Study: Conformis iTotal Knee More Cost-Effective than Off the Shelf Implants

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®)

Results indicate:

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.
