An anchor for tendons used in the reconstruction of a ligament, particularly of the cruciate ligament of the knee, comprising a ring element (2) which can be inserted in a bore formed in the tibia or in the femoral condyle of the knee and an annular flange (3) for abutment against the region that surrounds the opening of the bore in the condyle in which the ring element (2) has been inserted, the ring element (2) being provided, on opposite sides, with two portions (8, 9) which protrude from it and are mutually aligned so as to be external to the cortex when the ring element is inserted in the bore, the annular flange (3) being provided with an opening (11) whose breadth is such as to allow the ring element (2) to pass through it and allow the protrusions (8, 9) to engage on the flange (3) in diametrically opposite positions.
