Polykandriotis E, et al. - Authors studied 40 flexor tendons to evaluate a polytetrafluoroethylene (PTFE) suture (SERAMON, Serag-Wiessner) as a potential material for repairing a flexor tendon to improve functional consequences. They found all repairs in the PTFE group failed due to cheese wiring. They observed the loading strength of the repaired tendon in the polypropylene (PPL) was 49.90 ± 16.05 N when a Kirchmayr–Kessler core and epitendinous repair technique was used whereas, in the PTFE group, the loading strength was noted 73.41 ± 19.81 N. Conclusively, they described PTFE with excellent strength characteristics in comparison to PPL for flexor tendon repairs. Despite standard 2 strand techniques were determined incompetent to bear the higher biomechanic requirements.
