A femoral guide for precisely positioning a guide wire on a bone surface of the femur includes a body having a lumen for receiving a guide wire and a tongue protruding from the body for engaging an edge or reference point on the bone surface with the tongue being spaced a predetermined distance from a longitudinal axis of the lumen. The lumen includes an opening allowing a guide wire extending through the lumen to contact the bone surface at a location spaced from the edge substantially the predetermined distance with the tongue engaging the edge. A stylus on the body can be driven into the bone to secure and stabilize the femoral guide prior to driving the guide wire into the bone through the lumen. With the guide wire driven into the bone, a bone tunnel can be formed substantially concentrically or coaxially along the guide wire such that a longitudinal axis of the bone tunnel will be disposed from the edge substantially the predetermined distance. Methods of precisely forming bone tunnels include the steps of engaging an edge of a bone surface with a tongue of the femoral guide, inserting a guide wire through a lumen of the femoral guide, driving the guide wire into the bone through the lumen and forming a bone tunnel in the bone along the guide wire such that a longitudinal axis of the bone tunnel will be disposed from the edge engaged by the tongue a distance substantially equal to the distance that the tongue is disposed from a longitudinal axis of the lumen.

A surgical screw driver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a rotatable operating shaft disposed at an angle to a drive shaft. A mechanism is on the drive shaft for retaining a bone screw. Methods of arthroscopic cruciate ligament reconstruction include the steps of introducing a surgical screw driver through a portal that is offset from the longitudinal axis of a bone tunnel and driving a bone screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.

Systems and methods for producing minimally invasive osteotomies to correct angular deformities of bones in and about the knee are disclosed. A method includes locating a plane in which the angle exhibited by the deformity is situated. An oblique cut is then made along a surface of the bone, such that the cut is transverse to the plane in which the angle is situated. Thereafter, the bone pieces are rotated about the cut relative to one another until a desired alignment between the bone pieces is achieved. To maintain the bone pieces in alignment, a device having an elongated body for extending into a tunnel between the bone pieces is provided. The system also includes a rigid member fixedly positioned at one end of the body. The rigid member is transverse to the body to engage one bone piece. The system further includes a locking mechanism at an opposite end of the body to engage the other bone piece.

A device for harvesting a tendon for cruciate ligament surgery includes an elongated outer member and an inner member disposed within the outer member, such that the outer and inner members are reciprocally movable relative to one another. The outer member has, at its distal end, a cutting edge for cutting connective tissues about the periphery of the tendon. The inner member is provided with a distal end and pathway into which the tendon is received during the harvesting procedure. The device further includes an actuator for moving the outer member and inner member between a non-actuated position, wherein the distal end of the outer member and the distal end of the inner member are at least in substantially even alignment, and an actuated position, wherein the distal end of the outer member is advanced beyond the distal end of the inner member, so as to expose the cutting edge for separating connective tissues about the periphery of the tendon.

A cannulated interference screw (10) and process for human implantation in an arthroscopic surgical procedure for replacement of a ligament, or the like. The interference screw is provided with a drill end (11) that extends longitudinally from an end of a cylindrical body (14), which drill end includes equally spaced flutes (12) therearound. The flutes extend into first and second cutting threads (15a) and (15b), respectively which cutting threads and threads (15) are formed around the cylindrical body. A center longitudinal passage (16) is formed through the interference screw drill end and cylindrical body, which passage is stepped outwardly within the cylindrical body into a hexagonal sided section (18) that is for receiving a sided end (20) of a driver (19) that is fitted therein. In practice, the cannulated interference screw is installed by sliding it along a guide rod (25) that is fitted in a prepared ligament tunnel (22) through a bone mass, alongside a bone block portion of a ligament (23) within the bone endosteum, which ligament is maintained in that tunnel under tension. The driver is also holed longitudinally to travel along the guide rod to fit into and turn the interference screw, providing fixation of the ligament in that tunnel.

A graft preparation table including a bone block drill guide and a suturing station. The bone block drill guide has a central tunnel and first and second parallel tunnels intersecting opposite sides of the central tunnel and parallel to the central tunnel. A bone plug is longitudinally inserted into the central column so that parallel grooves may be formed in the bone plug by drilling through the first and second parallel tunnels. The suturing station includes a tensioning track and a pair of suture blocks separated along the track. Each suture block includes a chamber for accommodating a bone plug and suture openings on opposite sides of the suture block. The distance between the suture blocks on the tensioning track may be adjusted to achieve the desired tension on the ligament replacement looped about the bone plugs. A stop pin is inserted into each suture block to hold the bone plug in its respective chamber. A needle carrying a suture is inserted through a suturing opening to attach the ligament replacement to the bone plug.

A suturing jig for attaching strands of tissue for use as a ligament replacement in cruciate ligament reconstruction. The suturing jig is provided with two pivotally attached arms having at their respective distal ends a clamping member. Each clamping member includes a plurality of openings. Each opening on one clamping member is aligned with a corresponding opening on the other clamping member for providing a path through which a needle may pass.

A surgical screwdriver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a flexible cannulated operating shaft. The shaft is formed by concentric coils including at least one clockwise helical coil and at least one counterclockwise helical coil. The screwdriver is used in methods of arthroscopic cruciate ligament reconstruction including the steps of introducing the screwdriver along a guide wire through a portal that is offset from the longitudinal axis of a bone tunnel and driving an interference screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.
