“…[12][13][14][15][16][17][18] We chose the Achilles tendon in this study, because it is a commonly injured tendon in humans. The Achilles tendon of the rabbit is composed of three parts, which offers a good model and makes experimentation relatively easy.…”

Achilles tendon rupture is a common injury. Absorbable sutures are not commonly used because of their limited strength properties. Recently, sutures with prolonged strength retention properties have been developed. The aim of the study is to test the mechanical properties of recently developed poly-L/D-lactide (PLDLA) sutures in comparison with polyglyconate (Maxon) sutures. PLDLA (0.2 mm thick) and Maxon (4.0) sutures were studied in vitro by immersion in a buffered saline solution (pH 7.4). Tensile strength tests were done on sutures retrieved after 1-26 weeks. In vivo, they were implanted in the subcutis of 32 rabbits. Tensile strength tests were done on sutures retrieved after 1-6 weeks. The sutures were also used to repair the Achilles tendon in rabbits. Maximum force before breaking and percentage elongation of tendons were determined. Although PLDLA had a lower initial tensile strength than Maxon, PLDLA showed more prolonged tensile strength retention than Maxon. Tendons repaired with PLDLA, however, had a lower strength than Maxon-repaired tendons at six weeks (insignificant difference). PLDLA has more prolonged tensile strength properties compared with Maxon. Thus, PLDLA offers an alternative to Maxon in repair of the Achilles tendon.

“…It may be treated by immersion in oil, wax, or silicone to decrease the natural capillarity, however, this process diminishes knot security. 29 Silk loses 30% of its tensile strength by 2 weeks after subcutaneous implantation in rats. 29 At one month, tensile strength is 59% of its value at one week.3n Loss of tensile strength is accelerated after 2 months and by 6 months the suture has no holding p~w e r .~' Silk has excellent handling characteristics, but has certain limitations in application.…”

“…Herrmann 10 designed experiments to evaluate changes in breaking strength and knot security in the early postoperative period. Changes in tensile strength of sutures after implantation in animals are of concern because the in vivo environment is thought to alter the physical properties of sutures, whether in strand or knot configuration.…”

“…Herrmann 10 reported a decrease of 30% in strength for silk loops (3 squared throws) of 2/0 size during 2 weeks of implantation. We recorded slightly higher ranges of strength decrease for the 4 thrown sliding knots during 20 days of implantation.…”
