“…Some authors have suggested that increased contact pressures may compromise tendon vascularity. Maguire et al 25 found that the TOE-SB without medial knots did not demonstrate inferior failure load, tendon-bone contact area, or gapping characteristics compared with knotted medial row constructs in cadaveric specimens. 3 Clinical studies directly testing this hypothesis are lacking.…”

“…2) For this reason, the rat has been the most commonly used animal model in rotator cuff research, with more than 100 full-length, peer-reviewed publications to date. Nevertheless, a variety of other valuable animal models also continue to be used to replicate aspects of rotator cuff injury and repair, including murine, 26-28 rabbit, 29,30 ovine, 31-37 canine, 38,39 bovine, 40-43 and primate. 44,45 …”

“…Studies in this area often use in vitro ovine or bovine models, and focus on surgical variables during repair such as type of suture material 41 ; number of sutures or rows of suture 29,32-39,42 ; type of knot 36,37,42 and type and/or number of anchors 37,42,43 used in the repair. Several of these studies indicate that knot slipping may be the cause of repair failures, as this phenomenon occurs at substantially lower loads than anchor pull-out.…”

Tendinopathy is a debilitating musculoskeletal condition which can cause significant pain and lead to complete rupture of the tendon, which often requires surgical repair. Due in part to the large spectrum of tendon pathologies, these disorders continue to be a clinical challenge. Animal models are often used in this field of research as they offer an attractive framework to examine the cascade of processes that occur throughout both tendon pathology and repair. This review discusses the structural, mechanical, and biological changes that occur throughout tendon pathology in animal models, as well as strategies for the improvement of tendon healing.Cite this article: Bone Joint Res 2014;3:193–202.

“…The authors reported that modification with the double mattress technique has significantly better biomechanical construct stability and higher resistance to suture cutting through the repaired tendon. Maguire et al [37] also evaluated the biomechanical properties of four variants of the suture bridge repair via modifications of medial row stitches (i.e. knotted standard suture bridge, knotted double suture bridge, untied suture bridge with medial anchor screw, and untied suture bridge with PushLock screw (Arthrex)).…”

Rotator cuff tears are one of the most common disorders of the shoulder and can have significant effects on daily activities as a result of pain, loss of motion and strength. The goal of rotator cuff repair is aimed at anatomic restoration of the rotator cuff tendon to reduce pain and improve the joint function. Recently, arthroscopic repair has been widely accepted for treatment of rotator cuff tears due to its equal or better results than those from open repair. In 2006, a transosseousequivalent (TOE) or "suture bridge" technique was introduced by Park et al. This technique maximizes the utility of the conventional double-row technique by using the suture limbs to form the media mattress sutures to bridge and compress the repaired tendon. This technique has been proven to provide biomechanical properties that are superior to other arthroscopic repair techniques regarding the initial fixation strength, contact area and contact pressure at the tendon-bone interface. Since suture bridge techniques have been evolving over time, further biomechanical investigations have been carried out. These studies include examination of the effects of dynamic humeral external rotation on the mechanic stability of the repaired tendon construct, the effects of various modifications of the suture bridge configurations on the biomechanical characteristics of the medial mattress suture, biomechanical implications of medial row failure, and biomechanical performance of the repaired constructs over time. In this review, the biomechanical concepts behind the suture bridge technique for rotator cuff repair were reviewed and discussed.
