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.
