An implant for attaching a tendon or ligament to a hard tissue is provided. The implant includes a shaft, a convex first surface, a flat or concave second surface, first pillars for contacting a hard tissue, first slots to be occupied by the hard tissue, second pillars for contacting a tendon or ligament, and second slots to be occupied by the tendon or ligament. The implant has a first surface ratio of the sum of the volumes of the first slots to the sum of the volumes of the first pillars and the volumes of the first slots of 0.40: 1 to 0.90:1, and a second surface ratio of the sum of the volumes of the second slots to the sum of the volumes of the second pillars and the volumes of the second slots of 0.60:1 to 0.98:1. The second surface ratio is greater than the first surface ratio.
