Short summary
Deep periprosthetic joint infection following knee replacement is a serious complication feared by surgeons. Our aim was to investigate if seasonality of deep infection incidence exists in a national registry of knee replacement patients. We extracted data from over 100 000 procedures, investigating if patients operated on during the summer had increased risk of re-operation due to infection. We found no signal of periodicity, meaning the summer season is not a risk factor for deep infection.
