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.</p> </sec> <sec id="vsu12173-sec-0005" sec-type="section"> <title>Results</title> <p>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; <italic>P</italic> < .01).
