  • Publication number: 20240065855
    Abstract: In A bone plug insertion instrument (1) is proposed for inserting a bone plug (70) into a target bone tunnel. The bone plug insertion instrument (1) comprises (a) an elongated housing (10) defining a first central axis, and comprising an at least partially tube-shaped insertion portion, and a handling portion, the at least partially tube-shaped insertion portion (11) defining, substantially orthogonally to the first central axis, an inner cross-sectional area at least partially surrounded by a bone engaging end surface of the at least partially tube-shaped insertion portion; and (b) an elongated plunger (40) comprising an actuating portion and a bone plug driving portion with a bone plug engaging end surface (43) having an engaging area of 20% to 80% of the inner cross-sectional area. The elongated plunger (40) is configured to move relative to the elongated housing (10) between a first position and a second, different position.

  • Publication number: 20220331127
    Abstract: A bone plug compression instrument that can be used to reshape includes a first compression element having a first cavity, a second compression element having a second cavity, and a base portion for supporting the first and second compression elements. The second compression element moves between first and second positions. In the first position, the bone plug compression instrument forms an open configuration, in which the first and second cavities are spaced apart from each other allowing the bone plug in a substantially non-compressed state to be inserted in a space between the first and second cavities In the second position, the bone plug compression instrument forms a closed configuration, in which the first and second cavities press against each other to form a combined cavity for compressing the bone plug received in the combined cavity. The combined cavity has at least a partially converging shape.

  • Patent number: 11344420
    Abstract: The present invention relates to a modular knee prosthesis assembly kit for replacement of resected articular surfaces of a distal femur of a first patient side. The kit comprises at least one bi-condylar component sized and shaped to substantially replace resected posterior and distal condylar bone portions; and at least a first trochlear groove component and a second trochlear groove component, each sized and shaped to replace a resected trochlear groove bone portion. The first trochlear groove component comprises a first patella articulation path defining a first trochlear groove direction angle. The second trochlear groove component comprises a second patella articulation path defining a second trochlear groove direction angle. An assembly of the bi-condylar component and one of the first and second trochlear groove components forms a substantially complete femoral knee prosthesis. The second trochlear groove direction angle is different from the first trochlear groove direction angle.

  • Publication number: 20200360028
    Abstract: The invention relates to a surgical method for creating a bone tunnel in target bone by utilizing a punch instrument which is sized and shaped for removal of a bone plug out of the target bone. By removing the bone plug, the femoral tunnel can be created. The punch instrument comprises an impaction handle and punch head having a bore. The punch head comprises a cutting edge arranged circumferentially around the bore at a cutting end of the punch head. By using of the punch instrument, a bone plug can be retrieved without creating bone drilling debris. Furthermore, the bone plug can be retrieved as a solid piece of graft, to be used to as a graft at another site in the body thereby promoting healing and reducing recovery time after surgery.

  • Patent number: 9289285
    Abstract: A device for implantation in a bone is disclosed, wherein this device is a component part of a system, for controlled loading of the reconstructure anterior crucual ligament (ACL) of a knee joint. The device may comprise an outer body, which is provided with a damping mechanism between a distal end and a proximal end. Arranged inside the damping mechanism there is at least one securing element for fixing at least one thread which, at the proximal end of the device, is guided out from the outer body through an aperture in the base.
