The 10- to-13 year performance of 307 Mallory Head cementless tapered total hip replacements in 283 @entity1 was assessed. Eighty-five percent of @entity1 had a diagnosis of @entity571 . Fifty-one percent of @entity1 were @entity1 . The mean @entity1 age was 64 +/- 10 years. The @entity13500 Loc cementless acetabular component and @entity702 alloy femoral heads were used in each @entity1 . At final followup, 37 (13%) @entity1 died, 32 (10%) had revision surgery, and two (1%) were lost to followup. No femoral stem was revised for @entity1349 , but one was revised because of @entity295 and one was revised because of a @entity3564 . Wear, osteolysis, and loosening were problems with the @entity13500 Loc cementless acetabular components and 31 (10%) acetabular components required revision because of these mechanisms. The mean Harris hip score at final followup of the remaining @entity1 was 87 +/- 14 points. Three percent of these @entity1 had thigh @entity158 . Radiographic assessment revealed that no femoral stem or acetabular socket was definitely or probably loose. Three-dimensional wear assessment using the Devane technique was 0.35 mm per year. The Mallory Head cementless, tapered femoral component performed well in the @entity1 in the current study, but unfortunately, the clinical results were compromised by the use of a suboptimal cementless acetabular component, the use of @entity691 that was gamma-irradiated in air, and by the use of @entity702 alloy femoral heads. Future developments obviously will be in the areas of better acetabular component design, alternate @entity691 sterilization methods, and enhancements of the femoral stem in terms of offset choices, neck design, and perhaps ingrowth surface.
