AbstractIntroductionThe incidence of Achilles tendon rupture shows a gradually increasing trend, which is mainly managed by minimally invasive treatment due to its advantages, such as low wound infection rate. At present, the firmness of the commonly applied minimally invasive suture method for Achilles tendon remains controversial. Our research group has developed a novel suture method for Achilles tendon, which has achieved favorable clinical outcomes. Therefore, this experiment aimed to explore the optimal approach to repair Achilles tendon rupture through comparing the biomechanical strength of the commonly used Achilles tendon suture methods currently.Materials and methods6 fresh frozen human cadaveric Achilles tendon specimens were sutured by three kinds of technique, and were tested through the cyclical loading after repair.ResultsResults of cyclical loading showed that, the repair using the new technique was stronger after 10 cycles, 1000 cycles, and rupture. Moreover, the new technique had displayed superior anti-deformation strength to that of the Ma-Griffith technique.ConclusionsOur experimental results demonstrate that, the new technique proposed by our research group can attain comparable biomechanical properties to those of the Krachow technique. However, the sample size in this study is small, and further clinical trials are warranted.
