What ConforMIS does
ConforMIS (Conformis Inc.) developed, manufactured, and commercialized personalized, patient-specific 3D-printed orthopedic implants for knee replacement procedures, using proprietary osseointegrative biomaterials and CT-scan-based design workflows. The company's core technology stack combined 3D printing of osseointegrative materials, proprietary iJig instrumentation, and AI-based planning and design automation tools that translated patient imaging data into custom implant geometries, distinguishing its offering from standardized off-the-shelf knee implant systems. The company sold primarily to orthopedic surgeons and the hospitals and surgical centers where they practiced, distributing directly to healthcare facilities through a field sales motion and surgeon-led adoption channels. Pricing was not publicly disclosed; revenue was generated per implant sold into surgical procedures, making procedure volume and surgeon adoption the primary revenue drivers.
Founded in 2004 in Burlington, Massachusetts, ConforMIS raised over $540 million in disclosed funding across multiple equity and debt rounds from investors including Aeris Capital, AGC Equity Partners, Axel Johnson, Innovatus Capital Partners, and Oxford Finance LLC. The company was publicly traded on Nasdaq under the ticker CFMS and was acquired by restor3d in September 2023, at which point it ceased to operate as an independent entity. Under restor3d, the ConforMIS personalized knee portfolio was combined with personalized foot/ankle and hip solutions to create a broader personalized musculoskeletal reconstruction platform.

ConforMIS competitors and assessment
Company assessmentBroad incumbents
- DePuy Synthes (Johnson & Johnson MedTech): DePuy Synthes, J&J's orthopedic arm, offers the Attune knee system and VELYS robotic-assisted solution. A broad incumbent competing in the same primary knee replacement procedures where ConforMIS personalized implants are used.
- Stryker: Stryker is a global orthopedic major offering knee implants (including Triathlon) bundled with the Mako robotic-assisted surgery platform. Competes with ConforMIS in total knee arthroplasty via a high-volume off-the-shelf-plus-robotic approach rather than patient-specific 3D printing.
- Zimmer Biomet: Zimmer Biomet is one of the largest orthopedic device companies globally, with a broad knee portfolio (Persona, NexGen) and the ROSA robotic platform. A key incumbent competitor in primary and revision knee replacement against which ConforMIS positioned its personalized offering.
- Smith+Nephew: Smith+Nephew offers the Journey and Legion knee systems plus the CORI handheld robotic system. A broad incumbent in knee arthroplasty and a competitor for the same surgeon customers ConforMIS targets with its patient-specific approach.
Direct peers
- restor3d: restor3d is the strategic acquirer of ConforMIS and now the parent company. It offers personalized 3D-printed orthopedic implants across foot & ankle, knee, and hip with AI-based planning and osseointegrative biomaterials — directly comparable technology platform now encompassing the ConforMIS knee line.
Emerging players
- Exactech (now part of TPG-backed entity): Exactech offers the Truliant knee system and Vantage ankle, with personalized instrumentation capabilities. A smaller orthopedic competitor that, like ConforMIS, targets anatomically-matched solutions in joint reconstruction.
- Onkos Surgical: Onkos Surgical focuses on personalized 3D-printed implants and instruments for complex orthopedic oncology and revision arthroplasty. Comparable to ConforMIS in using patient-specific 3D printing and digital planning for musculoskeletal reconstruction.
- Medacta International: Medacta is a Swiss orthopedic company offering knee and hip implants with the MySolutions personalized planning ecosystem. Comparable to ConforMIS in focusing on personalization and surgeon-specific digital workflow, though with a broader product portfolio.
- Materialise NV: Materialise is a Belgium-based 3D printing company with a dedicated medical division producing patient-specific surgical guides, implants, and anatomic models. Directly comparable in providing patient-matched medical 3D printing services and digital surgical planning software.
Others
- Patient Specific Instruments / Symbios (Smith+Nephew): Symbios, originally an independent patient-specific instrumentation company acquired by Smith+Nephew, provided custom 3D-printed surgical guides for knee replacement — historically one of the closest direct comparables to ConforMIS's iJig instrumentation model before consolidation.
