Complications and Long-Term Outcomes after Combined TPLO and TTT for Treatment of Concurrent CCL Rupture and Grade III or IV Medial Patellar Luxation

Authors: Giovanna Redolfi, Jean-Guillaume Grand

Objectives: This study aims to report complications and long-term outcomes of combined tibial plateau leveling osteotomy and tibial tuberosity transposition (TPLO-TTT) for treatment of concurrent cranial cruciate ligament rupture and medial patellar luxation (MPL).

A mismatch of planning and achieved tibial plateau angle in cranial closing wedge surgery: An in silico and clinical evaluation of 100 cases

Authors: Charlotte Banks, Gareth Michael Couper Jones, Richard Lawrence Meeson

Objective: (1) To determine whether Oxley's modified cranial closing wedge osteotomy (CCWO) results in a tibial plateau angle (TPA) of 5° in silico, (2) compare in silico to clinical postoperative TPA and (3) determine the impact of ostectomy distalization in silico.

Study design: Cross-sectional retrospective radiographic in silico study.

Comparison of three-dimensional printed patient-specific guides versus freehand approach for radial osteotomies in normal dogs: Ex vivo model

Authors: Adam Townsend, Julien Guevar, Bill Oxley, Scott Hetzel, Jason Bleedorn

Objective: To compare the accuracy of three-dimensional (3D) printed patient-specific guide (PSG) with a freehand (FH) approach for radial osteotomies in ex vivo normal dogs.

Study design: Experimental study.

Animals: Twenty four ex vivo thoracic limb pairs from normal beagle dogs.

Meniscal Load and Load Distribution in the Canine Stifle after Modified Tibial Tuberosity Advancement with 9 mm and 12 mm Cranialization of the Tibial Tuberosity in Different Standing Angles

Authors: Johannes Maximilian Schmutterer, Peter Augat, Markus Greinwald, Andrea Meyer-Lindenberg

Objectives: The aim of this study was to investigate the kinetic and kinematic changes in the stifle after a modified tibial tuberosity advancement (TTA) with 9 and 12 mm cranialization of the tibial tuberosity in different standing angles.

Effect of Plate Type on Tibial Plateau Levelling and Medialization Osteotomy for Treatment of Cranial Cruciate Ligament Rupture and Concomitant Medial Patellar Luxation in Small Breed Dogs: An In Vitro Study

Authors: Melania Dallago, Alessandro Boero Baroncelli, Caleb Hudson, Bruno Peirone, Evelien De Bakker, Lisa Adele Piras

Objective: The main aim of this study was to determine the effective magnitude of proximal tibial segment medialization achievable during tibial plateau levelling and medialization osteotomy (TPLO-M) with Fixin 1.9-2.5 mm pre-contoured T plates with three different offsets.

Fully Guided Synthetic Osteochondral Resurfacing of a Large Stifle OCD Lesion Using a Patient-Specific Implant and Drill Guides

Authors: Jasmine Moser , Georg Haimel , Karen Barker-Benfield , Katharina Leschnik , Peter Böttcher

Synthetic anatomical reconstruction of extensive, oval osteochondrosis dissecans (OCD) defects remains a challenge due to the ‘one shape fits all’ design of commercial round implants. This is further complicated by the inherent inaccuracy of free-hand implant positioning procedures.
