Orthopedic implants and related surgical methods for using same. The implants have suture bore geometries that facilitate performance of the surgical methods, thereby providing for improved optimal biomechanical force application in various anatomies. The implants include suture bores that have an angled / diagonal, or skewed, orientation within the anatomical planes (lateral / sagittal and frontal / coronal). The suture bores have the skewed orientation so that the adjacent soft tissues (i.e., tendons or ligaments) can be advanced via the suture therethrough in superior-inferior and inferior-superior directions. Openings, or holes, at the ends of the suture bores are configured to approximate the adjacent associated soft tissue to the implant.
