Contributions to displacement and resistance of the meniscus-suture complex in transtibial meniscal root repair Prado-Novoa, María Pérez-Blanca, Ana Estébanez-Campos, María Belén Nadal-Martínez, Fernando Espejo-Reina, Alejandro Ceccarelli, Marco Rodillas-Lesiones y heridas-Tratamiento Biomecánica This work analyses in a porcine model the contributions of meniscal tissue, suture thread and meniscus-suture interaction to the permanent displacements generated at the repaired root after surgery to re-insert the posterior meniscal root using a transtibial pullout technique. Medial porcine menisci with a single suture applied at the posterior horn were subjected to cyclic and load-to-failure tests. Elongations of the different components of the meniscus-suture complex were determined applying photogrammetry. Results showed that after low intensity cyclic loading, the main contribution to permanent root displacements was due to the thread (51.2%), while no cutting of the suture through tissue occur at the interface. Under load-to-failure conditions, suture cutting started at a significantly higher load level (Suture Retention Strength, SRS), always before and close to the first local maximum of the load-elongation curve, and progressed rapidly afterwards causing the final failure of all specimens 2019-09-18T09:43:54Z 2019-09-18T09:43:54Z 2019 2019 conference output https://hdl.handle.net/10630/18382 eng 8th International Conference in Mechanics and Materials in Design Bolonia, Italia Septiembre, 2019 open access
