The Odds of Complications After Total Knee Replacement for Patient With and Without Previous Knee Fusion
| Outcome | Odds ratio (with:without fusion) | 95% confidence interval |
|---|---|---|
| Knee resection arthroplasty | 15.8 | 4.3–58.5 |
| Infection | 4.0 | 0.9–17.8 |
| Complications during index admission | 2.7 | 0.9–8.3 |
| Revision | 1.9 | 0.25–14.5 |
| Repeat fusion of the knee | 82.0 | 15.3–44.2 |
An odds ratio > 1 implies that the complication is more likely to occur after conversion of a previous knee fusion. In all cases the estimate is adjusted for age, gender, diagnosis, admission year, follow-up time, and surgeon and hospital volume. A 95% confidence level that includes 1 suggests that the result was not significant at p < 0.05. Significant findings are highlighted.
