BACKGROUND: Patellar abnormalities are a common cause of pain and lameness in dogs; however, in vivo the relative motion between the femur and patella in dogs is not well described. The objective of this study was to define normal in vivo sagittal plane patellofemoral kinematics in three axes of motion using non-invasive methods. We hypothesized patellofemoral alignment in the sagittal plane would tightly correlate with the femorotibial flexion angle.
OBJECTIVE: To report the surgical procedure, intra- and postoperative complications, and short-term follow-up of tibial plateau levelling osteotomy (TPLO) in feline patients with cranial cruciate ligament (CrCL) rupture using a 2.0 or 2.4 mm Synthes® TPLO plate.
STUDY DESIGN: Prospective study.
OBJECTIVE: Evaluate the short-term outcomes of a novel synthetic ligament for treatment of naturally occurring canine cranial cruciate ligament disease.
STUDY DESIGN: Prospective clinical study.
ANIMALS: Dogs with unilateral cranial cruciate ligament disease (n = 50).METHODS:
Patient parameters evaluated included a five-point lameness score, evaluation of craniocaudal stifle instability, and radiographic findings over 24 weeks. Any postoperative complications were recorded.
OBJECTIVES: The aim of the study was to evaluate the prevalence, size, location and appearance of mineralisations in feline stifle joints, and to evaluate their relationship with osteoarthritis and cranial cruciate ligament (CrCL) status.
OBJECTIVE: To describe the outcome of cranial closing wedge osteotomy (CWO) of the tibia for treatment of cranial cruciate ligament (CrCL)-deficient stifles in dogs with a body weight of <15 kg.
STUDY DESIGN: Retrospective case series.
ANIMALS: Forty-five client-owned dogs (n=55 stifles).
METHODS: Medical records (2005-2014), radiographs, and owner questionnaire were used to identify the surgical procedure performed, associated complications and outcome in 45 dogs undergoing CWO in 55 stifles.
OBJECTIVE: To assess complication rates and short-term outcome in small dogs with bilateral medial patellar luxation (MPL) undergoing single-session bilateral corrective surgery.
STUDY DESIGN: Retrospective case series.
ANIMALS: Dogs weighing <15 kg with congenital bilateral MPL that underwent single-session bilateral corrective surgery (n = 50).
OBJECTIVE: To evaluate the usefulness of laser Doppler flowmetry (LDF) to measure surface blood flow in canine cruciate ligaments, compare measurements in different sites of intact and partially ruptured canine cranial cruciate ligaments (CrCL) and intact caudal cruciate ligaments (CaCL), and investigate any association between surface blood flow in partially ruptured CrCL and synovitis or duration of clinical signs.
STUDY DESIGN: Case-controlled clinical study.
ANIMALS: Sixteen dogs with partially ruptured CrCL and five dogs with intact CrCL.
Distal femoral osteotomy is a surgical procedure used to correct patellar luxation, secondary to a femoral deformity. A distal femoral osteotomy using the tibial plateau levelling osteotomy-jig to temporarily provide stability of the distal femoral osteotomy, maintaining limb alignment in the frontal and axial planes prior to internal plate fixation of the osteotomy, has been described.
The literature about tibial tuberosity advancement surgery in dogs and humans informed the development of a version of the operation using a wedge-shaped implant of titanium foam. Computer-assisted drawing and stereolithography was used to create instruments and implants that were evaluated by cadaver surgery. A trial, involving 26 client-owned dogs with lameness due to cranial cruciate ligament failure, was started. Follow-up was done by clinical and radiographic examination after 4 wk and clinical examination again 6-11 mo after surgery.
The aim of this blinded, randomised, prospective clinical trial was to determine whether the addition of magnesium sulphate to spinally-administered ropivacaine would improve peri-operative analgesia without impairing motor function in dogs undergoing orthopaedic surgery.
