We initiated a position in ConforMIS Inc. (NASDAQ:CFMS), a company that develops custom implants for joint replacement procedures. The company uses proprietary software to design knee implants that match a patient’s unique anatomy. The company also uses 3D printing technology to manufacture customized instruments. In our view, ConforMIS has unique technology that is patent protected and disruptive to the $14 billion joint replacement industry. Studies have shown that the company’s knee implants result in better patient outcomes versus traditional off-the-shelf implants. We believe ConforMIS is well positioned to take market share, especially because Medicare and other payors are shifting reimbursement away from a fee-for-service payment model and toward bundled payments. Because patients who receive ConforMIS implants have been shown to recover faster than patients who receive off-the-shelf implants, the total cost of care for these patients should be lower, which, in our view, should drive hospital adoption.
