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. The tapered shank has a first diameter at a first end of the tapered shank opposite the threaded portion which is smaller than the predetermined diameter of the drilled hole and a second diameter adjacent the threaded portion which is larger than the predetermined diameter so that the tapered shank engages the replacement ligament in the tunnel as the pin is inserted through the drilled hole in the replacement ligament to force the replacement ligament against a side wall of the tunnel to promote healing of the replacement ligament within the receptor bone. The pin further includes a head coupled to an end of the body portion adjacent the threaded section for driving the pin into the receptor bone…
