Bone Isotope scan!

Well, today was the day of my bone isotope scan.
I was a little nervous, but grateful that after this scan i would know for sure what needed to be done to me!
The bus dropped me at the private clinic where i was to have my scan and i headed up to the doctor...sorry, correction...nuclear physician's office, for my scan.
I was asked to lie down and they injected me with the substance in my right arm. It was luckily only a needle full and didnt hurt too much.
I was asked to return in a couple of hours, so i headed off for sum breakfast down the road.
When i returned, i lay down in a machine not dissimilar to an MRI machine.
I lay still while the machine slowly spun around me and took images of my lower body.
The whole procedure took about an hour, and then i was on my way.
Or so i thought.
I had the bus drivers number to call when i was done, so i gave him a call and he said that he was on the road back to where i had come from, 2h away, and that he would get another bus or ambulance to pick me up.
After 3 more phone calls over the next couple of hours, he eventually returned back to pick me up 3h after my original call!
Then i was off to the provincial hospital to get my file. They had to phone up to the orthopaedic section to let them know i was coming as it was already so late in the day.
When i got upstairs, i sat and waited another 2 hours before the specialist i had been seeing all along came walking up to me with another man. He introduced us, and he turned out to be the head of the orthopaedic department.
We went into the consultation area and he pulled out my scan results and put them up on the xray viewing machine.
The scan showed up that there was still action around the fracture sites, which meant that the bones were still healing. He told me that bones can continue to heal for up to 2 years, so based on the scan, he would not recommend another op before that period is up. This would only be in October next year. And obviously only if the bones still weren't grown back together by then.
The other area of the scan which was just a big blotch of activity was the knee!
He said that this indicated that the knee was extremely unhappy, which is why i am experiencing a lot of pain in that area.
He said that until they go in and see what is the matter they would not be able to do anything about it.
So, with my knee scope already booked in for March (thank God, as the new date had it not already been booked earlier, due to demand, was only in May!), all that was left to do was strengthen the quad muscles as much as possible before the op.
He told me that normally he would want the affected legs quad muscle to be 120% of the good leg's strength. At the moment i can just about lift my leg straight form a bent position, but i am sure i could lift more were it not for the pain in my knee.
He said that it was a bit of a catch 22 i was in as i needed to exercise the quad muscle even though the exercise meant hurting my knee!
We also checked my blood tests and they were perfect. He said that he had never seen an infection reading as low as mine. Everything was great.
So, basically what needs to happen is that over the next 3 months up to the 5th March, i need to work on my atrophied quad muscle as much as possible in order to get it ready for the op which will immobilize it again for possibly another month or more.
I have done a bit of research online and have found that an electric muscle stimulator might be very helpful for my quad muscle as it could exercise the muscle without the need for me bending my knee.
I have found one online and am in the process of ordering it.
So, another visit to the hospital and another different diagnosis!
At least this one is based on the scan, and not some doctors hearsay.
Apparently the recovery period after the scan is 3-4 months, so this would mean that all things going well, i will be walking by June/July 2013...
But i wont know for sure what the outcome will be before the scope in March. I am still very optimistic that the scope will rectify the problems with my knee, and that come the middle of next year i will finally take my first steps!
