The Effect of Gap Formation at the Repair Site on the Strength and Excursion of Intrasynovial Flexor Tendons. AN EXPERIMENTAL STUDY ON THE EARLY STAGES OF TENDON-HEALING IN DOGS*

Rotator Cuff Repair Augmentation in a Canine Model with Use of a Woven Poly-L-Lactide Device

“…The relevance of this outcome is made manifest by the significant relationship found between tendon retraction distance and both stiffness and ultimate load-that is, the repairs that retracted less had higher stiffness and higher ultimate load. A similar, inverse correlation between retraction distance and repair strength and stiffness has been shown in healing flexor tendon repair 60,61 . Together, these data emphasize that achieving less retraction by way of device augmentation translates into a stiffer and stronger tendon repair.…”

Tendon surface modification by chemically modified HA coating after flexor digitorum profundus tendon repair

“…35 Under an active postoperative therapy, the force applied to the tendon is much greater than this increased frictional force, but the risk of rupture is significant. 36,37 Recent studies of friction within the entire sheath have confirmed that the total system friction is considerably higher than that measured against the A2 pulley alone, underlining the importance of strategies to control friction during tendon rehabilitation. 38 Recent experiments have also shown that greater friction results in poorer gliding and more adhesions in vivo in this dog model, 39 as would be predicted based on the in vitro data.…”

The past, present and future in scaffold-based tendon treatments

“…Multi-strand (primarily four-strand [328]) locking configuration are extensively used in clinical practice. Although locking loops prevent sutures from pulling, they are often associated with suture breakage and tendon rupture due to pulling of the suture at the sutured site [329]. Given that knots adversely affect gliding and locking configurations negatively impact on vascularity, barbed sutures have gained more attention as they ensure equal distribution of load throughout the intratendinous suture length [330][331][332][333][334].…”
