Objectives: To evaluate the ability of an alignment jig/saw guide to reproduce appropriate osteotomy positions in the tibial plateau leveling osteotomy (TPLO) in the dog. Methods: Lateral radiographs of 65 clinical TPLO procedures using an alignment jig and freehand osteotomy performed by experienced TPLO surgeons using a 24 mm radial saw blade between Dec 2005 - Dec 2007 and Nov 2013 - Nov 2015 were reviewed. The freehand osteotomy position was compared to potential osteotomy positions using the alignment jig/saw guide. The proximal and distal jig pin holes on postoperative radiographs were used to align the jig to the bone; saw guide position was selected to most closely match the osteotomy performed. The guide-to-osteotomy fit was categorized by the distance between the actual osteotomy and proposed saw guide osteotomy at its greatest offset (?1 mm = excellent; ?2 mm = good; ?3 mm = satisfactory; >3 mm = poor). Results: Sixty-four of 65 TPLO osteotomies could be matched satisfactorily by the saw guide. ... : PLOSONEcomplete data set. (TPLO alignment jig-saw guide)Raw data collected for two groups of clinically performed TPLOs (a crescent osteotomy of the proximal tibia designed to alter the craniotibial shear force as a result of a cranial cruciate deficient knee). Group 1 (2005-2007): freehand osteotomies with jig only; Group 2 (2013-2015): freehand osteotomies with jig only. Group 1 follows recommendation at that time to place proximal jig pin through center of medial collateral ligament (MCL). Group 2 follows the later recommendation to place the jig pin behind the MCL. The objective of the study is to determine if a saw guide attached to the jig can match the positions of the osteotomy performed by experienced surgeons, and also is it can replicate the ideal osteotomy location. The data file are all measurements obtained from these clinical cases that compares guide-to-osteotomy fit and the appropriateness of the osteotomy based upon current published guidelines. All methods are described in the manuscript. ...
