A method of tissue repair using a surgical assembly that includes the steps of assembling an implant and a driver, capturing tissue with the implant, installing the implant with the captured tissue in a socket or tunnel, advancing a tapered section of a set screw in the implant, thereby expanding the implant and fixing the implant with the captured tissue in the socket or tunnel, and releasing the driver from engagement with the set screw as the distal end of the set screw reaches the implant's closed end. A surgical assembly that includes an expandable implant having a hole with an entrance at a rear end of the implant and a closed end; a set screw, an implant insertion section, a driver engagement section, and a tapered section, where the implant insertion section is received in the hole of the implant, and a driver that is engaged with the set screw.
