Abstract: An apparatus is provided for use in installing a replacement ligament in substantially coaxial tibial and femoral tunnels formed in a knee joint by drilling upwardly from the anterior surface of the tibia below its plateau, through the plateau, and into the distal end of the femur. The replacement ligament has a leading end portion receivable in the femoral tunnel and a trailing end portion receivable in the tibial tunnel. The apparatus includes a sheath having a leading open end and an opposite end. The sheath has a calibrated scale printed thereon starting at the leading open end. The calibrated scale provides a visual indication of a distance from the leading open end of the sheath. The sheath is configured to receive the replacement ligament therein while the sheath is outside a patient's body with the leading end portion of the replacement ligament adjacent said open end and with the trailing end portion of the replacement ligament disposed toward said opposite end of the sheath.

Abstract: A preassembled disposable driver and suture anchor are provided for threaded engagement into a bone to provide an attachment point for soft tissue. The anchor is formed to have an externally threaded body portion for engaging the bone, a distal end portion, and a proximal end portion. When the anchor is threaded into an opening in a bone, the distal end portion is adjacent a bottom of the opening and the proximal end portion is adjacent a mouth of the opening. A suture is attached to said anchor having free ends extending outwardly from the bone opening. The driver is elongated and has a distal end which engages the proximal end of the anchor and a proximal end for gripping by the surgeon. The driver also has a slot for receiving the suture which extends away from the anchor.

The kit includes a drill for drilling a hole through the clavicle and the coracoid process. A plurality of guide pins for insertion into the shoulder to define an initial entry position and angle for the drill. The kit also includes a device for reducing the separation between the clavicle and the coracoid process while providing a desired separation therebetween.

Abstract: A pin is provided for securing a replacement ligament inside a tunnel of a receptor bone. The pin includes a body portion having a threaded section for engaging the receptor bone to anchor the pin in the receptor bone. The body portion also includes a tapered shank located adjacent the threaded portion. The tapered shank is configured to enter a drilled hole having a predetermined diameter formed in the replacement ligament to force the replacement ligament against the wall of the tunnel.
