“…Outcomes were considered at two time horizons: 1 and 5‐years post‐operative. Patients moved between health states based on transition probabilities derived from both prospectively collected institutional data and values extracted from the literature 2,21–26 . Each health state was associated with unique utility as quantified by quality‐adjusted life‐years (QALYs) and costs in United States Dollars ($ USD), also derived from institutional and literature‐reported values.…”

BackgroundThe purpose of this study was to assess the cost‐effectiveness of a novel, fluoroscopy‐based robotic‐assisted total hip arthroplasty (RA‐THA) system compared to a manual unassisted technique (mTHA) up to 5 years post‐operatively.MethodsA Markov model was constructed to compare the cost‐effectiveness of RA‐THA and mTHA. Cost‐effectiveness was defined as an Incremental Cost‐Effectiveness Ratio (ICER) <$50 000 or $100 000 per Quality Adjusted Life Year (QALY).ResultsRA‐THA patients experienced lower costs compared to mTHA patients at 1 year ($20 865.12 ± 9897.52 vs. $21 660.86 ± 9909.15; p < 0.001) and 5 years ($23 124.57 ± 10 045.48 vs. $25 756.42 ± 10 091.84; p < 0.001) post‐operatively. RA‐THA patients also accrued more QALYs (1‐year: 0.901 ± 0.117 vs. 0.888 ± 0.114; p < 0.001; 5‐years: 4.455 ± 0.563 vs. 4.384 ± 0.537 p < 0.001). Overall, RA‐THA was cost‐effective (1‐year ICER: $−61 210.77; 5‐year ICER: $−37 068.31).ConclusionsThe novel, fluoroscopy‐based RA‐THA system demonstrated cost‐effectiveness when compared to manual unassisted THA.

Background: Total hip arthroplasty (THA) is the benchmark surgical treatment of advanced and symptomatic hip osteoarthritis. Preliminary evidence suggests that the robotic arm-assisted (RAA) technology yields more accurate and reproducible acetabular cup placement, which may improve survival rate and clinical results, but economic considerations are less well-defined. The purpose of this study was to compare the cost effectiveness of the RAA THA with manual THA (mTHA) modalities, considering direct medical costs and utilities from a payer's perspective. Methods: A Markov model was constructed to analyze two potential interventions for hip osteoarthritis and degenerative joint disorder: RAA THA and mTHA. Potential outcomes of THA were categorized into the transition states: infection, dislocation, no major complications, or revision. Cumulative costs and utilities were assessed using a cycle length of 1 year over a time horizon of 5 years. Results: RAA THA cohort was cost effective relative to mTHA cohort for cumulative Medicare and cumulative private payer insurance costs over the 5-year period. RAA THA cost saving had an average differential of $945 for Medicare and $1,810 for private insurance relative to mTHA while generating slightly more utility (0.04 quality-adjusted life year). The preferred treatment was sensitive to the utilities generated by successful RAA THA and mTHA. Microsimulations indicated that RAA THA was cost effective in 99.4% of cases. Conclusions: In the Medicare and private payer scenarios, RAA THA is more cost effective than conventional mTHA when considering direct medical costs from a payer's perspective. Level of Evidence: Economic Level III. Computer simulation model (Markov model)
