Objectives: The purpose of this study was to compare the load at failure, stiffness and mode of failure between three types of tibial tuberosity transposition fixation techniques: (a) pin and figure-8 tension band wire (Pin-TBW), (b) locking plate with pin and a tension band wire (Plate-Pin-TBW) and (c) locking plate with a pin (Plate-Pin).
Luxation/Subluxation
Category: Fracture Fixation and Implants - Luxation/Subluxation
Objective: To improve the accuracy of drilling during the repair of sacroiliac luxations (SILs) with a 3D-printed patient-specific drill guide (3D-GDT) compared to free-hand drilling technique (FHDT).
Study design: Blinded, randomized, prospective ex vivo study.
Sample population: Sixteen canine cadavers (20-25 kg).
Category: Luxation/Subluxation
Objective: To assess the role of the proximodistal and caudocranial relative position of the patellar ligament insertion on the tibia and patellar ligament length-to-patellar length ratio (PLL:PL) in small-breed dogs with and without grade II medial patellar luxation (MPL).
Study design: Retrospective study.
Sample population: Dogs weighing ≤15 kg, including 43 stifles with MPL and 34 control stifles.
Category: Luxation/Subluxation - Stifle
Objective: The aim of this study was to evaluate the bone deformities of the distal femur of Toy Poodles with medial patellar luxation (MPL) using computed tomography.
Category: Luxation/Subluxation
Objective: To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.
Study design: Multi-institutional retrospective cohort study.

Despite being one of the most commonly diagnosed causes of canine hind limb lameness, the pathogenesis of medial patellar luxation remains incompletely understood. Most cases are considered developmental with anatomical deformities leading to failure of the stifle extensor mechanism. These include coxa vara, coxa valga, reduced anteversion angle, distal external femoral torsion, excessive distal femoral varus, internal proximal tibial torsion, proximal tibial valgus, tibial tuberosity medialisation, patella alta and shallow trochlear groove.

Case description: A 7.5-year-old 37.8-kg (83.2-lb) sexually intact male German Shepherd Dog (dog 1) and a 2.6-year-old 28.2-kg (62.0-lb) sexually intact male Dutch Shepherd (dog 2), both apprehension police dogs, were admitted for evaluation of left and right thoracic limb lameness, respectively.
Category: Luxation/Subluxation - Tendon and Ligament Injuries
Objective: To report the preoperative evaluation, treatment with transarticular elastic external skeletal fixation (ESF), and outcome of a dog with bilateral medial patellar luxation (MPL) and stifle rotational deformity.
Animal: One nonambulatory, 2.5-month-old, 7.5-kg mixed-breed intact female dog.
Category: Luxation/Subluxation - Stifle
Objective: Evaluate the risk factors for reluxation and outcomes for dogs with a toggle rod construct.
Study design: Retrospective case series.
Animals: One hundred twenty-eight client-owned dogs.
