Comparison of treatment outcome comparing patients who had two-stage revision for PJI in cemented and cementless THA
| Variable | Cementeda (n = 36) | Cementless (n = 72) | p value |
|---|---|---|---|
| Infection control | |||
| Interim re-debridement | 6 (17%) | 7 (10%) | 0.296 |
| Reinfection after reimplantation | 8 (22%) | 5 (7%) | 0.021 |
| Other complications | |||
| Femoral fracture in the interim period | 1 (3%) | 2 (3%) | 1.000 |
| Dislocation after reimplantation | 6 (17%) | 5 (7%) | 0.128 |
| Periprosthetic femoral fracture after reimplantation | 4 (11%) | 0 (0%) | 0.004 |
| Cup loosening | 0 (0%) | 1 (1%) | 0.477 |
| Stem loosening | 1 (3%) | 1 (1%) | 0.613 |
p values were calculated from chi-square test; bold—the significance level was p < 0.05
