BACKGROUND
Cementless fixation of total hip arthroplasties (THAs) is often
favored in young, high-demanding patients due to the conservation of
valuable bone-stock and easier revision if loosening has occurred.
Long-term outcome data of the spongy metal structured implant used
in the present study in patients younger than 65 years are
still lacking.
METHODS
We conducted a retrospective chart review and functional
investigation (Merle d'Aubigné score, SF-12) of patients
younger than 65 years at implantation treated with a spongy
metal structured THA (n = 79) from one orthopedic
university center from 1985 to 1989.
RESULTS
At a 19-year mean follow-up (range: 15.3 - 21.3 years), the
overall stem survival rate was 93.7 %, and the overall cup
survival rate was 82.3 %. Revision surgeries of the stem were
performed in all cases for aseptic loosening at an average of
15.3 ± 3.5 years after implantation.
Acetabular components were revised for aseptic loosening and
recurrent dislocation after inlay revision on an average of
11.8 ± 4.7 years after implantation. No
other device related complications occurred within the 19-year
follow-up period. No correlation was found between time of revision
and gender or age. Clinical outcome scores (Merle d'Aubigné
score, SF-12) revealed excellent to good results of the implanted
THAs in 87 % of patients.
CONCLUSIONS
We conclude that spongy metal structured cementless THAs implanted
in young patients have an excellent survival and provide trustworthy
clinical results at 19 years of follow-up.
