That must have been very uncomfortable. Two syringes ? I fractured my knee, 40 years ago, and I had to drag myself to the ER to get it assessed. It was at a teaching hospital, where they promptly had a 3d year med student stick a syringe in my knee to drain it. That was worse than any other thing I've had done.
I hope you can abide by the brief restrictions for the next week. It must feel very boring, but it does sound like there will be complete recovery of the fracture.
