ABSTRACT
Objective—To compare biomechanical properties of 3 new generation polyethylene sutures (FiberTape [FT], FiberWire [FW], and OrthoFiber [OF]) with nylon leader line (NL) for use during extraarticular fixation of cranial cruciate deficient stifles.
Study Design—In vitro biomechanical testing of suture loops under monotonic tensile and cyclical loading until failure.
Sample Population—Constructs of FT, FW, OF, and NL.

Our study evaluated thigh circumference (TC), stifle range of motion (ROM), and lameness in dogs one to five years after unilateral tibial plateau levelling osteotomy (TPLO). We hypothesised that TC, stifle ROM, and lameness would not be different to the unoperated limb (control), one to five years after surgery. Patients that were one to five years post-TPLO were reviewed and were included if they had a unilateral TPLO, and no additional clinical evidence of orthopaedic disease. Standing mid-thigh TC measurements and stifle extension and flexion angles were made in triplicate.

OBJECTIVES: To evaluate a novel surgery aimed at managing concurrent medial patellar luxation (MPL) and cranial cruciate ligament (CCL) ruptures in dogs weighing more than 30 kg. METHODS: Tibial plateau levelling osteotomy (TPLO) and femoral trochleopasty were performed. The principal tibial fragment was laterally translated by 3 to 6 mm and was externally and abaxially rotated to create a wedge measuring 1.5 to 2.5 mm at the medial and cranial aspect and 1 to 3 mm at the medial and distal aspect of the tibial plateau fragment. The fragments were stabilised with a narrow TPLO plate.

ABSTRACT
Objective—To compare the effects of hydrogen peroxide gas plasma (HPGP) and ethylene oxide (EO) sterilizations on the mechanical properties of nylon lines used for stabilization of the canine stifle. Secondarily, to compare the performance of crimped and knotted lines.
Study Design—In vitro mechanical evaluation.
Sample Population—Nonsterilized, EO- and HPGP-sterilized specimens of 36.3 kg test nylon leader line (NLL) and 57.8 kg test nylon fishing line (NFL).

Objective-To evaluate the incidence of and potential risk factors associated with development of postoperative infection-inflammation in a large number of dogs with rupture of the cranial cruciate ligament (CCL) that were treated via elective surgery. Design-Retrospective case series. Animals-808 dogs that underwent surgery (902 procedures) for rupture of the CCL. Procedures-Medical records of dogs that underwent extracapsular lateral suture (ECLS) stabilization or tibial plateau leveling osteotomy (TPLO) between January 1, 2005, and December 31, 2006, were reviewed.

This prospective study used radiographic techniques to evaluate the inclination, Norberg, quadriceps and femoral varus angles, and the patellar position in dogs with developmental medial patellar luxation. The study also compared these measurements pre- and post-operatively to determine how they were affected by surgical procedures. Eighteen dogs with unilateral or bilateral luxation were used, and 4 groups were established according to luxation grade. Except for the quadriceps angle, there was no difference among the groups preoperatively.

OBJECTIVE: To evaluate use of a transcondylar toggle system (TCTS) for stabilization of the cranial cruciate ligament (CrCL) deficient stifle in small dogs and cats. STUDY DESIGN: Prospective clinical study. ANIMALS: Small dogs (<7 kg; n=14) and cats (2) with CrCL-associated lameness of <3 months duration and a tibial plateau angle <32 degrees. METHODS: Affected animals had an extracapsular CrCL repair using the TCTS. Lameness score, muscle atrophy, osteoarthritis (OA) score, and range of motion (ROM) were evaluated preoperatively, and at 6 weeks and 7-10 months postoperatively.
