description <strong>Background and Objective:</strong> Patients with anteromedial arthritis who require a knee replacement could receive either a unicompartmental knee replacement (UKR) or a total knee replacement (TKR). This review has been undertaken to identify economic evaluations comparing UKR and TKR, to evaluate the approaches that were taken in the studies, to assess the quality of reporting of these evaluations and consider what they can tell us about the relative value for money of the procedures. <strong>Methods:</strong> A search of MEDLINE, Embase and the Centre for Reviews and Dissemination National Health Service Economic Evaluation Database was undertaken to identify relevant studies in January 2016. Study characteristics were described, the quality of reporting and methods assessed using the CHEERS checklist, and study findings summarised. <strong>Results:</strong> 12 studies satisfied the inclusion criteria. Five were within-study analyses while another was based on a literature review. The remaining six studies were model-based analyses. All studies were informed by observational data. While methodological approaches varied, studies generally had either limited follow-up, did not fully account for baseline differences in patient characteristics or relied on previous research that did not. Quality of reporting was generally adequate across studies except for considerations of the settings to which evaluations applied and the generalisability of the results to other decision making contexts. UKR was generally associated with better health outcomes and lower costs than TKR in the short-term. Initial cost savings associated with UKR seem to persist over patients’ lifetimes even after accounting for higher rates of revision. For older patients, initial health improvements also appear to be maintained, making UKR the dominant treatment choice. However, for younger patients findings for health outcomes and overall cost-effectiveness are mixed with the difference in health outcomes depending on the lifetime risk of revision and patient outcomes following revision. <strong>Conclusions:</strong> UKR appears to be less costly than TKR. For older patients UKR is also expected to lead to better health outcomes, making it the dominant choice. However, for younger patients health outcomes are more uncertain. Future research should better account for baseline differences in patient characteristics and consider how the relative value of UKR and TKR varies depending on patient and surgical factors.
