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.

Study design Clinical case report.
Category: Luxation/Subluxation
Objective: The aim of this study was to describe a new surgical method of segmental femoral ostectomy for the reconstruction of the femoropatellar joint (FPJ) in dogs with medial patellar luxation (MPL) grade IV.

OBJECTIVES: To describe reduction techniques and clinical outcome in a series of traumatic elbow luxations in cats.
Category: Elbow - Luxation/Subluxation
Case summary: A 1-year-old spayed female domestic shorthair cat presented for evaluation of a non-weight bearing right pelvic limb lameness after falling from a 4 m height. On orthopedic examination there was substantial swelling and pain on manipulation of the right pes. Radiographs were obtained under sedation, and these revealed dorsoproximal luxations of the third, fourth and fifth metatarsophalangeal joints, and lateral rotation of the second digit.

Coxofemoral luxation is the most common type of joint luxation observed clinically in dogs.
This retrospective study determines the complications and outcomes of open reduction and internal fixation of coxofemoral luxations using a toggle rod stabilization in 58 dogs. The purpose of the study was to compare the results with previous studies to ascertain commonalities and differences.
