ConforMIS has launched a new iteration of its unicompartmental knee resurfacing device, iUni G2. The company claims that enhancements to the iUni G2 include an improved patient specific and wear optimised design, instrument changes for even simpler surgical techniques, and iView patient-specific images for improved surgical planning.

The company’s partial knee resurfacing systems use proprietary technology and patient-specific imaging data to personalise an implant and instrumentation set for each patient, providing superior fit and performance, said the company.

ConforMIS has introduced the iUni G2 in November 2009, and it is currently available for both medial and lateral compartment treatment. The company’s patient-specific approach offers an array of advantages to patients, surgeons and hospitals.

The company claims that the iUni G2 offers patient-specific, anatomic fit for natural kinematics, full coverage of all weight bearing areas and a new implant designed for low contact stress and micro-motion. The iUni G2 provides patients benefit from a resurfacing solution with minimal bone resection, preservation of all ligaments, no intramedullary canal penetration, and the ability for a simple conversion to a primary total knee arthroplasty.

ConforMIS’ iUni G2 surgery uses iJig patient-specific instrumentation to reduce the number of surgical steps and to minimise intra-operative sizing and trials. In addition, the new iView patient-specific planning images introduce a new way to visualise joint preparation during surgery.
