Final answer:
In the AC DogBone technique for ACL reconstruction, the correct size of the hole drilled is 4.0mm, allowing for secure placement of the fixation device.
Step-by-step explanation:
The AC DogBone technique in orthopedic surgery involves the creation of a specific size hole for the placement of the screw during Anterior Cruciate Ligament (ACL) reconstruction. The correct size of the hole that is drilled according to the current standard for the AC DogBone technique is 4.0mm (option D). This allows for secure placement of the fixation device while accounting for the strength and stability required for the graft used in ACL reconstruction.
