Appendix
We conducted a systematic review of papers to determine robotic TKA failure rates to derive an annualized failure rate for robotic TKA revision.

Scatterplot depicting the total costs and QALYs of the 10,000 iterative simulations of the probabilistic sensitivity analysis where the model’s sensitive parameters are varied across distributions: QOL of a robotic-assisted TKA at 1-year and >1 year, the QOL of a conventional TKA at 1-year and >1 year, the probability of early (≤1 year) and late (>1 year) conventional TKA failure, the probability of early (≤1 year) and late (>1 year) robotic-assisted TKA failure, the QOL of an optimal TKA, and the annualized total per-case cost of robotic-assistance.
