ConforMIS(Burlington, MA) has announced that the company won European approval for the iDue bicompartmental knee resurfacing implant and iJig instrumentation, both custom designed to fit and work together. This is the only custom made bicompartmental knee resurfacing system currently available on the market, as we have reported before. For our previous coverage of this technology, see flashbacks below.
The iDuo is the first and only patient-specific, bicompartmental resurfacing implant on the market. It is designed for patients whose arthritic damage is limited to either the medial or lateral compartment of the knee, in addition to the patellofemoral compartment. Each iDuo is custom designed and manufactured from an individual patient’s CT scan using ConforMIS’ patented iFit® technology, allowing for an entirely personalized fit.
The iDuo resurfaces only the affected areas, preserving far more bone than a traditional knee replacement surgery. The iDuo also preserves the anterior and posterior cruciate ligaments, which helps to maintain natural knee kinematics. The extent of tissue and bone conservation with the iDuo helps patients retain their future surgical options.
The iDuo surgical procedure utilizes patient-specific instrumentation called iJigs that are designed from the same imaging data as the implant. The iJig cutting a nd placement guides eliminate manual sizing during surgery and provide tactile guidance to precisely place the implant, significantly reducing the number of bone cuts required for the surgery, simplifying the steps, and increasing the reproducibility of surgical results.
