Objective: To compare the biomechanical properties and gapping characteristics of four novel tenorrhaphy patterns in a canine flexor tendon model.

Study design: Ex vivo, randomized, biomechanical study.

Sample population: Superficial digital flexor tendons of 60 forelimbs (30 dogs).

Objective: The purpose of this clinical communication is to report the management of common calcaneal tendon rupture in dogs using a transarticular calcaneo-tibial locking plate as a method of temporary immobilization of the tarsocrural joint to support primary repair of the common calcaneal tendon.

Authors: Daniel J Duffy, Yi-Jen Chang, Matthew B Fisher, George E Moore

Objective: To determine the effect of a novel barbed suture pattern (NBSP) compared to a three-loop-pulley (3LP) with and without epitendinous suture (ES) augmentation on the biomechanical strength and gap formation of repaired canine tendons.

Study design: Ex vivo, cadaveric, randomized, experimental study.

Sample population: Forty, adult superficial digital flexor tendons (SDFT).

Authors: Daniel J Duffy, Yi-Jen Chang, Matthew B Fisher, George E Moore

Objective To evaluate the effect of accessory tendon graft (ATG) augmentation as an adjunct to a core locking‐loop (LL) and epitendinous suture (ES) repair in a gastrocnemius tendon (GT) model.

Study Design Randomized, ex vivo, biomechanical.

Authors: Feng Wei, Tammy Haut Donahue, Roger C Haut, Maria Dolores Porcel Sanchez, Loic M Dejardin

Objective: To clarify and improve a cranial cruciate ligament (CrCL) deficient stifle stabilization technique using a semitendinosus tendon (ST) autograft fixed with an interference fit screw (IFS) in a closed-joint trauma lapine osteoarthritis (OA) model.

Study design: Experimental OA model.

Animals: Forty-one Flemish Giant rabbits.

Authors: Jaemin Jeong, Seong Mok Jeong, Stanley E Kim, Daniel D Lewis, Haebeom Lee

Objective: To evaluate the short- and mid-term effects of tibial tuberosity advancement (TTA) and tibial plateau leveling osteotomy (TPLO) on subsequent meniscal tears.

Study design: Experimental in vivo study.

Animals: Purpose-bred beagle dogs (n = 15).

Authors: Karolina S Engdahl, Gudrun S Boge, Annika F Bergström, Elena R Moldal, Odd V Höglund

Objective: To analyze the effect of surgical technique and other risk factors on severe postoperative complications in dogs with cranial cruciate ligament disease (CCLD).

Authors: Daniel J Duffy, Yi-Jen Chang, Lewis Gaffney, Matthew B Fisher, George E Moore

Objective: To evaluate the effect of a continuous locking novel epitendinous suture (nES) pattern with and without a core locking-loop (LL) suture on the biomechanical properties of ex vivo canine superficial digital flexor tendon (SDFT) tenorrhaphy constructs.

Sample: 54 cadaveric forelimb SDFTs from 27 musculoskeletally normal adult dogs.

Authors: Keiichi Kuroki, Ned Williams, James L Cook

Objective: To investigate histopathological features of synovium from dogs with cranial cruciate ligament disease (CCLD) to seek mechanisms of osteoarthritis (OA) associated with CCLD.

Study design: Retrospective, single-institution case series.

Animals: Thirty client-owned dogs.
