It may still be early for MUA but looking at your history, it's no surprise you would develop scar tissue. Some orthos think early MUA is preferable. Best thing you can do is rest like crazy, and ice and elevate like crazy, until your procedure. And the same afterward. Scar tissue thrives on inflammation. So pain and swelling are clues to combat inflammation. And a word of advice: post MUA some or maybe most PTs think that the more you "work" in PT, the harder you push, etc., etc., the greater your chances of increasing range of motion. And I believe that the opposite is true. The more you rest, the better your chances. But it's important every day, maybe twice a day, to do some good, long, slow stretches (both extension and flexion). You want to encourage that range of motion but never to pain, only to the discomfort stage. If you stick with that -- stretching daily, keeping your knee as calm as possible -- your chances of good ROM will be better. I've done it both ways. I also used CPM while watching TV. I do believe that this is one of the few situations where CPM can be an aid. I started low and increased the bend very slowly, again, never in the pain zone.
