Management of Infected Total Joint Replacement
Fisman et al. performed an excellent study examining the cost-effectiveness of two-stage exchange arthroplasty and open debridement with prosthesis retention in elderly patients with infected total hip arthroplasty. Lifetime direct medical costs as well as indirect costs from loss of productivity were assessed using a Markov model. Incremental ratios demonstrated that when compared with exchange arthroplasty, initial debridement and retention had lower cost-effectiveness ratios ($500-$21,800/QALY) in all cohorts regardless of gender.
