Summary
Benchmarking total hip arthroplasty implant revision risk is feasible in the US using a regional registry. However, some current hip implants may not meet early benchmarking criteria, raising concerns about their performance and utilization.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Health services research
Background:
- Benchmarking arthroplasty implant revision risk is crucial for assessing implant performance.
- International guidelines for arthroplasty benchmarking have been developed.
- The Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) was used to test US feasibility.
Purpose of the Study:
- To assess the feasibility of implementing international arthroplasty benchmarking guidelines in the United States.
- To evaluate the performance of hip implants using a US-based registry.
Main Methods:
- Utilized data from the MARCQI registry for primary elective total hip arthroplasty (THA) for osteoarthritis (2012-2018).
- Applied international guidelines requiring at least 250 procedures at risk for benchmarking.
- Used predefined revision rate thresholds: 2% at 2 years and 3% at 5 years.
Main Results:
- 72,949 primary THA cases were analyzed, with 1369 revisions.
- 29 and 6 implant combinations met the minimum case requirement at 2 and 5 years, respectively.
- Three implant combinations failed to meet the 2-year benchmark: Secur-Fit/Trident, Anthology/Reflection 3, Taperloc 133/G7.
Conclusions:
- The international benchmarking guideline is implementable in the US via a regional registry.
- A significant number of currently used hip implants may not achieve early benchmarking.
- This highlights potential concerns regarding the performance and increasing utilization of certain implant combinations.
