Through a trainee research collaborative, we have studied the changes in practice of 12 T&O departments across the East of England over the first four weeks of the UK lockdown and COVID-19 pandemic, comparing to activity levels with the corresponding period in 2019. We focused on changes in T&O practice, training and redeployment of Trainees. Units differ considerably in several aspects of practice. We found a 97% reduction in elective operating, 64% reduction in elective outpatient activity and 37% reduction in operative trauma. 58% of trainees continued working in T&O clinics, with an average of 6 operative cases over this period. Our modelling suggests that the impact on training will persist; counter-measures must be incorporated into central recovery planning.
