Clinical and radiographic results with the Trilock femoral component--a wedge-fit porous ingrowth stem design.
Eighty-one cementless Trilock (Depuy, Warsaw, IN) femoral components were observed for 2 to 6 years. The following end points were examined:  revision (none), pain score less than 5 (six patients), and radiographic settling greater than 5 mm (three patients).  Four patients (5%) had thigh pain at follow-up.  No complete radiopaque lines could be identified around the porous surface of the femoral components.  By any standard, the wedge-fit tapered cementless femoral design is successful.  As the follow-up period lengthens, a survivorship analysis can be done to assess the long-term potential of the Trilock design.
