Abstract
Objective: To assess the biomechanical properties and failure mode of 3 different repair methods in simulated midsubstance canine patella ligament rupture on cadavers.
Methods: The sample was paired hindlimbs of 9 adult mixed-breed dogs. The study design was an experimental study on cadavers. Patellar ligaments were transected and sutured using a Bunnell and simple interrupted epitendinous pattern. They were then randomly reinforced with 1 of 3 techniques: a circumpatellar suture loop anchored distally to the tibial tuberosity (group 1), the same loop combined with a fascia lata strip (group 2), or a polyethylene synthetic implant sutured over the patella proximally and secured distally with an interference screw (group 3). Yield, peak, and failure load, stiffness, and mode of failure were evaluated.
Results: Six hindlimbs were assigned to each group. Augmentation with the synthetic implant (group 3) showed significantly greater yield, peak, and failure load than group 1. There were no significant differences between group 2 and either group 1 or group 3.
Conclusions: Patellar ligament repair augmented with a synthetic ultrahigh-molecular-weight polyethylene implant offered greater tensile strength than a Bunnell suture with an adjunction of a circumpatellar repair.
Clinical relevance: The use of a synthetic ultrahigh-molecular-weight polyethylene implant may offer a viable surgical option for patellar ligament repair. Further studies are warranted to assess the long-term outcome in vivo in patients with injured patellar ligament.
期刊介绍:
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
