Prospective Evaluation of Total Hip Arthroplasty With a Cementless, Anatomically Designed, Porous-Coated Femoral Implant: Mean 11-Year Follow-up

The performance of an anatomically designed femoral implant with porous titanium mesh coating was assessed in patients undergoing total hip arthroplasty. The stem, with built-in 12° anteversion, was implanted in neutral position relative to the long axis of the femur through a cementless press-fit application. The only requirement was the presence of sufficient thickness within the cortical bone of the femoral metaphysis to support the stem. Ninety-one evaluable patients were followed up for a minimum of 10 years. Patients tolerated weight-bearing activity within 24 hours after surgery. Only 1 femoral component required revision because of loosening. Most patients showed uniform bony ingrowth. Quality of life was markedly improved. The anatomically designed, porous-coated implant provides robust performance which has general utility in a wide range of patients.
