Conformis announced that independent, retrospective review of hospital data suggest that iTotal® knee replacement technology is more cost-effective than leading traditional, off-the-shelf implants.
The retrospective review was performed at a single medical institution between 2016 and 2019 using a financial database and electronic health records. Patient demographics, total direct costs, length of stay (LOS) and opioid use were all investigated.
The review comprised three groups:
- Primary group – patient-specific implant (Conformis iTotal)
- Comparison group – traditional implant (Zimmer Persona®)
- Control group – traditional implant (Stryker Triathlon®)
Mean Length of Stay Analysis:
- 1.35 days for Conformis iTotal patients
- 1.99 days for Zimmer Persona patients
- 1.83 for Stryker Triathlon patients
Total Direct Costs Analysis:
- $9,341 for Conformis iTotal® patients (savings of $1,006 to $1,263 per patient)
- $10,347 for Zimmer Persona® patients
- $10,604 for Stryker Triathlon® patients
The study concludes that total direct costs for hospital admissions appear to be more cost-effective with Conformis iTotal, and variables such as operative time and length of stay also appear to favor a patient-specific implant over traditional, off-the-shelf implants.
