Insights
Hip replacement surgery trends show increasing bipolar hemiarthroplasty (BH) and primary total hip arthroplasty (THA) rates in Korea. Revision THA rates remained stable, with an overall decrease in revision burden observed.
Area of Science:
- Orthopedic surgery
- Health services research
- Epidemiology
Background:
- Hip arthroplasty procedures, including bipolar hemiarthroplasty (BH) and total hip arthroplasty (THA), are common treatments for hip conditions.
- Understanding procedural trends and revision burdens is crucial for healthcare planning and resource allocation.
Purpose of the Study:
- To document the procedural numbers and rates of BH and primary/revision THAs in Korea from 2007-2011.
- To stratify procedure prevalence by demographics and hospital type.
- To estimate and evaluate changes in the revision burden over time.
Main Methods:
- Analysis of national Korean Health Insurance Review and Assessment Service data (2007-2011).
- Inclusion of 60,230 BHs, 40,760 primary THAs, and 10,341 revision THAs.
- Stratification by age, gender, and hospital type; estimation of revision burden.
Main Results:
- A steady increase in the number and rate of BH and primary THAs observed from 2007-2011.
- No significant change in the number or rate of revision THAs.
- Overall annual revision burden for THA decreased from 22.1% to 18.9% during the study period.
- Higher rates of primary and revision THAs in men compared to women.
Conclusions:
- While BH and primary THA rates increased, revision THA rates remained stable in Korea.
- The overall revision burden for THA showed a decreasing trend.
- Findings contrast with some Western data, particularly regarding revision THA trends and gender-specific rates.
Abstract:
We analyzed national data collected by the Health Insurance Review and Assessment Service in Korea from 2007 to 2011; 1) to document procedural numbers and procedural rate of bipolar hemiarthroplasty (BH), primary and revision total hip arthroplasties (THAs), 2) to stratify the prevalence of each procedure by age, gender, and hospital type, and quantified, 3) to estimate the revision burden and evaluate whether the burden is changed over time. Our final study population included 60,230 BHs, 40,760 primary THAs, and 10,341 revision THAs. From 2007 to 2011, both the number and the rate of BHs, primary THAs increased steadily, whereas there was no significant change in revision THAs. Over the 5 yr, the rate of BHs and primary THAs per 100,000 persons significantly increased by 33.2% and 21.4%, respectively. The number of revision THAs was consistent over time. The overall annual revision burden for THA decreased from 22.1% in 2007 to 18.9% in 2011. In contrast to western data, there were no changes in the number and rate of revision THAs, and the rates of primary and revision THAs were higher for men than those for women. Although 5 yr is a short time to determine a change in the revision burden, there have been significant decreases in some age groups.
