Your knee is nicely bent too isn't it? Are you sure you need that MUA?
In two weeks my knee flexion has improved by about 20 degrees after seemingly being stuck for ever at about 85/90, and it now feels so much more likely that it will improve. This has been at the expense of my extension, which has gone from 0 to about +5 because I've been concentrating more on improving the bend.
I've just finished reading the fantastic, critically acclaimed book 'Complications' by Atul Gawande, a surgeon. It offers a fascinating insight into the medical profession.
One important message that comes through is the variation in opinion on virtually everything they do! Of course they all follow standard protocols, but they also have very different ideas about what is best and when.
Go to one doctor, get one opinion and treatment (very much based on their own experiences and interpretation, not necessarily always the perfect solution, but well intentioned) and go to another and get offered something completely different.
Such is life I guess. All the best for the MUA, I will be crossing fingers and toes (and even my knee) for a great outcome!
