We’ve covered ConforMIS‘ personalized knee resurfacing solutions before, but now the company has announced its iTotal CR knee replacement system has been cleared by the FDA. Using technology similar to that utilized in its iDuo and iUni knee resurfacing devices, personalized implants are designed using 3D CT scans of patients’ knees. ConforMIS claims that personalized knee replacements will result in better fit and lower contact stresses, and will allow surgeons to preserve more of patients’ existing bone than current knee replacement solutions.
From the press release:
The iTotal CR builds on ConforMIS’ patented iFit® technology for generating patient-specific implants and individualized jigs. As with all ConforMIS implants, the system uses computer modeling to build a 3D image of a patient’s knee from CT scans. That image then guides the proprietary design and manufacture of not just the jigs, but the personalized implants that resurface the patients’ articular surfaces.
The patient-specific process produces customized implants with unparalleled advantages. Each iTotal CR is made to fit an individual patient precisely without the under-sizing and overhang common with standard systems. The ability to maximize coverage for each patient is combined with one of the broadest implant contact areas in the industry, resulting in extremely low polyethylene contact stress.
