In performing the flexor tendon repair, peripheral suture is essential to improve the sufficient strength and to accomplish the early active mobilization of repaired flexor tendons. It has been reported the interlocking cross-stitch peripheral suture is increased the strength. The purpose of this study was to evaluate about various interlocking cross-stitch peripheral suture under cyclic loading conditions. All pairs of the artificial roll tendon model were sutured using only peripheral sutures with 6-0 Polypropylene. Suture method was 11 types. An initial cyclic load of 10 N for 500 cycles was applied and increased by 5 N for an additional 500 cycles at each new load until rupture. In result, the interlocking cross-stitch peripheral suture that the suture strand is increase, improved the strength of the specimen. However, suture strand of 16 times or more is unrealistic. Therefore, it was considered to be valid suture strand of 12 times.
