Insights
The COVID-19 pandemic significantly reduced hip and knee replacement surgeries in Ontario. Post-resumption, hip replacement activity disproportionately increased compared to knee replacements, impacting surgical backlog recovery planning.
Area of Science:
- Orthopedic Surgery
- Public Health
- Epidemiology
Background:
- Ontario declared a state of emergency in March 2020 due to the COVID-19 pandemic.
- Elective total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures were deferred from March 19 to May 26, 2020.
- This study analyzes surgical activity trends during this deferral period.
Purpose of the Study:
- To review unit sales data of THA and TKA procedures in Ontario.
- To identify trends in surgical activity during the COVID-19 deferral period.
- To assess the relative change in THA and TKA activity post-resumption.
Main Methods:
- Unit sales data for THA and TKA procedures in Ontario from January 2019 to December 2020 were analyzed.
- Femoral stems indicated THA procedures; primary femurs indicated TKA procedures.
- Data were collected from all orthopedic companies contributing to the dataset.
Main Results:
- THA activity decreased by 53% between March and May 2020 compared to 2019.
- Post-resumption (June-September 2020), THA activity was 122.8% of TKA activity, compared to 87.3% in 2019.
- A disproportionate increase in THA compared to TKA activity was observed in 2020.
Conclusions:
- Provincial directives for COVID-19 control led to a substantial reduction in THA and TKA activity in 2020.
- The data suggest a disproportionate increase in THA versus TKA activity post-resumption.
- Findings have implications for recovery planning and addressing the surgical backlog for THA in Ontario.
Background:
In March 2020, an emergency was declared in the province of Ontario owing to the COVID-19 pandemic. From March 19 to May 26, all elective total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures were deferred. The purpose of this study was to review the unit sales data of THA and TKA procedures in Ontario over this time period to identify any trends in surgical activity.
Methods:
Unit sales data for all THA and TKA procedures performed in Ontario between January 2019 and December 2020 were reviewed. All orthopedic companies contributed to the data set. Femoral stems were considered an indicator of THA procedures, while primary femurs were considered an indicator of TKA procedures. Data were analyzed to determine trends in THA and TKA procedures during the deferral period and the relative change in THA and TKA activity following resumption.
Results:
There was a 53% reduction in THA activity between March and May of 2020 when compared to the same interval in 2019. From June to September of 2019, THA sales activity was 87.3% that of TKA. From June to September of 2020, THA sales activity was 122.8% that of TKA.
Conclusion:
Provincial directives aimed at controlling the outbreak of COVID-19 contributed to a substantial reduction in THA and TKA activity in 2020. Compared to 2019, there was a disproportionate increase in THA compared to TKA activity in 2020 following resumption of surgical services. These data have implications in recovery planning for the surgical backlog of THA in Ontario.
