Abstract:
Feline Osteoarthritis (OA) is a pathological change of a diarthrodial articulation which primarily occurs in older cats. The aims of this study were:- 1) to define the radiographic features of OA in the cat for each individual appendicular joint; 2) to relate the radiographic features to the gross pathologic and histopathologic features; 3) to explore underlying causes of OA in cats, 4) to identify the presence of Protease Activated Receptor-2 (PAR-2) and matriptase in feline articular cartilage and synovial membrane and to determine their role in OA pathogenesis.

Abstract:
Every year, about 1 million patients worldwide and 16000 patients in Sweden undergo total hip arthroplasty (THA). This surgical intervention is considered a successful, safe and cost-effective procedure to regain pain-free mobility and restore hip joint function in patients suffering from severe hip joint disease or trauma. Besides relieving the pain, restoration of biomechanical forces around the hip with appropriate femoral offset (FO), leg length and proper component position and orientation are important goals.

Abstract:
The tarsus is one of the most vital equine articulations. It is a complex joint which absorbs concussion from ground contact and translates force for locomotion from the upper limb. Diseases of the equine tarsus are commonly seen by veterinary practitioners and are frequently responsible for lameness leading to functional and economic loss. A radiographic examination is generally required to determine the precise pathological processes involving the tarsus (Kovacs 1963).
