Publikation All-inside meniscal repair devices compared with their matched inside-out Vertical mattress suture repair. Introducing 10,000 and 100,000 loading cycles(SAGE, 01.09.2014) Rosso, Claudio; Müller, Sebastian; Buckland, Daniel M.; Schwenk, Tanja; Zimmermann, Simon; de Wild, Michael; Valderrabano, VictorAll-inside arthroscopic meniscal repairs are favored by most clinicians because of their lower complication rate and decreased morbidity compared with inside-out techniques. Until now, only 1000 cycles have been used for biomechanical testing. Hypothesis: All-inside meniscal repairs will show inferior biomechanical response to cyclic loading (up to 100,000 cycles) and load-to-failure testing compared with inside-out suture controls. Study Design: Controlled laboratory study. Methods: Bucket-handle tears in 72 porcine menisci were repaired using the Omnispan and Fast-Fix 360 (all-inside devices) and Orthocord 2-0 and Ultrabraid 2-0 sutures (matched controls). Initial displacement, displacement after cyclic loading (100, 500, 1000, 2000, 5000, 10,000, and 100,000 cycles) between 5 and 20 N, ultimate load to failure, and mode of failure were recorded, as well as stiffness. Results: Initial displacement and displacement after cyclic loading were not different between the groups. The Omnispan repair demonstrated the highest load-to-failure force (mean 6 SD, 151.3 6 21.5 N) and was significantly stronger than all the other constructs (Orthocord 2-0, 105.5 6 20.4 N; Ultrabraid 2-0, 93.4 6 22.5 N; Fast-Fix 360, 76.6 6 14.2 N) (P \ .0001 for all). The Orthocord vertical inside-out mattress repair was significantly stronger than the Fast-Fix 360 repair (P = .003). The Omnispan (30.8 6 3.5 N/mm) showed significantly higher stiffness compared with the Ultrabraid 2-0 (22.9 6 6.9 N/mm, P \ .0001) and Fast-Fix 360 (23.7 6 3.9 N/mm, P = .001). The predominant mode of failure was suture failure. Conclusion: All-inside meniscal devices show comparable biomechanical properties compared with inside-out suture repair in cyclic loading, even after 100,000 cycles. Clinical Relevance: Eight to 10 weeks of rehabilitation might not pose a problem for all repairs in this worst-case scenario.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Three anchor concepts for rotator cuff repair in standardized physiological and osteoporotic bone: a biomechanical study(Elsevier, 06.10.2019) de Wild, Michael; Dietschy, Alain; Claudio, Rosso; Rosso, Claudio01A - Beitrag in wissenschaftlicher ZeitschriftPublikation European Society of SportsTraumatology, Knee Surgery and Arthroscopy(05/2018) Rosso, Claudio; de Wild, Michael; Weber, Timo; Müller, Sebastian06 - PräsentationPublikation Pull-out Strength of Three Anchors for Rotator Cuff Repair in Standardized Physiological and Osteoporotic Bone(05/2018) Rosso, Claudio; de Wild, Michael; Dietschy, Alain; Weber, Timo06 - PräsentationPublikation Three Anchors For Rotator Cuff Repair Biomechanically Compared In Standardized Physiological And Osteoporotic Bone(09/2018) Rosso, Claudio; de Wild, Michael; Dietschy, Alain; Weber, Timo; Müller, Sebastian06 - PräsentationPublikation Biomechanical comparison of Three Anchors for Rotator Cuff Repair in Standardized Physiological and Osteoporotic Bone - introducing 1000 loading cycles(09/2018) Müller, Stefan; Dietschy, Alain; de Wild, Michael; Rosso, Claudio; Weber, Timo06 - PräsentationPublikation New Lasso-Loop 360° Technique For Arthroscopic Suprapectoral Biceps Tenodesis – A Biomechanical Comparison(2016) de Wild, Michael; Rosso, Claudio; Müller, Sebastian; Flury, Rebekka; Zimmermann, Simon; Lafosse, Laurent; Bongiorno, Vito06 - Präsentation
