“…Biphasic polyurethane foam blocks have been previously used as a bone substitute in biomechanical investigations for failure strength, cycling, and stiffness evaluations. [10][11][12] In the investigation by Barber and Herbert, biphasic polyurethane foam blocks reveal no difference in the means between ultimate failure load for the individual anchors but have narrower ranges and standard deviations. Thus, the authors found more consistent results with the polyurethane foam blocks, supporting their further use in other biomechanical investigations.…”

Barber's biomechanical work is well known to Arthroscopy's readers as thorough, comprehensive, and inclusive of new designs as they become available. In "All-Suture Anchors: Biomechanical Analysis of Pullout Strength, Displacement, and Failure Mode," the latest iteration, Barber and Herbert test all-suture anchors in both porcine femurs and biphasic foam. While we await in vivo clinical trials that compare all-suture anchors to currently used anchors, Barber and Herbert have provided data to inform anchor choice, and using their biomechanical data at time zero from all-suture anchor trials in an animal model, we can determine the anchors' feasibility for human clinical investigations.

“…Though this test is far from the actual application, it clearly shows the potential of this novel design. A study by Barber recently showed that the determination of the pull-out force of BPTB grafts with interference screws in PU foam resulted in comparable values to those in human cadavers [26]. To the best of the authors' knowledge, only one study presented a comparable fixation approach with a similar material.…”

“…The density of these Sawbones blocks was selected considering the material properties of the human bone. Sawbones blocks have similar material properties (e.g., density, Young’s modulus, and Poisson’s ratio) compared to actual bone samples [ 30 ]. Dehestani et al showed BASHTI technique is more suitable for young patients.…”

Background Bone and Site Hold Tendon Inside (BASHTI) technique is an organic implant-less technique for anterior cruciate ligament (ACL) reconstruction with some clinical advantages, such as speeding up the healing process, over implantable techniques. The study aims to compare the mechanical properties of BASHTI technique with the conventional interference screw technique. Methods To investigate the mechanical properties, 20 in-vitro experimental tests were conducted. Synthetic dummy bone, along with fresh digital bovine tendons, as a graft, were used for experiments. Three loading steps were applied to all specimens, including a preconditioning, a main cyclic, and a pull-out loading. Results The mechanical characters of an interference screw technique using an 8 mm tendon diameter, including fixation strength, average cyclic stiffness (ACS), and average pull-out stiffness (APS) were found to be 439 ± 132 N, 10.3 ± 5.3 kN/mm, and 109 ± 40 N/mm, respectively. In the case of an interference screw using a 9 mm tendon, the fixation strength, ACS, and APS were obtained 549 ± 87 N, 10.3 ± 4.7 kN/mm, and 91 ± 13 N/mm, respectively. In parallel, the fixation strength, APS, and ACS of BASHTI technique using an 8 mm tendon were 360 ± 123 N, 3.3 ± 0.6 kN/mm, and 79 ± 27 N/mm, respectively, while, for 9 mm tendon 278 ± 103 N, 2.4 ± 1.2 kN/mm, and 111 ± 40 N/mm, were reported for fixation strength, APS, and ACS respectively when BASHTI technique was used. Conclusion About 50% of interference screw samples showed superior mechanical properties compared to BASHTI technique, but in another half of the samples, the differences were not significant (N.S.). However, due to organic advantages of BASHTI technique and lower cost, it could be used as a substitute for interference screw technique, especially where fast recovery is expected.
