A carpal tunnel release tool and methods for using the same are disclosed. Embodiments of the carpal tunnel release tool include a guide with an angled track and a knife that fits into and follows the angled track. In one embodiment, the knife is retracted into the guide as it is advanced along the track to cut the ligament. In an alternate embodiment the blade is extended outwardly from the surface of the guide as the blade is advanced along the track. Other embodiments include a projection at the terminal end of the track that maintains the position of the ligament over the guide, serves as a type of cutting block to ensure complete bisecting of the ligament, and can aid the surgeon in placement of the guide beneath the ligament. Further embodiments include an inserter that inhibits tissue entering the track as the guide is advanced beneath the ligament.
