The Odds of Complications After Total Knee Replacement for Patient With and Without Previous Knee Fusion

OutcomeOdds ratio (with:without fusion)95% confidence interval
Knee resection arthroplasty15.84.3–58.5
Complications during index admission2.70.9–8.3
Repeat fusion of the knee82.015.3–44.2
  • 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.
