Effect of a poloxamer-based thermosensitive gel on rotator cuff repair in a rabbit model: a controlled laboratory study
Authors: Kim TI, Jung W, Chung JY, Jeong H, Kim SH

BACKGROUND: A common complication after rotator cuff repair is postoperative stiffness, which can be reduced by a simple application of an anti-adhesive agent. However, anti-adhesive agents may affect rotator cuff healing by preventing fibrosis. This experimental animal study evaluated the effect of the application of a poloxamer-based thermosensitive anti-adhesive gel and its influence on the healing of an acute rotator cuff repair in a rabbit model.

Proinflammatory polarization of stifle synovial macrophages in dogs with cruciate ligament rupture
Authors: Yarnall BW, Chamberlain CS, Hao Z, Muir P

OBJECTIVE: To determine polarization of synovial macrophages during development of cruciate ligament rupture (CR) and determine whether differences in synovial macrophage polarization in CR, osteoarthritis (OA), and healthy joints exist.

STUDY DESIGN: Prospective case-controlled study.

ANIMALS: Client-owned dogs with unstable stifles with CR (n = 22), paired stable contralateral stifles with partial CR (pCR; n = 7), joints with OA not related to CR (n = 6), and clinically normal (Normal; n = 7) joints.

Effect of a continuous epitendinous suture as adjunct to three-loop pulley and locking-loop patterns for flexor tendon repair in a canine model
Authors: Putterman AB, Duffy DJ, Kersh ME, Rahman H, Moore GE.

OBJECTIVE: To evaluate the effect of combining a continuous epitendinous suture with three-loop pulley (3LP) and locking-loop (LL) core patterns for flexor tendon repair.

STUDY DESIGN: Ex vivo biomechanical study.

SAMPLE POPULATION: Seventy-two cadaveric superficial digital flexor musculotendon (SDFT) units.

Ligament Laxity in Nonerosive Immune-Mediated Polyarthritis in Dogs: Five Cases (2009-2017)
Authors: Whitworth F, Adamantos S, Frowde P, Whitelock R, Black VL

Ligament laxity is a known complication of erosive immune-mediated polyarthritis (IMPA) in dogs. The purpose of this study was to describe the occurrence and clinical features of carpal or tarsal ligament laxity in cases of nonerosive IMPA in dogs for the first time.

Biomechanical comparison of three epitendinous suture patterns as adjuncts to a core locking loop suture for repair of canine flexor tendon injuries
Authors: Cocca CJ, Duffy DJ, Kersh ME, Kim W, Groenewold A, Moore GE

OBJECTIVE: To determine the effects of different epitendinous sutures (ES) in addition to core locking-loop (LL) sutures on the mechanical properties and gap formation in a canine cadaveric tendon model.

STUDY DESIGN: Experimental, ex vivo, biomechanical study.

Biomechanical comparison of four prosthetic ligament repair techniques for tarsal medial collateral ligament injury in dogs
Authors: Martin Y, Johnson MD, Travers CJ, Colee J, McConkey MJ, Banks SA.

OBJECTIVE: To compare joint stability and ultimate strength among 4 prosthetic ligament constructs for repair of tarsal medial collateral ligament (MCL) injury in dogs.

SAMPLE: 13 canine cadavers (26 hind limbs).

Authors: Amimoto H, Koreeda T, Wada N.

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.

Biomechanical comparison of a modified three-loop pulley technique and a three-level self-locking technique for repair of patellar tendon rupture in dogs
Authors: Soula M, Shmalberg JW, Johnson MD.

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.
