The disclosure provides apparatus and methods of use pertaining to a surgical broach for creating a noncircular bore in bone. Embodiments include a surgical punch having a handle coupled with a broach shaft. The broach shaft features a cylindrical portion with a boss projecting radially from the cylindrical portion. When the broach shaft is pressed into bone, it creates a circular bone tunnel having a relief groove projecting radially from and in communication with the circular bone tunnel. Thus, when an implant such as a return anchor for a suture is pressed into the resulting noncircular bore, a return path of the suture passes through the relief groove projecting from the bone tunnel, thereby reducing suture traffic through an internal passage of the anchor and relieving the need for an outer sidewall of the anchor to accommodate the return suture path. Other embodiments are disclosed.
