TOPIC: FOOT & ANKLE
What is the optimal biomechanical alignment for an isolated tibiotalar (ankle) arthrodesis to ensure a functional gait cycle and minimize the accelerated progression of adjacent joint osteoarthrosis?
A
Neutral dorsiflexion, 0 to 5 degrees of valgus, and 5 to 10 degrees of external rotation
B
5 degrees of plantarflexion, neutral coronal alignment, and 15 degrees of external rotation
C
5 degrees of dorsiflexion, 5 degrees of varus, and neutral rotation
D
Neutral dorsiflexion, 5 degrees of varus, and internal rotation matched to the contralateral limb
