CASTEL SAN PIETRO, Switzerland, November 02, 2026 – Medacta Group SA ("Medacta," SIX: MOVE) today announces the full commercial release of the Mfinity™ Femoral System in the United States. Designed to accommodate diverse patient anatomies and MIS approaches, Mfinity combines a comprehensive range of stem options with streamlined instrumentation to promote an efficient and reproducible surgical workflow in total hip replacement. Its U.S. launch follows more than one year of successful limited market use in selected centers of excellence. Outside the U.S., the first surgical cases were performed in Japan in September 2026, and clinical studies supporting future registrations are underway in Australia and Europe.
"The main objective when designing Mfinity was flexibility without complexity. The system offers surgeons multiple stem options, including collared, non-collared, and long versions, with proportional sizing and offset for the patient's anatomy, so they can choose the design that best matches their patient and surgical needs," said James Dowd, MD, Virginia Beach, Virginia, USA.
The Mfinity Femoral System features a metaphyseal-filling stem available in collared and collarless versions, with progressive neck length and collar variation across stem sizes to optimize proper restoration of hip biomechanics. Mfinity™ L completes the system, offering a longer ream-and-broach cementless option optimized for surgeons who prefer this design. A cemented version is expected to be available in 2027, subject to regulatory clearance in the relevant markets.
Drawing on Medacta's MyBody[1] database of thousands of computed tomography (CT) scans, the stem was fine-tuned to fit a wide spectrum of femurs, while its reduced distal geometry makes it particularly suitable for narrow femoral anatomies, including Dorr Type A. Its design also facilitates implantation in minimally invasive approaches, and Medacta's MectaGrip proximal coating aims to enhance both initial and long-term stability.
To enhance OR efficiency, the Mfinity instrumentation allows surgeons to use cementless and cemented stems with a single tray, enabling a seamless intraoperative conversion between the two fixation options without opening an additional instrument set. Modular instruments reduce the tray footprint, making the system well-suited to ambulatory surgery centers (ASCs).
Mfinity can be used with the MyHip® digital suite and with NextAR™ Hip, part of the MySolutions™ Personalized Ecosystem, which integrates 3D preoperative planning with intraoperative guidance and verification tools. Through the M.O.R.E. Institute, Medacta supports the adoption of Mfinity with structured training and hands-on courses, drawing on the experience gathered during the limited market release. Medacta is committed to advancing solutions in hip replacement that address the individual needs of both surgeons and patients, so that more patients may benefit from personalized surgical care and return to an improved quality of life.
The Mfinity Femoral System will be presented at the 2026 American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting, November 5–8, 2026, in Dallas, Texas, USA, where the system and Medacta's full hip portfolio will be on display at Booth #826.
