With venison I always bone from the inside, I. E work the knife all around the bone then cut off the bone at the joint leaving the bottom bone as a bit of a handle to hold when carving.
Is that how you did it or did you cut through the meat down the bone so as to end up with a slab of meat.
It doesn't matter which way really, one way though requires more tying, but can be stuffed better for nice presentation.
