Abstract
A method and apparatus for performing a surgical repair may involve fixation of a repair material, such as a ligament or tendon in knee ligament repair procedure, to an internal cortical contact area in a bone. The cortical bone contact area may be located immediately adjacent an opening in the bone's surface through which the repair material extends. The repair material may be engaged with the contact area by way of a fixation device, such as a device that is attached to the repair material and functions as a stop member. An illustrative fixation device may include an annular portion with an aperture through with the repair material passes. The repair material may be attached to a securing portion that extends from the annular portion.
Claims25
A surgical fixation device, comprising:
- a base portion including an aperture constructed and arranged to receive a joint repair material, the base portion having a contact surface and being constructed and arranged to contact a bone at the contact surface and secure the joint repair material relative to the bone surface;
- and
- a securing portion constructed and arranged to secure the joint repair material to the base portion, the securing portion being arranged to engage with the base portion on a side of the base portion opposite the contact surface and extending away from the base portion, the securing portion having a part that extends across the aperture;
- wherein the base portion and the securing portion are arranged to be deployed entirely within a bone opening and to resist tension applied on the joint repair material secured to the securing portion in a direction from the securing portion toward the contact surface, the securing portion being arranged to position the joint repair material in contact with bone in the bone opening.
A surgical fixation device, comprising:
- an annular portion having a bone contact surface on a first side and an opening adapted to receive a ligament repair material;
- and
- a securing portion attached to a second side of the annular portion opposite the first side and having a portion that extends across the opening of the annular portion, the securing portion having an elongated member extending in a direction away from the contact surface and being adapted to secure a ligament repair material passing through the opening to the annular portion;
- wherein the annular portion and the securing portion are arranged to be deployed entirely within a bone opening and to resist tension applied on the ligament repair material secured to the securing portion in a direction from the securing portion toward the contact surface.
