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.
Tendon and Ligament Injuries
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.
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 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.
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.
PURPOSE: To investigate whether magnetic field-related anisotropies of collagen may be correlated with postmortem findings in animal models.
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).
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.
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 compare the biomechanical properties of four different methods of artificial cranial cruciate ligament fixation in canine cadaveric tibias and femurs.
