Pulse lavage is recommended in all modern total joint arthroplasty operations in the UK. The common current pulse lavage is a disposable battery-operated system. AC and power tool powered models are commercially available in the UK. We performed a carbon emissions analysis of each model to evaluate the reduction in the carbon footprint of the arthroplasty operations at one trust and extrapolated the data to scale the possible economic and environmental benefits. Introducing a power tool driven pulse lavage system can reduce the carbon footprint of pulse lavage by 50% compared to the battery and AC-powered options. Additionally, we have reduced the economic impact of one trust by switching to a "greener" alternative pulse lavage system. In trusts where a power tool-driven pulse lavage is not possible, we advocate using AC-powered kits that are less wasteful than the more commonly used battery-powered options.
