Abrasiveness of high-strength sutures used in rotator cuff surgery: are they all the same?

Background: The suture-tendon interface remains the most common point of failure in rotator cuff repairs via suture pullout. Several high-strength braided sutures are available for rotator cuff surgery and are more abrasive than monofilaments. However, a comparison of these sutures has not been performed in a tissue model.

Biomechanical Analysis of Screws Versus K-Wires for Lateral Humeral Condyle Fractures.

Background: Good outcomes have been described for pediatric lateral condyle fractures treated by open reduction and fixation using either screws or Kirschner wires (K-wires). No studies have compared the biomechanical properties of the 2 fixation methods. We hypothesized that screw fixation would be more biomechanically stable than K-wire fixation.

The effect of sliding knots on the suture-tendon interface strength: a biomechanical analysis comparing sliding and static arthroscopic knots.

Background: The tissue-suture interface remains the most common site of failure in rotator cuff repairs. It is currently unknown if arthroscopic sliding knots injure the tissue and weaken the suture-tendon interface.

Purpose: To evaluate the effect sliding knots have on the strength of the suture-tendon interface.
