3D angle: angle between the mechanical axes before and after derotation.

Tibial Plateau Leveling Osteotomy (TPLO) is a common surgical procedure performed on dogs to treat cranial cruciate ligament disease (CrCLd), which is a significant cause of hind limb lameness.

Tibial tubercle osteotomy with vs. without distalization yielded low rates of postoperative complications. Both techniques yielded similar rates of arthrofibrosis, nonunion and reoperation.

medial closing-wedge osteotomy of the distal tibia. Derotation- lengthening osteotomy in case of fibula malunion. Stage II--excessive calcaneus valgus: add medial sliding calcaneus osteotomy.
