Objectives: To investigate the incidence of bilateral cranial cruciate ligament (CrCL) rupture and determine any associated risk factors. Methods: The patient information system and surgical database at the Queen Mother Hospital for Animals, Royal Veterinary College, were searched from March 1998 to March 2007. Patient files were reviewed and data recorded. The risk factors considered included: gender, neuter status, breed, body mass, age and concurrent orthopaedic disease. Results: In total, 511 dogs were identified as having cruciate rupture and included for analysis.

Objectives: To establish the effect of tibial plateau levelling osteotomy (TPLO) on two selected pelvic limb kinematic variables in dogs treated for clinical cranial cruciate ligament rupture (CCLR). Methods: Thirteen dogs that had incurred CCLR and were treated by TPLO walked on a treadmill whilst kinematic data on pelvic limb paw motion were acquired using motion capture equipment. Data were subject to secondary processing using matrix analysis software and statistical analysis.

OBJECTIVE:
To evaluate the effect of cold compression therapy (CCT) on postoperative pain, lameness, range of motion of the stifle joint, and swelling following tibial plateau leveling osteotomy (TPLO) in dogs.
DESIGN:
Randomized, blinded, placebo-controlled clinical trial.
ANIMALS:
34 client-owned dogs with unilateral deficiency of a cranial cruciate ligament undergoing TPLO.

OBJECTIVE:
To assess signalment, outcomes, and complications for dogs surgically treated for medial patellar luxation (MPL) with a combination of lateral retinacular imbrication and tibial crest transposition procedures without femoral trochlear groove deepening techniques, and to determine whether osteoarthritis progressed in these patients during the 8-week period following surgery.
DESIGN:
Retrospective case series. Animals-91 dogs.

The modified Maquet technique (MMT) uses the same principle as the tibial tuberosity advancement (TTA) for stabilization of the cranial cruciate ligament-deficient stifle in the dog. In the MMT, the tibial tuberosity is advanced in a similar manner to that used in the TTA, however the means by which the tibial crest is stabilized differs. The plate and fork originally described by Montavon et al. are not used (7).

Objective: To evaluate the effect of tibial tuberosity advancement (TTA) on cranial tibial thrust (CrTT), retropatellar force (RPF), patellar tendon load (PTL), and patellar tendon angle determined by the tibial plateau angle (PTA(TPA) ) method or common tangent (PTA(CT) ) method in the canine cranial cruciate ligament (CrCL)-deficient stifle joint. Study Design: Ex vivo cadaver study. Sample Population: Cadaveric canine hind limbs (n=30).

Objectives: To determine the combination of conformation characteristics of the pelvic limbs of Labrador Retrievers that best discriminates between limb at risk to develop cranial cruciate ligament (CCL) disease and limbs at low risk using radiographs, computerized tomography (CT) images, and dual-energy X-ray absorptiometry (DEXA). Study Design: Cross-sectional clinical study. Animals: Twelve clinically normal and 9 unilaterally CCL-deficient Labrador Retrievers.

Objective: Mechanical evaluation of 2 suture constructs for extracapsular stifle stabilization. Study Design: In vitro study. Sample Population: Crimped interlocking loop constructs (ILC) of 45 kg nylon leader line (NLL) and Orthofiber(®) (OF). Methods: ILC were tightened to 100 N, then crimp secured. Ramp to failure (n=10/group)-Data were derived from force/displacement plots. Stress-relaxation testing (n=10/group)-ILC's were nondestructively loaded and held at resultant displacement as force data were recorded.

A seven-year-old Labrador Retriever dog was presented with the complaint of chronic left hindlimb lameness. A diagnosis of partial rupture of the left cranial cruciate ligament with concurrent cranio-medial synovial cyst formation was made. This cystic structure was assumed to be communicating with the stifle joint. There was no evidence of a meniscal tear, but superficial fibrillation of the axial border was present. Surgical excision of the cyst with concurrent treatment of the cranial cruciate ligament deficiency by tibial tuberosity advancement was performed with a successful outcome.

Cranial cruciate ligament disease (CCLD) is the most common cause of hindlimb lameness in the dog, being associated with and eventually leading to stifle osteoarthritis. Canine cranial cruciate ligament disease is a gradual degeneration of the ligament extracellular matrix (ECM) leading to ligament rupture. The aetiopathogenesis of this condition is still poorly understood but several risk factors have been identified such as breed, bodyweight, gender and conformation.
