Summary
Ten percent of surgeons use custom-fit total knee arthroplasty systems, with many interested in adopting the technology. Cost and lack of clinical data are barriers, though some report reduced procedure times.
Area of Science:
- Orthopaedic Surgery
- Medical Technology Innovation
Background:
- Custom-fit arthroplasty systems utilizing magnetic resonance imaging (MRI) for component placement are emerging.
- Assessing the current adoption and perceived benefits of this novel technique is crucial.
Purpose of the Study:
- To determine the prevalence of custom-fit positioning total knee arthroplasty (TKA) use among orthopaedic surgeons.
- To evaluate surgeons' perceptions of benefits and barriers associated with this technology.
Main Methods:
- A survey of 50 orthopaedic surgeons was conducted at a regional meeting.
- The survey comprised 19 questions focusing on custom-fit TKA usage and attitudes.
Main Results:
- 10% of surveyed surgeons currently use custom-fit positioning technology for TKA.
- 29 out of 40 non-users expressed interest in adopting the technique.
- Primary barriers cited were cost and insufficient clinical outcomes reports.
Conclusions:
- Widespread adoption of custom-fit TKA technology may increase if further clinical studies demonstrate efficacy and longer-term benefits.
- Despite cost concerns, some surgeons report potential benefits, including reduced procedure times.
