To describe the clinical findings of dogs that sustained patellar fractures after tibial plateau leveling osteotomy (TPLO).
Retrospective case series.
Dogs with patellar fractures that occurred after TPLO surgery (n = 6).
Medical records (November 1, 2008-October 31, 2010) were reviewed to identify dogs with patellar fracture occurring after TPLO.

This is a report of mandibulo-zygomatic arch synostosis in a dog 7 mo after trauma to the maxilla. Advanced diagnostic imaging was considered essential for characterization of the condition and treatment planning. Surgical excision of the bony proliferation and physiotherapy resulted in improved function within 6 wk.
Computer-based gait analysis of dogs: Evaluation of kinetic and kinematic parameters after cemented and cementless total hip replacement.
To date it is unclear whether cementless total hip replacement (THR) in dogs is of clinical advantage in comparison to cemented THR with regard to lameness improvement. Thus the aim of this study was to compare objectively the development of the gait pattern after cemented and cementless THR in dogs. For this purpose, 18 adult dogs with hip dysplasia underwent computer-based gait analysis on an instrumented treadmill prior to unilateral THR and then again ten days, four weeks and four months after surgery.
Caudal paw displacement during movement initiation and its implications for possible injury mechanisms.
Objectives: The purpose of this study was to quantify and determine the degree to which dogs experience negative displacement of the paw during movement initiation on natural surfaces, the frequency of that displacement, and whether or not the negative displacement could yield injuries. Methods: Seven retired racing Greyhound dogs were selected to participate in sprint starts on two natural (non-vegetated and vegetated) surfaces. Kinematic analysis was conducted to quantify the displacements.
Total joint replacement is now considered a routine surgical option for small animals with advanced joint disease. This review highlights the current state of the art in total hip, elbow and knee replacement in small animals, as well as the potential for application to other joints such as the intervertebral discs, hock and shoulder. Advances in cementless fixation, the use of less-invasive, bone-sparing procedures, and the development of custom implant options for revision surgery and oncologic reconstruction will be discussed.
Use of bathroom scales in measuring asymmetry of hindlimb static weight bearing in dogs with osteoarthritis.
Objective: The study assessed the use and reliability of bathroom scales as an objective measurement tool, and setting a normal variance of static weight bearing between hindlimbs. Methods: Two groups of dogs were tested: a healthy control group (n = 21) and a group (n = 43) of dogs with confirmed osteoarthritis in at least one stifle joint, with or without hip joint osteoarthritis. Static weight bearing was evaluated manually and measured with two bathroom scales. An orthopaedic examination was done and dynamic weight bearing was measured using a force platform.
Low-level laser therapy reduces time to ambulation in dogs after hemilaminectomy: a preliminary study.
A prospective study to determine if low-level laser therapy and surgery for intervertebral disk herniation encourage ambulation faster than surgery alone.
Objective-To assess joint kinematics in dogs with osteoarthritis of the hip joints during walking up an incline or down a decline and over low obstacles and to compare findings with data for nonlame dogs. Animals-10 dogs with osteoarthritis of the hip joints (mean ± SD age, 6.95 ± 3.17 years; mean body weight, 34.33 ± 13.58 kg) and 8 nonlame dogs (3.4 ± 2.0 years; 23.6 ± 4.6 kg). Procedures-Reflective markers located on the limbs and high-speed cameras were used to record joint kinematics during walking up an incline or down a decline and over low obstacles.
Kinetic and kinematic analysis of the right hind limb during trotting on a treadmill in Labrador Retrievers presumed predisposed or not predisposed to cranial cruciate ligament disease.
Objective-To identify gait characteristics during trotting on a treadmill in nonlame Labrador Retrievers presumed predisposed or not predisposed to cranial cruciate ligament disease (CCLD). Animals-Clinically normal Labrador Retrievers presumed predisposed (n = 10) or not predisposed (7) to CCLD. Procedures-The right hind limb of each dog was classified by use of a predictive score equation that combined tibial plateau angle and femoral anteversion angle as presumed predisposed (high score [> -1.5]) or not predisposed (low score [≤ -1.5]) to CCLD.
