| Abstract: | We evaluated the survival of 827 acetabular revisions with Trabecular Metal Revision Shell using data from a nationwide arthroplasty register. The mean age of the patients was 69.1 years. The 3-year overall survivorship was 92% (95% confidence interval, 88-95), which coincides with earlier reports. Revision rate for aseptic loosening was only 2%. The most common reason for revision was dislocation of the prosthesis with or without malposition of the socket (60%). Age was found to have significant effect on cup survivorship: each additional year in age decreased the risk of revision by 2.4% (95 % confidence interval, 0.1-4.7; P = .044). We found no differences in survival rates between aseptic and septic revisions. Furthermore, sex, diagnosis, and hospital volume did not affect the survival. |
