- Titel:
- Biomechanical evaluation of different suture materials for arthroscopic transtibial pull-out repair of posterior meniscus root tears.
- Abstract:
- To evaluate the biomechanical properties of four different suture materials for arthroscopic transtibial pull-out repair of posterior meniscus root tears, with special focus on the meniscus-suture interface.Forty fresh-frozen lateral porcine menisci were used. The posterior meniscus root was sutured in a standardized fashion with a simple stitch using four different suture materials: group A, No. 2 PDS(TM); group B, No. 2 Ethibond(TM); group C, No. 2 FiberWire(TM); and group D, 2-mm Fibertape(TM). Meniscus-suture constructs were subjected to cyclic loading followed by load-to-failure testing using a servo-hydraulic material testing machine.During cyclic loading, group D showed a significantly higher displacement after 100, 500, and 1,000 cycles compared to group A (p< 0.001, p = 0.001, and p = 0.001), and a significantly higher displacement after 100 and 500 cycles compared to group B (p = 0.010 and p = 0.045). Group C showed a significantly higher displacement compared to group A after 100 cycles (p = 0.008). The highest maximum load was observed in group D, with significant differences compared to group A (p = 0.013). Group B showed a significantly higher stiffness compared to group A (p = 0.023), and both group C and group D showed a significantly higher stiffness compared to group A and group B (p< 0.001).None of the evaluated suture materials provided clearly superior properties over the others during both cyclic loading and load-to-failure testing. Based on the results of this study, FiberWire(TM) may be the preferred suture material for transtibial pull-out repair of posterior meniscus root tears because of comparably low displacement during cyclic loading and high values for maximum load and stiffness. In the clinical setting, FiberWire(TM) may improve healing rates and avoid progressive extrusion of the meniscus after transtibial pull-out repair of posterior meniscus root tears.
