What Serf does

SERF (Société d'Etude, de Recherche et de Fabrication) is a French orthopedic implant manufacturer founded in 1973 by André Rambert and headquartered in Décines-Charpieu, France. The company invented the Dual Mobility concept for hip arthroplasty in 1975 through collaboration with Professor Gilles Bousquet, a design that combines two bearing surfaces (small articulation between femoral head and insert, large articulation between insert and cup) to reduce dislocation risk and increase range of motion. SERF's product portfolio spans three segments: hip implants (NOVAE dual mobility acetabular cups, HYPE cups, CHIBF E bipolar cups, HYPE and Libra femoral stems, SAGITTA EVL R revision stems), knee implants (MADISON total knee prosthesis in PS and UC versions, acquired from Implanet in 2021), and extremity/foot implants (F.A.S.T. screws, plates, TOE implants, varisation staples). The company also provides SERF Planning Software, a 2D web-based pre-operative planning tool.

SERF generates revenue primarily through direct sales of orthopedic implants to healthcare establishments in France and Italy, supplemented by an international distribution network covering 25+ countries across Europe, Africa, the Americas, Asia-Pacific, and the Middle-East. The company employs consignment (Dépôt) and loan (Prêt) inventory models at customer sites, with revenue recognized upon implant use. Pricing is quote-based, ex-works Décines-Charpieu, with a minimum order of 70 EUR excluding tax, and includes additional fees for loan services. SERF also generates professional services revenue through the SERF Excellence training platform (webinars, cadaver labs, expert surgeon sessions). The company is certified to ISO 13485:2016, holds CE marking under EU MDR 2017/745, FDA compliance via 21 CFR Part 820, and ANVISA GMP accreditation.

As of March 2024, SERF was acquired by Stryker Corporation to expand Stryker's shoulder replacement portfolio with Dual Mobility Cup technologies. Prior to that, SERF had operated as a subsidiary of the MENIX Group since 2009. The company maintains wholly-owned subsidiaries including SERF Extremity (2014, foot implants), SERF Italy (2019, Pesaro), and SERF Inc. USA (2022, North American market entry). Headcount is reported at 51-100 employees in firmographic data, with the careers page indicating 150+; exact revenue figures are not publicly disclosed.
