JK: I envy you the ease with extension. I have longstanding back issues, and I need my legs to be balanced so I will not cause any more problems. I had arthroscopic surgery on same knee 11 months ago, and, being an overachiever, was so proud of my 130 degree flexion in no time at all, and I suspect that I neglected the extension a little bit. With all the walking for exercise, and gardening, etc., I do, the slight imbalance MAY have hastened the progression of arthritits to the point where pain was constant and limiting. So this time, I’m getting it straight before getting it bent (it’s ok anyway, around 110 to 115 after 4 weeks). As to opioids: same surgeon did 2 shoulder arthroscopies - 1 each side -, 1 knee arthroscopy, 1 knee replacement. Each and every time he was generous with prescription, and each and every time I returned the leftovers. I hate opioids with a passion, but nothing beats a decent night’s sleep when you had surgery and pain.
