OBJECTIVE: To describe clinical signs, arthroscopic findings, and outcome in a group of dogs undergoing second look arthroscopy for the treatment of meniscal tears following original surgery to correct a CCL deficient stifle joint. METHODS: The medical records of 26 dogs from the Veterinary Teaching Hospital at Texas A&M University and the Veterinary Orthopedic Center (Round Rock, Texas) that had second look arthroscopy for lameness following an original surgical procedure were reviewed.

The purpose of this study was to evaluate the ability of proximal tibial epiphysiodesis to reduce the tibial plateau slope in young dogs with cranial cruciale ligament (CCL) deficient stifles. Of the 14 treated dogs, eight had a bilateral injury, for a total of 22 joints. After physical and radiographical examination and measurement of tibial plateau slope, all of the dogs underwent surgery.

OBJECTIVES: To evaluate the high incidence of tibial tuberosity avulsion fracture diagnosed in skeletally immature Staffordshire bull terriers presenting to a UK animal welfare charity hospital. METHODS: A retrospective review of tibial tuberosity avulsion fractures treated by the hospital between 2002 and 2007. RESULTS: Sixty-five tibial tuberosity avulsion fractures were recorded in 59 dogs. Fifty-one tibial tuberosity avulsion fracture-affected dogs (86 per cent) were Staffordshire bull terriers.

Objective: To describe the perioperative complications and the six weeks and eight to 12 months outcome of cases of canine cranial cruciate ligament damage treated with a tibial tuberosity advancement. Methods: The medical records including the six weeks' postoperative re-evaluation and radiographs of dogs with a tibial tuberosity advancement (70 operated stifles) were analysed regarding the short-term outcome and the recorded complications. A questionnaire for the evaluation of the eight to 12 months outcome was sent to the owners and the answers tabulated.

OBJECTIVE: To design and manufacture custom titanium bone plates and a custom cutting and drill guide by use of free-form fabrication methods and to compare variables and mechanical properties of 2 canine tibial plateau leveling methods with each other and with historical control values. SAMPLE POPULATION: 10 canine tibial replicas created by rapid prototyping methods.

An in vitro experimental cadaveric mechanical testing study was performed using 20 radiographically mature dogs, weighing between 18-33 kg. The aim of the study was to compare the axial pull-out strength of 3.5 mm cortical and 4.0 mm cancellous bone screws inserted in the canine proximal tibia using manual and power tapping techniques. 3.5 cortical and 4.0 cancellous bone screws were inserted in canine cadaver proximal tibiae using a manual or power tapping technique. The screws were extracted using a servohydraulic materials testing machine in order to measure axial pull-out strength.

OBJECTIVE: To develop and assess clinical outcomes for osteochondral autografting for treatment of stifle osteochondrosis (OC) in dogs. STUDY DESIGN: Retrospective case series. ANIMALS: Dogs with stifle OC (n=10). METHODS: Osteochondral autografting was developed and optimized in canine cadavers and purpose-bred research dogs using the Osteochondral Autograft Transfer System (OATS). Dogs with stifle OC (n=10 dogs, 12 stifles) were then treated using the OATS system.

OBJECTIVE: To evaluate factors that predispose to tibial tuberosity (TT) fracture after tibial plateau leveling osteotomy (TPLO) in dogs. STUDY DESIGN: Retrospective study. ANIMALS: Dogs (n=182) with cranial cruciate ligament (CCL) rupture undergoing 213 TPLO surgeries. METHODS: Medical records and radiographs of 2 groups of dogs that had TPLO surgery (2000-2001, 2004-2005) were evaluated to determine the effect of operative technique and surgeon experience on TT fracture. RESULTS: TT fracture was diagnosed in 8 dogs (9 TPLO, 4.2% of surgical procedures).

OBJECTIVE: To compare tibial plateau rotation after tibial plateau leveling osteotomy with the radiographically planned rotation and to determine the effect of translations and rotations of the tibial plateau fragment on the biomechanical stability of the construct under cyclic loading. STUDY DESIGN: Experimental biomechanical study. ANIMALS: Cadaveric canine pelvic limbs (n=10). METHODS: Titanium pins were inserted into the tibial plateau and the proximal metaphysis to track the fragment movements by means of computed tomography (CT) imaging.
