"literature article entitled, ¿comparing the long-term results of two uncemented femoral stems for total hip arthroplasty¿ by stephen m.Petis, md, et al, published by the journal of arthroplasty (2015), vol.30, pp.781-785, was reviewed.The purpose of this study was to 1) determine if there is a difference in survivorship across two different cementless femoral stems, and 2) are clinical and radiographic outcomes similar at long-term follow-up.The authors retrospectively reviewed all patients who had a total hip arthroplasty using either a proximally coated cementless stem (competitor product) or extensively coated cementless stem (prodigy, depuy) between 1996 and 2002.Implanted products: prodigy stem, 185 duraloc cups, 185 depuy polyethylene liners, 179 articul/eze and 6 biolox forte femoral heads.Results: 4 prodigy stem revisions: 2 for stem fractures post-op, 1 for aseptic loosening, 1 for periprosthetic femur fracture post-op.5.3% reported thigh pain.17.7% reported severe stress shielding of the femur.31 cases of pedestal formation.22 liner revisions for polyethylene wear.3 acetabular component revisions (unspecified) for joint instability.3 cup revisions for acetabular osteolysis and/or aseptic loosening of the cup.There were no further complications listed within the text.".
