Plain-English summary
A group of dogs undergoing surgery for knee problems related to cranial cruciate ligament disease had their tibial plateau leveling osteotomy (TPLO) evaluated to see how accurately the surgery was performed. Two different surgical systems were used: one with just an alignment jig and another that included a saw guide. The results showed that the dogs in the group using the saw guide had more precise cuts, which helps improve recovery and function after surgery. Overall, using the saw guide led to better outcomes for the dogs.

Abstract
OBJECTIVE: To report the accuracy of osteotomy position in dogs undergoing tibial plateau leveling osteotomy (TPLO) and to evaluate the effect of 2 different TPLO jig and saw systems on tibial osteotomy position. STUDY DESIGN: Retrospective case series. ANIMALS: Dogs (n = 124; 134 TPLO). METHODS: Medical records (2004-2005; 2008-2011) and stifle radiographs of 2 groups of dogs that had TPLO to treat cranial cruciate ligament disease were reviewed. One group had a TPLO performed using an alignment jig system alone (Slocum group), whilst in the other group, an alignment jig system combined with a saw guide (Synthes group) was used. Postoperative radiographs were examined and the distance and direction of the centroid of the osteotomy was compared to the intended osteotomy position. RESULTS: The absolute distance of eccentricity (DOE) in the Slocum group (5.6 ± 2.5 mm) was significantly greater than that of the Synthes group (3.4 ± 1.8 mm; P < .01). DOE was caudal and distal in 79% of cases. CONCLUSIONS: Most tibial osteotomies were centered at a point distal and caudal to the intended osteotomy position. Use of a TPLO system with a saw guide was associated with more accurate placement of the osteotomy and more accurate leveling of the tibial plateau.
