Blender > Unity - help with unwanted bone twisting/rotation?

After importing a few animated models into Unity I ran into a bit of a problem. This is my first time encountering something like this and it doesn't seem to be happening to any other models I've created.

As you can see the model has it's proper rotation set up in Blender (I use the same setup for every model) HOWEVER, Unity is showing me something entirely different.

I have tried exporting directly to FBX instead of using the blend file but that doesn't work. I have also tried changing the bone roll in blender but it badly distorts my model and all of it's animations. I just can't seem to get this to work. Does anyone have any suggestions or fixes?
