Osteoarthritis

OBJECTIVE:  To report synovial fluid lactate concentrations in normal and pathological canine joints.

STUDY DESIGN:  Controlled, prospective study.

OBJECTIVES:  To describe the use of the Fixin locking plate system for stifle arthrodesis in dogs and to retrospectively report the clinical and radiographic outcomes in six cases.

Category: Knee - Osteoarthritis

AIM:  To test whether intra-articular injection of porcine adipose-derived stem cells (ADSCs) can treat canine osteoarthritis (OA).

OBJECTIVE: To document the progression of disease after an unloading procedure when combined with arthroscopic debridement to treat osteochondrosis (OC) lesions affecting the medial humeral condyle in juvenile dogs without medial compartment disease.

STUDY DESIGN: Retrospective case series.

ANIMALS: Dogs with medial humeral condyle OC (n = 6)

The objectives of this pilot study were to develop a video fluoroscopy kinematics method for the assessment of the coxofemoral joint in cats with and without osteoarthritis (OA)-associated disability. Two non-OA cats and four cats affected by coxofemoral OA were evaluated by video fluoroscopy. Video fluoroscopic images of the coxofemoral joints were captured at 120 frames/s using a customized C-arm X-ray system while cats walked freely on a treadmill at 0.4 m/s.

Radiography, magnetic resonance imaging (MRI), and ultrasonography are commonly used for diagnosis of shoulder osteochondrosis and osteochondritis dissecans (OC/OCD) in dogs, however there is a lack of published information on the relative diagnostic sensitivities of these modalities. The purpose of this prospective study was to compare diagnostic sensitivities of these modalities for detecting shoulder OC/OCD in a group of dogs, using arthroscopy as the reference standard.

OBJECTIVE:  To assess the medium- to long-term functional outcome of cats after femoral head and neck excision (FHNE) using an owner-completed questionnaire.

Elbow dysplasia is a heritable disease that is a common cause of lameness and progressive elbow osteoarthritis in young large breed dogs. The Orthopedic Foundation for Animals (OFA) screens elbow radiographs, and assigns grades 0-3 based on presence and severity of bony proliferation on the anconeal process. Grade 1 is assigned when less than 3 mm is present and considered positive for dysplasia.

OBJECTIVE:

To evaluate medium and long term effects of sliding humeral osteotomy (SHO) in dogs.

STUDY DESIGN:

Prospective study.

ANIMALS:

Dogs (n = 32).

METHODS:

Data (2008-2010) collected from medical records included force plate data, radiographs, and a 15 question owner survey of dog soundness before SHO and at final evaluation.
