Tendon and Ligament Injuries

This is a retrospective study evaluating femoral-sciatic nerve blocks (FSBs), epidural analgesia, and non-regional analgesia (NRA) in dogs undergoing tibia-plateau-leveling-osteotomy surgery.

OBJECTIVE: To compare the ability of the Tightrope® (TR) cranial cruciate ligament (CCL) technique, percutaneous lateral fabella suture (pLFS) technique, and normal CCL to control cranial tibial translation (CTT).

STUDY DESIGN: In vitro biomechanical study.

OBJECTIVE: To report successful surgical repair of a grade IV lateral patellar luxation in a 437-kg heifer.

STUDY DESIGN: Case report.

ANIMAL: Seventeen-month-old Holstein heifer (437 kg).

METHODS: Diagnosis of traumatic lateral patellar luxation was made based on physical examination, and confirmed on radiographs. Arthroscopic examination of the stifle assessed joint changes. Lateral patellar luxation was surgically repaired using lateral release of the patella and medial imbrication of the joint capsule.

OBJECTIVE: To describe a novel technique utilizing the flexor digitorum lateralis tendon to repair rupture of the common calcaneal tendon with a gap defect.

OBJECTIVE:  To compare the peak vertical force (PVF) and vertical impulse (VI) in dogs with naturally occurring cranial cruciate ligament (CCL) disease with or without concurrent meniscal injury.

OBJECTIVES: Chronic degeneration of the gastrocnemius tendon results in scar tissue formation at the insertion of the tendon, and detachment from the calcaneus. In severe cases, excision of this tissue makes repositioning of the tendon to the calcaneus extremely difficult. A polyethylene terephthalate implant, used to aide repair by bridging gaps and allowing tissue ingrowth, was evaluated.

OBJECTIVE: To estimate the prevalence and risk factors for a diagnosis of cranial cruciate ligament (CCL) disease in dogs and to describe the management of such cases attending primary-care veterinary practices.

STUDY DESIGN: Historical cohort with a nested case-control study.

SAMPLE POPULATION: Nine hundred and fifty-three dogs diagnosed with CCL disease from 171,522 dogs attending 97 primary-care practices in England.

Current research indicates that exogenous stem cells may accelerate reparative processes in joint disease but, no previous studies have evaluated whether bone marrow cells (BMCs) target the injured cranial cruciate ligament (CCL) in dogs. The objective of this study was to investigate engraftment of BMCs following intra-articular injection in dogs with spontaneous CCL injury. Autologous PKH26-labelled BMCs were injected into the stifle joint of eight client-owned dogs with CCL rupture.

OBJECTIVE: To analyse the best combination of isometric points with the best kinematic results between two different approaches of TightRope® cranial cruciate ligament reconstruction.

MATERIALS AND METHODS: Cranial drawer, cranial tibial thrust, internal/external, range of motion and varus/valgus tests were passively performed in different stifle conditions: cranial cruciate ligament-intact/deficient, after F2-T2/F2-T3 TR reconstruction at 22-44-99 N of tension. Data were acquired by a custom-made navigation system.

Avulsion of the triceps tendon insertion was diagnosed in a two-year-old Poodle mixed breed dog 10 weeks after traumatic injury. Diagnosis was confirmed with clinical examination and magnetic resonance imaging (MRI).

The tendon was reconstructed using tension-relieving sutures augmented with a synthetic degradable porous polyurethane urea onlay mesh graft. The repair was immobilized using a transarticular external skeletal fixator with staged increases in elbow flexion.
