Patellar luxation is one of the more common orthopaedic diseases of dogs and is relatively frequent in some toy breeds, including the Chihuahua and Bichon Frise.

OBJECTIVE: To evaluate long-term loading patterns using subchondral bone density (SBD) distribution of the tibial plateau after tibial plateau leveling osteotomy (TPLO) and tibial tuberosity advancement (TTA).

STUDY DESIGN: Cross-sectional study.

Many researchers are interested in femoral conformation because most orthopaedic problems of the long bones occur in the femur and its joints. The neck-shaft (NSA) and the anteversion (AVA) angles are good predictors for understanding the orientation of the proximal end of the femur. The varus (aLDFA) and procurvatum (CDFA) angles have also been used to understand the orientation of the distal end of the femur.

The objective of this study was to describe the patient population of dogs with cranial cruciate ligament (CrCL) deficiency that were prescribed a stifle orthosis.

Even though radiography is one of the most frequently used imaging techniques for orthopaedic disorders, it has been demonstrated that the interpretation can vary between assessors. As such, the purpose of this study was to examine the intraobserver and interobserver agreement and the influence of level of expertise on the interpretation of radiographs of the stifle in dogs with and without cranial cruciate ligament rupture (CCLR).

OBJECTIVE: To compare pelvic limb joint kinematics and temporal gait characteristics during land-based and aquatic-based treadmill walking in dogs that have undergone surgical stabilisation for cranial cruciate ligament deficiency.

OBJECTIVE: To describe a technique and normal findings for arthroscopy of the stifle in rabbits.

STUDY DESIGN: Cadaver study.

ANIMALS: Twenty cadaveric stifles from New Zealand White rabbits were examined.

METHODS: The arthroscope was placed through a medial portal, and instrument portals were created on the lateral aspect of the joint. The same portals were used for examination of the entire joint and palpation of structures with a probe.

OBJECTIVE: To describe a new technique to control intraoperative hemorrhage during tibial plateau leveling osteotomy (TPLO) and report subsequent short-term and long-term complications.

STUDY DESIGN: Retrospective case series.

ANIMALS: Nine dogs with arterial hemorrhage during TPLO.

BACKGROUND: Complete rupture of the cranial cruciate ligament (CrCL) in dogs causes profound disturbance to stifle joint biomechanics. The objective of this study was to characterize the effects of cranial cruciate ligament (CrCL) insufficiency on patellofemoral (PF) kinematics in dogs during walking. Ten client-owned dogs (20-40 kg) with natural unilateral complete CrCL rupture were included. Dogs underwent computed tomographic scans to create digital bone-models of the patella and femur.

OBJECTIVE: To describe and report the outcomes of a novel modified Maquet-tibial tuberosity advancement (mTTA) technique in dogs with naturally occurring cranial cruciate ligament (CCL) rupture, compared to a traditional tibial tuberosity advancement (tTTA) technique.

STUDY DESIGN: Descriptive report and retrospective clinical cohort study.

SAMPLE POPULATION: Dogs (n = 70) treated via tibial tuberosity advancement (TTA).
