We studied a consecutive series of 81 cementless total hip
arthroplasties in 80 patients using the second generation ESKA
cementless spongy metal hip replacement. The study end-point was
implant revision and both function as well as satisfaction with
treatment outcome were assessed.Mean age at the time of surgery was
50.9 years [range 23-73]. No patient was lost to follow-up and 75
patients (76 hips) could be included in the final analysis at a mean
follow-up of 7.9 years [range 7.0-10.0]. Survival rate without
loosening as the end-point was 100% for the femoral component and
99% for the acetabular component (one cup revision). Two cups and
one stem had to be revised for recurrent dislocation, resulting in a
total implant survival at follow-up of 99% for the femoral component
and 96% for the acetabular component. Very good functional results
were obtained with a mean Merle d' Aubigné score of 15.5 +/-
2.9 at 7.9 years after surgery. Satisfaction with treatment outcome
was reported in 88%. 95% of patients would recommend the performed
procedure to a friend. Peri-operative complications without revision
occurred in eleven patients (14%).We report excellent survival rates
of the cementless spongy metal hip arthroplasty at a mean follow-up
of eight years, particularly considering the young age of many of
the patients.
