To determine whether the addition of recombinant human bone morphogenetic protein (rhBMP-2) to a self-crosslinkable cellulosic hydrogel/biphasic calcium phosphate (BCP) granules construct promotes bone healing in critical-size ulnar defects in dogs.

A four-year-old, male Cocker Spaniel was presented for investigation of pelvic limb stiffness. There was palpable effusion of both tarsi, and analysis of synovial fluid from these joints indicated previous haemorrhage. After further investigation a diagnosis of idiopathic immune-mediated thrombocytopenia was made. The dog responded to treatment with prednisolone and azathioprine. To the authors' knowledge, this is the first reported case of confirmed haemarthrosis as the sole presenting clinical sign for canine idiopathic immune-mediated thrombocytopenia.

To evaluate the economic impact of surgical site infection after tibial plateau leveling osteotomy (TPLO) in dogs.


Retrospective study


Dogs that had unilateral TPLO and did (n = 32) or did not (controls; 32) develop a surgical site infection.


Medical and billing records were reviewed to identify postoperative care and costs, which were compared between groups.

Objectives: To measure the activity of matrix metalloproteinases (MMP)-2 and -9 in synovial fluid from the stifle joints of dogs with cranial cruciate ligament (CrCL) rupture and to compare that to values from contralateral stifle joints and dogs with clinically normal stifle joints. Additionally, the C-reactive protein (CRP) levels were also measured. Methods: Fourteen large breed dogs with unilateral CrCL rupture and 11 large breed normal dogs were included in this prospective clinical study.

Objective: The aim of this study was to track the survival and efficacy of allogeneic bone marrow mesenchymal stem cells (BM-MSC) marked with red fluorescent protein (BM-MSCRFP) in an ovine model of collagenase-induced tendinopathy. Methods: Bone marrow was harvested from one donor sheep and BM-MSC were isolated, cultivated and transfected with red fluorescent protein (BM-MSCRFP). Collagenase was injected into both Achilles tendons in the remaining nine sheep.
