Resuming elective hip and knee arthroplasty in the COVID-19 era: a unique insight into patient risk aversion and sentiment.

ABSTRACT

INTRODUCTION: There has been guidance from the government and orthopaedic community on how best to ensure the safety of our patients and colleagues as we recommence elective surgery in the UK. The primary aim was to determine what proportion of patients feel they should proceed with their elective hip and knee arthroplasty surgery during the COVID-19 climate. The secondary aim was to investigate what variables affected this decision. METHODS: Patient information from a single surgeon's waiting list in a district general hospital were recorded. A standardised telephone discussion was had with all the patients noting the severity of pain and the potential reasons for not wanting to proceed with surgery. RESULTS: A total of 70.6% (96/136) of patients wished to proceed with surgery; 29.4% (40/136) did not wish to proceed. The decision to proceed with surgery was not correlated with sex, American Society of Anesthesiologists grade or COVID-19 risk. Those who wished to proceed with surgery had a mean age of 68.5 years while those who did not had a mean age of 72.4 years (P = 0.03). Within the matched subgroups, patients under the age of 70 years were more willing to proceed with primary hip arthroplasty surgery (87.9%) compared with primary knee arthroplasty surgery (57.1%; P = 0.007); 75% of the patients who did not wish to proceed with surgery expressed concerns about perioperative COVID-19 infection. CONCLUSION: There is a significant proportion of arthroplasty patients on waiting lists who would be willing to accept the increased risks associated with COVID-19 to undergo surgery on an urgent basis. The subgroup of younger patients awaiting hip arthroplasty is more willing than those awaiting knee arthroplasty to proceed with surgery.
