Osteoarthritis

OBJECTIVE: To evaluate the effect of arthroscopic lavage and repeated intra-articular administration of antibiotic in adult horses and foals with septic arthritis.

STUDY DESIGN: Retrospective clinical study.

ANIMALS: Adult horses and foals with septic arthritis (n = 62).

OBJECTIVE: To describe the clinical signs, surgical treatment, and outcome of septic arthritis of the coxofemoral joint in foals.

STUDY DESIGN: Retrospective clinical study.

SAMPLE POPULATION: Foals (n = 12) with confirmed sepsis of the coxofemoral joint.

BACKGROUND: There is limited information available concerning normal equine meniscal morphology, its degeneration and role in osteoarthritis (OA).

OBJECTIVES: To characterise normal equine meniscal morphology and lesions and to explore the relationship between equine meniscal degeneration and femorotibial OA.

STUDY DESIGN: Ex vivo cadaveric study.

Category: Equine - Osteoarthritis

BACKGROUND: Non-invasive imaging tools are needed to screen foal femoropatellar joints to detect subclinical osteochondrosis lesions due to focal failure of endochondral ossification to enhance early management to optimise intrinsic healing events. Recently investigations employing 3T susceptibility-weighted MRI (3T SWI MRI) and CT have demonstrated their capacity for early osteochondrosis diagnosis, but these technologies are not practical for field screening. We postulate that ultrasonography is a valuable field tool for the detection of subclinical osteochondrosis lesions.

REASONS FOR PERFORMING STUDY: Outcomes associated with arthrodesis of the proximal interphalangeal (PIP) joint in Quarter Horses used for Western performance activities are well documented but little is known regarding outcomes for other types of horses.

OBJECTIVES: To identify factors associated with outcomes, including breed and activity, after arthrodesis of the PIP joint in Warmbloods, Thoroughbreds and Quarter Horses.

STUDY DESIGN: Retrospective case series.

OBJECTIVES: To describe a technique for surgical placement of a modified kerf-cut cylinder for the purpose of arthrodesis across the equine centrodistal and tarsometatarsal joints.

OBJECTIVE: To describe an alternative technique and resulting outcomes for arthroscopic removal of osteochondral (OC) fragments from the proximal intertarsal joint (PIJ) using a direct approach without resection of the membrane between the tarsocrural joint (TCJ) and the PIJ.

STUDY DESIGN: Retrospective case series.

ANIMALS: Client owned horses (n = 11) with Category 1 OC fragments in the PIJ.

OBJECTIVE: To characterize discrete palmar carpal osteochondral fragmentation in horses and to document the effect of osteoarthritis and surgical removal of these fragments on functional outcome.

DESIGN: Retrospective case series.

ANIMALS: 25 horses.

Septic arthritis/tenosynovitis in the horse can have life-threatening consequences. The purpose of this cross-sectional retrospective study was to describe ultrasound characteristics of septic arthritis/tenosynovitis in a group of horses. Diagnosis of septic arthritis/tenosynovitis was based on historical and clinical findings as well as the results of the synovial fluid analysis and/or positive synovial culture.

Objective

To survey veterinary practitioners in Australia on how they administer pentosan polysulfate (PPS) to horses and their perceptions of the efficacy of PPS for: the prevention and treatment of osteoarthritis (OA), the treatment of OA when PPS is combined with other drugs, and the efficacy of PPS compared with other disease-modifying osteoarthritic drugs.
