Tensile strength of cross-stitch epitenon suture

Using a computerized tensiometer, the mechanical properties of two types of repair in the canine flexor digitorum superficialis tendon were examined. The slope and ultimate tensile strength of a cross-stitch epitenon suture were compared to those of a simple over-and-over running epitenon suture. Both epitenon sutures were combined with a modified Kessler core suture. Suture material was 6/0 monofilament nylon for the epitenon suture, and 4/0 braided polyester for core suture. Average relative values of individual ultimate tensile strength for the cross-stitch group was 245% compared to that for the running suture group. There was no discrepancy in slope between the two groups.
