Before the global launch of GMK Efficiency single use instrumentation for total knee replacement – which has experienced sustained growth since its introduction into the market – Swiss Climate completed an environmental impact analysis in collaboration with Medacta. Swiss Climate calculated the CO2 equivalent emissions (CO2e) associated to each step of the GMK Efficiency life cycle and evaluated the impact on a per-surgery basis, making it possible to compare the CO2e associated with the conventional metal instrumentation life cycle and the GMK Efficiency CO2e value.
Based on studies conducted in hospitals in Switzerland, UK, USA and Canada which calculated the total amount of CO2 emissions during one-year of practice, and on the analysis by Swiss Climate on CO2 emissions linked to GMK Efficiency usage, it was calculated that if these hospitals had used GMK Efficiency instead of re-usable metal instrumentation, the additional CO2 emissions would have accounted for a minuscule increase between 0.04% and 0.2% of their yearly emissions [1-3].
For continual environmental responsibility, Medacta completely offsets the total amount of CO2 connected to GMK Efficiency. Through active support for environmental sustainability projects initiated by Swiss Climate, Medacta GMK Efficiency instrumentation was rewarded with the “CO2 neutral” certificate.
It is also important to note that by eliminating washing and sterilization, which are mandatory steps to prepare the metal instrumentation for surgery, the GMK Efficiency offers a saving of about 400 litres of water for every knee operation [4-6].
