Hi Dannie,
what happened to your elbow in order to have it for surgery? Was it broken or something? The things they did is/was not a simple release, the elbow must have some scar tissue now. Are you happy with the way it looks now or do does it makes you angry?
First I would like to know whether there are any objective changes seen on imaging, eg X-ray/MRI/Ultra sound. Second, how much movement is there in the elbow? How much mobility has the joint left. Finally, did you do general exercises fot the elbow, to flexion and extension? Does it respond differently to those movement directions?
This is a dreadfull story for a youngster who likes to sport.
