Qidam,
My experience (many years ago, I admit) with the CAA was excellent over a similar problem. Fractured femur, I went direct to CAA Medical in London, where the Senior Medical Examiner put a requirement of 90 degrees flexion on the knee to be fit to fly.
5 weeks later, fronted up at CAA, had a medical and a bit of a discussion, and was sent back to work. Biggest hurdle was the oil company having a pilot on a walking stick, living on a rig in the Brent Field
The pin took a year to work it's way out of the femur, so don't take any flannel about not being able to fly with metal work still in your body. I did have a check flight with the company on return to work, with emphasis on hydraulic out work, to ensure the leg had the strength to handle the pedals.
Nigel, DB was quite a fellow. I've still got his autograph
