Evidence for prevalence of osteolysis and survival rate for metal-on-metal total hip replacement
| Study | Implant | Hips (n) | Mean age (years) | Mean follow-up (year) | Survival rate (%) | Osteolysis (%) |
|---|---|---|---|---|---|---|
| Dastane et al141 | Metasul (multicup design mated with APR stem) | 30 | 44.7 | 5.5 | 100% at 5 years | 0% |
| Girard et al147 | Metasul Armor/Allofit cup Zweymuller SL stem/Muller cemented stem | 47 (ON 54%) | 25 | 9 | 94.5% at 10 years* | 6% on femur 4% on pelvis |
| Kim et al143 | CLS Metasul bearing | 68 (ON 87%) | 37 | 7 | 100% at 7 years | 1.4% on femur 1.4% on pelvis |
| Park et al144 | S-ROM (DePuy) | 165 (ON 54%) | 56.7 | 2.3 | 98.8% at 2 years | 6% on femur |
Note:
*
No significant differences in survival rate with different preoperative diagnoses.
