“…The difference in the distance of eccentricity from the center of the intended osteotomy to the center of the actual osteotomy did not reach significance. However, the mean distance of eccentricity in the present study was similar to that previously reported ( 39 , 45 ). The conventional TPLO method displayed a tendency for the direction of eccentricity to the caudal and distal deviation, consistent with the findings of a previous study ( 27 ).…”

Objective: To prospectively evaluate the effect of a computed tomography (CT)-based three-dimensional (3D) printing surgical guide on surgical accuracy of tibial plateau leveling osteotomy (TPLO).Study Design: Cadaveric study.Animals: Canine cadaveric hindlimbs (n = 14).Methods: TPLO was performed on cadaver hindlimbs disarticulated at the coxofemoral joint to compare and evaluate the conventional TPLO method (n = 7) with one that used customized 3D printing surgical guides (n = 7). The operation time and postoperative tibial plateau angle (TPA) of the osteotomy were evaluated. Moreover, the osteotomy inclination, torsion, and distance and the direction of eccentricity were assessed using CT reconstruction.Results: Significant differences in the operation time (p < 0.001), postoperative TPA (p < 0.05), osteotomy inclination (p < 0.05), and osteotomy torsion (p < 0.05) were observed.Conclusion: The use of TPLO surgical guide reduced the operation time and inaccurate osteotomy.Clinical Significance: The surgical technique applied with a customized 3D printing surgical guide could be used to perform osteotomy and TPA adjustment more precisely than conventional TPLO.

“…While the y-axis represented the tibial long axis, the x-axis was perpendicular to the tibial long axis. Additionally, the eccentric direction of the distance to the center of actual osteotomy was evaluated ( 27 , 39 ). Data were analyzed for significant differences in the distance of eccentricity between the two methods.…”

To evaluate the effectiveness of a novel crescent-shaped tibial plateau-leveling osteotomy (TPLO) saw guide (crescent guide) to assist with saw control in novice participants.Study design: Ex vivo study.Sample population: Synthetic bones (n = 54) and medium sized dog pelvic limbs (n = 36).Methods: The 6 participants (interns and residents) without any prior experience performing a TPLO each performed 9 osteotomies on synthetic tibia models, and 6 osteotomies in cadaveric limbs of medium-sized dogs. Osteotomies made with the crescent guide were compared with those made with a standard jig and a radial saw guide with a jig. Osteotomy angulation, distance of eccentricity (DOE), and medial tibial cortical damage (synthetic bone models only) were measured from calibrated photographs. Participants rated their experiences with each technique. Results: There was no difference in the DOE, coronal or axial osteotomy angulation between the 3 alignment devices for synthetic bone models or cadavers. Average medial cortical damage with the crescent guide (3.8 ± 7.3 mm 2 ) was lower than with the radial guide (35.7 ± 27 mm 2 ) and standard jig (51.2 ± 63.2 mm 2 ) guides (P = <.01). Five of 6 participants preferred the crescent guide over the standard jig and radial guide. Conclusion:There was no difference in accuracy of osteotomy positioning but using the crescent guide resulted in lower cortical damage and more favorable participant perceptions. Clinical relevance:The crescent guide may improve control of the radial saw during TPLO in novice surgeons but does not appear to aid accurate osteotomy positioning. | INTRODUCTIONExecution of the radial osteotomy during tibial plateauleveling osteotomy (TPLO) is technically challenging and can be one of the most intimidating aspects of the There was no proprietary interest or funding provided for this project.
