Authors: King Wa Chiu, Daniel J Duffy, Yi-Jen Chang, Lewis Gaffney, Matthew B Fisher

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.

Authors: Chiara P Curcillo, Daniel J Duffy, Yi-Jen Chang, George E Moore

Objective: This study aimed to evaluate the effect of increasing the number of suture strands traversing the transection site, level of suture purchase and depth of suture penetrance on the biomechanical properties of repaired gastrocnemius tendons.
