    摘要： An isometer for determining isometric graft tunnel placement for lateral side surgical augmentation or reconstruction for anterolateral or posterior lateral rotary knee instability. This graft tunnel placement isometry assessment and measurement device is designed to be used with a graft and an extra-articular technique that restores rotatory, lateral, and anterior/posterior knee stability when used by itself or in combination with intra-articular ACL/PCL reconstruction. The isometer includes an elongated body with a slider rod that slides horizontally within the body and a cannulated fixed stylus attached transversely to the first end of the elongated body. Within that cannulated fixed stylus is a guide pin that slides freely but that can also be fixed using a fixed-stylus set screw. Similarly, a cannulated movable stylus is attached transversely to the first end of the slider rod, and within that cannulated movable stylus is a guide pin that slides freely but that can also be fixed using a movable-stylus set screw. There is a pointer encircling the slider rod that slides with the slider rod, but whose position along the slider rod can also be adjusted manually. The slider rod may also have a rotatable member that allows each end of the slider rod to rotate relative to the other end. The rotatable member obviates slider rod impingement during operation. To determine rotary knee isometry during knee reconstructive surgery, the guide pins are positioned over previously identified lateral reconstruction tunnel sites. The guide pins are then driven into the bone tunnel sites and the knee put through a full range of motion by flexing and extending the knee while the isometer position is maintained and the pointer movement is monitored. If movement of the pointer is unacceptably large, the guide pins are re-set, re-positioned and re-driven into different pre-identified lateral reconstruction tunnel sites, and pointer movement during full range motion is again monitored until movement is acceptably small.

    摘要： A bioabsorbable implantable device for replacing sutures in construction of a composite graft in ligament replacement surgery. In certain embodiments the device has a female component and a male component where the female component receives and secures the male component. In other embodiments the components of the device are in the shape of a rivet or a staple. The bioabsorbable implantable devices can be used for securing tendon grafts to bone blocks and for holding together the fibers of the tendon graft when the bone-tendon-bone graft is inserted into a patient during surgery. The bioabsorbable implantable device may also be part of a package for use in surgery. The package includes a sterile container for holding at least a graft that is of a predetermined length and width. The package may also include bone blocks. The package is marked as to the graft size including the width and the length of the graft. The graft and the bone blocks may be autogenous, allogenic or constructed from man-made materials.

    摘要： 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.

    摘要： 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. The system permits the bone pieces to be pulled against one another between the rigid member and the locking mechanism.

This graft tunnel placement isometry assessment and measurement device is designed to be used with a graft and an extra-articular technique that restores rotatory, lateral, and anterior knee stability when used by itself or in combination with intra-articular ACL reconstruction. The isometer includes an elongated body with a slider rod that slides horizontally within the body and a cannulated fixed stylus attached transversely to the first end of the elongated body. Within that cannulated fixed stylus is a guide pin that slides freely but that can also be fixed using a fixed-stylus set screw.
