ABSTRACT
BACKGROUND:
The purpose of this study is to determine the long-term (up to 27 years) results of a modified technique applying strut allografts combined with a reduction osteotomy over an extensively porous-coated stem.METHODS:
We reviewed the results of 399 revision total hip arthroplasties (for aseptic loosening in 390 hips and septic loosening in 9 hips) in 369 patients (mean age 58 ± 13 years, range 22-65) performed with an extensively porous-coated femoral stem combined with a cortical strut onlay allograft. The mean follow-up was 23 years (range 20-27).RESULTS:
The mean Harris Hip Score was 84 ± 16 points (range 35-100) at the final follow-up. The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 21 ± 16 points (range 12-53) at the final follow-up. The mean University of California Los Angeles activity score was 6.1 points (range 5-8). A Kaplan-Meier survivorship analysis at 23 years of follow-up showed that the survival rate of the femoral component was 95.5% (95% confidence interval 89-98) with aseptic loosening or revision for any reason and it was 91.5% (95% confidence interval 85-95) if septic loosening was included.CONCLUSION:
We found good results in terms of longevity and functional outcome using this modified technique. Future mechanical studies in addition to controlled clinical studies are warranted.Palabras clave
