For the medical treatment of damage or rupture in the flexor digital tendon, finger flexor tendon suture surgery is used. In previous studies, various core suture methods have indicated that important factors affect biomechanical properties, including the number of suture strands. Recently, asymmetric sutures have been reported to be effective. However, it has not been studied what is the optimal asymmetry or required degree of asymmetry. The purpose of this study is to evaluate the strength evaluation and gap formation in asymmetric core suture under cyclic load testing. Suture method was 6 types. In result, the core repairs with 3 mm or more asymmetry in suture purchases in two tendon ends showed significantly greater fatigue strength and significantly smaller gaps compared with 1 mm asymmetry in core suture repair.
