A SOFT TISSUE FIXATION DEVICE (AKA ACL GRAFT FIXATION DEVICE)

摘要

A soft tissue fixation device for use in ACL or CrCL reconstruction has a base member provided with a passageway extending perpendicularly from its top surface through its bottom surface. The passageway is sized to allow soft tissue to be inserted through the passageway. The fixation device also includes an affixing member attachable to the base member. The base member has a notched section in the top surface extending from the passageway to a first perimeter section of the base member sized to accommodate at least a portion of the graft. Either surgical grade tissue glue or at least one perpendicularly extending spike is used to secure the base member to the bone. The base member is also provided with a sleeve whose interior wall surfaces form a part of the passageway and is sized to be inserted into the bone opening. The affixing member is provided with a series of teeth members extending downward from its lower surface. The teeth members are positioned so that when the affixing member is attached to the base member the teeth members will extend across and into the notched section of the top surface of the base member. The opposite ends of the affixing member is shaped to fit into aligned notches positioned along perimeter sections of the base member bottom surface for attaching the clip member to the base member.
