Abstract
Objective: Bone And Site Hold Tendon Inside (BASHTI) is an implant-less technique
that can solve some of the problems associated with other Anterior Cruciate Ligament
(ACL) reconstructive methods. This study aims to investigate the effect of core bone
diameter variation on the biomechanical properties of a reconstructed ACL using BASHTI
technique.
Methods: A number of 15 laboratory samples of reconstructed ACL were built using
bovine digital tendons and Sawbones blocks. Samples were divided into three groups
with different core bone diameters of 8 mm, 8.5 mm, and 9 mm. The double-stranded
tendon size and bone tunnel diameter were 8 mm and 10 mm, respectively. A loading
scenario consisting of two cyclic loadings followed by a single cycle pull-out loading was
applied to the samples simulating the after-surgery loading conditions to observe the
fixation strength.
Results: Results showed that the core bone diameter had a significant effect on the
failure mode of the samples (P=0.006) and their fixation strength (P<0.001). Also, it
was observed that the engaging length and the Average Cyclic Stiffness (ACS) of them
were influenced by the core bone diameter significantly (engaging length: P=0.001, ACS:
P=0.007), but its effect on the average pull-out stiffness was not significant (P=0.053).
Conclusion: It was concluded that core bone diameter variation has a significant impact
on the mechanical properties of ACL reconstruction when BASHTI technique is used, and
it should be noted for surgeons who use BASHTI technique.
