Update - It's now 2 years and 3 months. Progress has been slow but there has been progress. A very brilliant sports med doc concluded that scar tissue is impeding my ability to bend and surgery to remove the scar tissue could precipitate even more scar tissue and less ROM. Therefore, surgery like MUA is not an option. Instead, using UltraSound to guide him, he inserts a long needle into the TKR knee and tries to separate the scar tissue and get it to "line up". After 1 year of this procedure (every 4-5 weeks), I increased my ROM by 2-3 degrees. That doesn't sound like a lot, but every degree helps. I can walk down stairs w pain level 4 versus pain level 10. For the first time in more than 2 years, I can put pants on by lifting and bending the TKR knee. He treats my other knee, non TKR, with a steriod and Hylaronic Acid. Quite frankly, this doc has made the best out of my disastrous experience w knee surgery. FYI, I exercise 6x per week, 1.5 hrs per day, using weight machines including treadmill and bike. If I lead a sedentary life, the TKR knee probably would have worked out better.
