Tendon and Ligament Injuries

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.

The medical records of cats receiving surgical treatment for unilateral patellar ligament rupture between 1999 and 2012 at 12 referral centres in the UK and Ireland were reviewed. Seven cases were identified: six were caused by trauma and one was iatrogenic, occurring as a complication following surgical stabilisation of a tibial fracture.

OBJECTIVE: To (1) describe a modified technique for tibial tuberosity advancement (TTA) in dogs with cranial cruciate ligament (CCL) rupture and (2) report short term outcome and complications.

STUDY DESIGN: Prospective clinical study.

ANIMALS: Dogs with unilateral CCL rupture (n = 50).

METHODS: TTA was performed with a novel implant to achieve advancement of the tibial crest. The technical protocol, specific implants and instrumentation, and the short term outcome are described.

OBJECTIVE: To evaluate factors related to meniscal pathology and their effect on clinical outcome in dogs treated for cranial cruciate ligament (CCL) disease.

STUDY DESIGN: Prospective cross-sectional study.

ANIMALS: Dogs (n = 163) with CCL disease (n = 223 stifles).
