This study evaluates the utility of a simple, cost-effective system: high-strength suture tying over a bone bridge (BB). Its effectiveness as standalone fixation and as a supplement to standard interference screw (IS) fixation is compared with IS alone and supplemented with other commercial systems.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A biomechanical study was conducted using six fixation methods tested on 61 specimens with bovine extensor tendons in porcine tibial models.

When combined with IS, BB significantly improved performance, achieving an ultimate load to failure of 500.55\u2009\u00b1\u2009151.24\u00a0N, comparable to commercial systems, and reducing cyclic displacement to 4.82\u2009\u00b1\u20090.83\u00a0mm. Hybrid fixation methods lowered early failure rates to 10%, compared with 30\u201340% in single-method fixations, confirming enhanced stability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Hybrid fixation methods are more reliable than simple ones for tibial fixation.
