable motion. It's kind of a different approach to PT, I guess. I mean it all works so long as you do the work but taking care to not hurt yourself during recovery only helps the recovery.
Now the good part: drugs. Use the appropriate level of pain killers to get you through the PT whether, it be pot or pills. My guess is you need pills. I'm down to pot and the regular Asprin/Tylenol/NSAIDs now but right after a knee replacement about a year ago, opiates were required.
My PT people this time around were both top notch. The first two surgeries were arthroscopic and those PT people were good too, just not as good as the team I stumbled on after the third surgery (full knee joint replacement). Don't post any more pic's on my behalf. PM that sh!t straight to GO-NAD! but my leg was black, way blacker than yours and the knee was twice the size. To make matters worse, I'm a huge pussy.
... and I had to ditch Face Book because I was spending time on that when I could have been doing PT.
