摘要: Abstract We evaluated the clinical, radiographic, and survivorship outcomes in a series of 418 threaded hydroxyapatite-coated acetabular cups (Arc2f; Osteonics, Allendale, NJ) implanted consecutive 384 patients undergoing primary total hip arthroplasty. In all cases, cup was screwed into prepared acetabulum. Bone screws were used to provide secondary fixation. At minimum 10-year follow-up, 304 available for analysis. The cumulative (mechanical failure as endpoint) at that time 99.43% ± 0.0104. Two hundred seventy-six hips full clinical radiographic review or after tenth anniversary. No unstable implants noted; implant fixation interfaces classified “stable bone ingrown,” migration rate zero. Based on achieved with this implant, our results compare favorably reported best cemented cementless designs. Copyright 2003, Elsevier Science (USA). All rights reserved.
