A resurfacing implant composed of a femoral cap (2) with an outer face (7), an inner face (8), a peripheral edge (11), a central axis XX' passing through the pole P of the cap (2), an equatorial axis YY' perpendicular to the first axis, and a point C of intersection between the main axes XX', YY' forming the centre of the radius of curvature of the outer (7) and inner (8) faces, characterized in that it includes guide elements composed of a cylindrical finger (9) with a base (90) connected to the inner face (8) at a point D, which is offset laterally with respect to the pole P of the hemispherical profile of the femoral cap (2), and stabilizing elements (10) arranged on the perimeter of the inner face (8), and having a profile arranged in a plane parallel to that containing the guide elements (9).
