title: Revision hip arthroplasty using an extensively porous coated stem: medium term results.
abstract: This is a medium-term, prospective assessment of 56 revision total hip replacements using a.cementless, extensively porous-coated femoral stem.with a mean follow-up of 6 years. All implants demonstrated evidence of bony ingrowth and stable fixation with no cases of loosening, instability, deep infection, stress shielding, subsidence or osteolysis at last follow-up. Complications included two intra-operative fractures, three dislocations, one superficial infection, and one patient with thigh pain. No femoral stems were revised. Good to excellent clinical outcomes were achieved on Harris Hip Score (90% (n = 47/52), Western Ontario and McMaster Universities Index (92% (n = 48/52), and University of California Los Angeles activity score (96% (n=50/52). This supports the use of this system in the revision hip surgery armamentarium.
