The outcome of rerevision of an extensively porous-coated stem with another extensively porous-coated stem.

Despite excellent results, failure of osseointegration does occur in femoral revisions performed with extensively porous-coated stems. This study examined the outcome of rerevision of a failed extensively porous-coated femoral stem with yet another extensively porous-coated stem. Between 1980 and 2000, we performed 711 femoral revisions using an extensively porous-coated device. Fifteen patients (16 hips) were known to have undergone a rerevision of this femoral component using another porous-coated stem. At latest follow-up, 2 patients (3 hips) were deceased, leaving 13 patients. At a mean follow-up of 9.8 years, none of the cementless stems had required another revision (100% survivorship), and 12 (92%) of the 13 stems were bone ingrown based on radiographic examination.
