Overview
Conformis is a medical technology company that pioneered the use of patient-specific, 3D-printed orthopedic implants and instrumentation. Founded in 2004 by Dr. Philipp Lang, the company is headquartered in Billerica, Massachusetts, and was formerly listed on NASDAQ under the ticker CFMS. Conformis developed a proprietary imaging and design process that converts a patient's CT scan into custom-fit knee and hip implants, aiming to improve fit and reduce recovery times compared to off-the-shelf devices. The company's product lines include the iTotal and iDuo knee systems, iUni partial knee, and iHip, as well as patient-specific instrumentation. In 2023, Conformis was acquired by restor3d, a privately held orthopedic technology company based in Research Triangle Park, North Carolina, that specializes in 3D-printed, personalized musculoskeletal implants. Following the acquisition, Conformis operates as part of restor3d, and its website redirects to restor3d.com. The brand continues to be associated with personalized orthopedic solutions, leveraging restor3d's expertise in additive manufacturing and digital health.
History
Conformis was founded in 2004 by Dr. Philipp Lang, a radiologist and entrepreneur, with the goal of improving orthopedic implant fit through patient-specific design. The company developed a proprietary process that uses CT imaging to create a 3D model of a patient's joint, which is then used to design and manufacture custom implants and instrumentation. This approach contrasts with traditional off-the-shelf implants that come in a limited range of sizes. Conformis received FDA clearance for its iUni partial knee in 2007 and for its iTotal total knee in 2011. The company went public on NASDAQ in 2015 under the ticker CFMS. Over the years, Conformis expanded its product line to include the iDuo (a combined partial knee and patellofemoral implant) and iHip, as well as patient-specific instrumentation for total knee arthroplasty. Despite its innovative technology, Conformis faced commercial challenges, including competition from major orthopedic companies and the high cost of personalized implants. In 2023, Conformis was acquired by restor3d, a privately held company specializing in 3D-printed orthopedic implants. The acquisition aimed to combine Conformis's patient-specific imaging and design capabilities with restor3d's expertise in additive manufacturing and digital health. Following the acquisition, Conformis operates as a subsidiary of restor3d, and its products are integrated into restor3d's portfolio of personalized orthopedic solutions.
