[Bone tissue response to the echelon-type uncemented femoral component in revision total hip arthroplasty (THA)].

Introduction: We present the preliminary, short-term results of a cohort study of revision THA focused on aseptic loosening and aimed at assessing the metadiaphyseal bone ingrowth biological response of an uncemented femoral implant with an extensive porous coating.

Material And Methods: The clinical, X-ray and personal satisfaction outcomes (SF-36) of four patients were assesessed. We had performed four exchange THAs due to a diagnosis of clinical and radiographic aseptic prosthetic loosening, with symptoms of anterior thigh pain.
