Hi Canuck, Thank you for your reply.

The Wikipedia reference-linkMRI was lost inbetween the hospital being closed, going to new hospital and then being referred to a 3rd extra-special hospital. The 1st hospital didn't have the actual scan pic but did have the write up. It seems that all is ok apart from the patella being off track, no bony spurs or anything else mentioned. The 3rd hospital has been trying to get hold of MRI for 8 months.

When they physically manipulate my knees they don't exactly hurt at the time but a couple of minutes later they feel very sore. There seems to me to be a lot of movement and popping in my knees, but they said it was normal.

I'm going to take your advice and go back to physio. Gait re-training was a wonder, I thought I'd not be able to walk anymore as it was so painful.

Thanks very much.
