PRACTICAL RELEVANCE: Traumatic stifle joint luxation is an uncommon but severe injury. There is usually rupture of several stabilising structures of the joint including the cruciate ligaments, collateral ligaments, joint capsule and menisci. Successful management of this condition requires good anatomical knowledge and repair or replacement of all damaged structures to achieve adequate joint reduction and stability. Better understanding of the treatment options available will aid clinical decision-making.

OBJECTIVE: To measure the density of cellular phenotypes in canine caudal cruciate ligament (CaCL), cranial cruciate ligament (CrCL), medial collateral ligament (MCL), and long digital extensor tendon (LDET).

STUDY DESIGN: Ex-vivo study.

METHODS: Ten CaCL, CrCL, MCL, and LDET obtained from 1 stifle of 10 dogs with no gross pathology were analyzed histologically. The density of cells with 3 nuclear phenotypes (fusiform, ovoid, and spheroid) was determined within the core region of each specimen.

OBJECTIVE: To evaluate recovery of limb function by use of gait force analysis after tibial plateau leveling osteotomy (TPLO) in dogs with unilateral cranial cruciate ligament (CrCL) rupture.

ANIMALS: 19 dogs with unilateral CrCL rupture treated with TPLO.

Measurement of fore and pelvic limb alignment in veterinary orthopedics is significant, as it is in human medicine. The establishment of reference ranges for alignments and comparing measured ranges in diseased animals to these reference values would allow veterinarians to specify the quantitative degree of an angular deformity, plan suitable treatments and evaluate treatment outcomes. Patellar luxation is a common orthopedic disease in small animal clinics.

OBJECTIVE: To compare use of a 3-level self-locking suture (3LSLS) technique with use of a previously described modified 3-loop pulley (M3LP) technique to repair rupture of the proximal aspect of patellar tendons in limbs from canine cadavers.

SAMPLE: Paired hind limbs of 6 adult mixed-breed dogs.

OBJECTIVE: The aim of this study was to determine the effect of the centre of rotation in tibial plateau levelling osteotomy (TPLO) on the tensile force of the quadriceps.

OBJECTIVE: To evaluate the effect of tibial plateau leveling osteotomy (TPLO) and tibial tuberosity transposition (TTA) on craniocaudal stability of the cranial cruciate ligament (CCL) deficient stifle at 3 joint angles.

STUDY DESIGN: Ex vivo biomechanical study.

A 12 yr old male neutered beagle was presented on transfer to the intensive care unit with severe anemia, thrombocytopenia, and bruising detected 1 day after undergoing tibial plateau leveling osteotomy surgery. The patient had undergone extra-capsular stifle stabilization surgery 14 wk prior to treat ligament disease in the same knee.

OBJECTIVE: Identify relevant electromyography (EMG), kinematic, and kinetic changes resulting from monopolar radiofrequency energy (MRFE)-induced cranial cruciate ligament (CCL) injury and eventual rupture in dogs.

STUDY DESIGN: Experimental, repeated measures.
