Comparison of Hindlimb Conformation in Cats with and without Medial Patellar Luxation
Authors: Andrew James Carey Beer, Sorrel Langley-Hobbs, Alex Belch

Objectives: Medial patellar luxation (MPL) is the most common developmental cause of hindlimb lameness in cats. The association between femoral and tibial conformation and MPL measured on computed tomography (CT) has not been reported in cats. The aims were to report femoral and tibial conformation in cats with and without MPL and to report normal femoral and tibial angles.

Custom-built constrained uniaxial and rotating hinge total knee replacement in cats: Clinical application, design principles, surgical technique, and clinical outcome
Authors: Noel Fitzpatrick, Diogo C Miraldo, Jay Meswania

Objective: To describe the design principles and evolution, surgical technique, and outcome for custom constrained (uniaxial and rotating hinge) total knee replacement (TKR) in cats.

Study design: Retrospective case series.

Animals: Nine cats with traumatic stifle luxation (n = 8) or severe distal femoral deformity (n = 1) were considered suitable candidates.

Comparison of Intra-and Postoperative Complications between Bilateral Simultaneous and Staged TPLO with Arthroscopy in 176 Cases
Authors: Raz Peress, Sebastian Mejia, Marcos Unis, Giovanni Sotgiu, Simone Dore, Kenneth Bruecker

Objective: The aim of this study was to compare the resulting short-term complications after simultaneous (SIM) or staged (ST) tibial plateau levelling osteotomy (TPLO) in patients that presented with bilaterally torn cranial cruciate ligaments.

Study design: This was a retrospective study.

Progressive Loss of Implant Fixation in a Preclinical Rat Model of Cemented Knee Arthroplasty
Authors: Kenneth A Mann, Mark A Miller, Jeffrey K Rossow, Megan E Tatusko, Jason A Horton, Timothy A Damron, Megan E Oest

Aseptic loosening of total knee arthroplasty continues to be a challenging clinical problem. The progression of the loosening process, from the initial well-fixed component, is not fully understood.

In-Vivo Three-Dimensional Knee Kinematics in Goats With Unilateral Anterior Cruciate Ligament Transection
Authors: Ana Bascuñán, Mariajesus Soula, Kristina K Millar, Adam Biedrzycki, Scott A Banks, Daniel D Lewis, Stanley E Kim

Although the goat is an established animal model in anterior cruciate ligament (ACL) research, in-vivo kinematics associated with ACL deficiency have not been previously described in this species.

Femorotibial kinematics in dogs treated with TPLO for cranial cruciate ligament insufficiency: An in vivo fluoroscopic analysis during walking
Authors: Tinga S, Kim SE, Banks SA, Jones SC, Park BH, Burtch M, Pozzi A, Lewis DD.

OBJECTIVE: To determine the ability of tibial plateau leveling osteotomy (TPLO) to address abnormal femorotibial kinematics caused by cranial cruciate ligament (CCL) rupture during walking in dogs.

STUDY DESIGN: Prospective, clinical.
