Table 2.
Cumulative revision percentages (CR) within 10 years for osteoarthritis patients with a primary total knee arthroplasty (TKA)
| TKA | Male |

|---|---|---|---|---|
| Cemented | Uncemented | Cemented | Uncemented | |
| Age | CR (95% CI) | CR (95% CI) | CR (95% CI) | CR(95% CI) |
| 50–54 | 11 (9.3–13) | 13 (8.0–21) | 11 (10–13) | 10 (7.1–15) |
| 55–59 | 9.4 (8.5–11) | 8.9 (6.2–13) | 8.9 (8.1–9.8) | 7.7 (5.6–11) |
| 60–64 | 6.4 (5.7–7.1) | 7.6 (5.6–11) | 6.8 (6.3–7.4) | 6.6 (4.9–8.7) |

| 85–90 | 1.6 (1.0–2.6) | – a | 1.7 (1.3–2.2) | 2.0 (0.9–4.9) |
aThe subgroup of uncemented TKAs in males 85–90 years was too small to calculate valid 10-year cumulative risk percentages.
