OBJECTIVE To compare biomechanical strength of 4.75- and 5.5-mm suture anchors when pulled at 45° or 90° angles using 1 versus 2 strands of suture.

SAMPLE 48 synthetic bone block samples.

PROCEDURES Anchors were inserted into synthetic bone blocks and tested for pullout in 4 configurations (1 suture strand vs 2 strands and 45° vs 90° insertion angle) for a total of 8 groups with 6 samples each. A 3-way ANOVA was used to compare effect of anchor size, strand amount, and angle of pull.

Objective: To use the small data approach of the Clinical and Laboratory Standards Institute (CLSI) to evaluate the transferability of reference intervals (RIs) for kinetic variables obtained with instrumented gait analysis (IGA) in dogs from an RI-originator laboratory to another laboratory that used the same data acquisition and analytic techniques for IGA in walking dogs.

Animals: 27 adult client-owned dogs without evidence of lameness.

Objective: To evaluate the effect of an autologous flexor digitorum lateralis (FDL) graft to augment a three-loop pulley (3LP) core repair in a canine cadaveric gastrocnemius tendon (GT) laceration model.

Study design: Ex vivo, biomechanical study.

Sample population: Twenty-six canine cadaveric hind limbs.
