Introduction: Patellar ligament thickening is a recognized response following osteotomy of the proximal tibia as a treatment for cranial cruciate disease. In humans this is seen as a response to increased loading, but the reason for this thickening in dogs is unclear. A prospective study was undertaken to assess the degree and frequency of patellar ligament desmopathy in 25 consecutive cases undergoing tibial tuberosity advancement (TTA). Objectives: To determine the incidence of patellar ligament thickening following TTA.

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.

Objective: To report the signalment and clinical features of dogs with non-traumatic lateral patellar luxation and to report the complications and outcomes following surgery. Methods: A multicentre retrospective study was performed. Medical records were reviewed and the signalment, clinical features, and treatment of dogs presenting with lateral patellar luxation were recorded. In dogs treated surgically, the outcome and complications were investigated. Results: Sixty-five dogs (95 stifles) were included; 39 were male and median age at presentation was 10 months.

This retrospective study identified complications associated with tibial plateau leveling osteotomy (TPLO) and predisposing factors for these complications in a large population of dogs from a metropolitan area with cruciate ligament deficiency. There were 943 dogs that underwent unilateral TPLO and 288 with staged bilateral TPLO for a total of 1519 procedures. There were 47 cases with at least 1 major complication and 126 cases with at least 1 minor complication but no major complications.

Objective-To determine whether carpal brace application is a viable treatment for dogs with unilateral carpal ligament instability. Design-Retrospective case series. Animals-14 client-owned athletic dogs. Procedures-Medical records were reviewed to identify dogs treated with abrace for unilateral carpal valgus or varus instability between August 2008 and August 2011. Treatment included passive motion and isometric strengthening exercises during brace application. Results-Of the 14 dogs, 11 were considered to have returned to normal function; 11 of 12 dogs returned to agility competition.
