1 Cost-Effectiveness of Bariatric Surgery Prior to Total Knee Arthroplasty in the Morbidly Obese by Alexander S. McLawhorn, Daniel Southren, Y. Claire Wang, Robert G. Marx, and Emily R. Dodwell J Bone Joint Surg Am Volume 98(2):e6 January 20, 2016 ©2016 by The Journal of Bone and Joint Surgery, Inc.

2 A conceptual organization of the Markov decision model is illustrated. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.

3 Tornado diagram illustrates the results of the one-way sensitivity analyses for each model variable. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.

4 A chart showing the results of two-way sensitivity analysis evaluating the utility of primary total knee arthroplasty (TKA) in morbidly obese patients compared with the probability of weight loss after bariatric surgery. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.

5 A graph depicting the ICER for the combined protocol compared with the probability of successful weight loss after bariatric surgery. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.

6 A chart showing the acceptability curves generated from the probabilistic sensitivity analysis. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.

7 A scatterplot depicting the ICER derived from each iteration of the model from the probabilistic sensitivity analysis. Alexander S. McLawhorn et al. J Bone Joint Surg Am 2016;98:e6 ©2016 by The Journal of Bone and Joint Surgery, Inc.
