Effect of calcanean bone-tunnel orientation for teno-osseous repair in a canine common calcanean tendon avulsion model.

All drilling techniques and bone-tunnel orientations tested in the study reported here offer viable options to reattach the CCT to the calcaneus. Surgeons should evaluate how bone-tunnel orientation may affect placement of adjunctive fixation methods to stabilize the talocrural joint after primary CCT repair in dogs.
