The purpose of this study was to evaluate the initial tendon\u2010fixation strength of the Lark\u2010Loop technique in arthroscopic suprapectoral biceps tenodesis and compare it with others commonly used techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty\u2010three porcine superficial flexor digitorum tendons were harvested from a local slaughterhouse and randomly divided into three groups to perform three tendon fixation techniques (Lasso\u2010Loop stich group, Lark\u2010Loop stich group or Krackow stich group; 11 tendons each group) with a No. 2 suture, respectively. Each tendon was pre\u2010tensioned in 5\u00b0N for 2\u00a0min and then cyclically loaded 5 to 30\u00b0N for 500\u2009cycles to assess displacement. After cyclic loading, the tendon was loaded to ultimate tendon\u2010suture configuration failure at the rate of 1\u2009mm\/s. Finally, the mode of failure and the construct stiffness of the tendon were recorded and calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After cyclical loading, the displacement of the Lark\u2010Loop group was equivalent to the Krakow group (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.9999) but significantly smaller than the Lasso\u2010Loop group (<jats:italic>P<\/jats:italic> =\u20090.0009). The ultimate load to failure for the Lark\u2010Loop was equivalent to the Krakow technique group (<jats:italic>P<\/jats:italic> =\u20090.1463) but significantly greater than the Lasso\u2010Loop group (<jats:italic>P<\/jats:italic> &lt;\u20090.0001). The stiffness for the Lark\u2010Loop was equivalent to the Krakow group (<jats:italic>P<\/jats:italic> =\u20090.4718) but significantly greater than the Lasso\u2010Loop technique group (<jats:italic>P<\/jats:italic> &lt;\u20090.0001). In the Lark\u2010Loop and Krackow group, all the tendons failed by suture breakage, while all the tendons failed by suture cutting through the tendon in the Lasso\u2010Loop technique group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Lark\u2010Loop suture technique has biomechanical properties comparable to Krackow and superior to the Lasso\u2010Loop in terms of suture displacement, ultimate load to failure, and stiffness.
