AI Technical Summary

Technical Problem

Current fastening devices for ACL reconstruction, such as interference screws and cortical buttons, face issues with graft tension loss, migration, and incomplete fastening due to the porosity of trabecular bone, leading to potential failure of the repair and mechanical instability in the joint.

Method used

A medical fastening device featuring a first and second fastening element with a through conduit and fastening conduit arranged at an angle, forming an annular proximal surface that houses the graft, providing a larger fastening passage and increased rigidity, and a distal appendage for suspending the graft without the need for knots or sutures, ensuring secure anchoring within the bone tunnel.

Benefits of technology

The device enhances the ultimate tensile strength of the graft, prevents migration, and ensures complete fastening, reducing the risk of graft slippage and damage, thereby improving the mechanical properties and stability of the joint post-reconstruction.
