Therefore, ACL treatment is important in preventing knee problems from developing. The treatment of choice for ACL tears is surgery (ACL reconstruction), and the most popular tendons for ACL reconstruction are the patellar tendon, hamstring tendon (semitendinosus and gracilis tendons), and bone-patellar tendon-bone. The present study compares the tensile strength of autografts used in ACL reconstruction to identify the optimum autograft for ACL in terms of mechanical properties. Methods Cadavers were dissected, and the Achilles tendons, quadriceps tendons, hamstring tendons (semitendinosus and gracilis tendons), patellar tendon grafts, and ACLs were harvested. Tensile tests of each tendon graft were performed using a Shimadzu Autograph AG-IS 100 kN tester (Shimadzu, Kyoto, Japan). Results The mean difference in tensile strength between ACL and other grafts was lowest for the quadriceps in both males and females (p < 0.001), meaning that ACL and quadriceps grafts are more compatible than other tendon grafts in terms of tensile strength. Conclusion The present study found the lowest mean difference in tensile strength to be between the ACL and the quadriceps tendon, suggesting that the use of the quadriceps tendon in ACL reconstruction will yield more positive outcomes.eninfo:eu-repo/semantics/openAccessquadriceps tendontensile strengthreconstructionautograftanterior cruciate ligament (acl)Article15610.7759/cureus.3992737409216WOS:001059787300034N/A
