Zimmer Biomet Holdings, Inc., a global leader in medical technology and musculoskeletal healthcare, has formally announced the extension of its exclusive distribution agreement with Think Surgical, Inc., a pioneer in the development of miniature handheld robotic systems for orthopedic surgery. This multi-year extension ensures that Zimmer Biomet remains the sole distributor of a specialized version of Think Surgical’s TMINI Miniature Robotic System, specifically designed for use with Zimmer Biomet’s flagship Persona Knee system. The move signals a deepening commitment to a diversified robotic portfolio, aiming to capture a broader segment of the orthopedic surgeon market by offering flexibility in both hardware and surgical planning methodologies.
The partnership comes at a critical juncture for the orthopedic industry, as major players race to integrate digital health solutions and robotic assistance into the operating room. By securing an extended agreement for the TMINI system, Zimmer Biomet is positioning itself to address specific surgeon preferences that its existing ROSA Robotics platform may not fully cover. While ROSA remains a cornerstone of Zimmer Biomet’s technological ecosystem, the TMINI provides a portable, handheld alternative that appeals to surgeons operating in space-constrained environments or those who prefer a CT-based workflow.
Strategic Rationale and Executive Insights
The decision to double down on the TMINI distribution was driven by a clear understanding of market segmentation. During an earnings call in late 2024, Zimmer Biomet CEO Ivan Tornos outlined the strategic logic behind maintaining two distinct robotic offerings. Tornos emphasized that the orthopedic market is not monolithic; different surgeons have varying preferences for preoperative planning and intraoperative execution. Specifically, Tornos noted that the TMINI system is highly attractive to clinicians who favor Computed Tomography (CT) scanning capabilities.
CT-based planning allows for a highly detailed, three-dimensional view of the patient’s anatomy before the first incision is made. This contrast with image-less systems or those relying on 2D X-rays provides a level of preoperative precision that many surgeons find indispensable for complex total knee arthroplasty (TKA). According to Tornos, the inclusion of both ROSA and TMINI in the company’s catalog was a primary driver of the record-breaking capital sales Zimmer Biomet recorded in the second quarter of 2024. By offering a "broadest and most flexible" portfolio, Zimmer Biomet aims to eliminate barriers to adoption, ensuring that regardless of a surgeon’s technical preference, there is a Zimmer-compatible robotic solution available.
Brad Kessler, President of Americas for Robotics, Technology, and Data at Zimmer Biomet, echoed these sentiments. He stated that the TMINI system specifically addresses a growing demand for wireless, handheld robotics that do not sacrifice the precision of larger, console-based systems. Kessler framed the relationship with Think Surgical as a vital component of Zimmer Biomet’s overarching mission to provide data-driven, personalized surgical experiences through the Persona Knee system.
Technological Deep Dive: The TMINI System and Persona Integration
The TMINI Miniature Robotic System represents a significant departure from the traditional "large-format" robots that have dominated the orthopedic landscape for the past decade. Unlike systems that require a bulky robotic arm attached to a large cart, the TMINI is a wireless, handheld device that assists the surgeon in performing precise bone resections. It compensates for hand tremors and provides real-time feedback to ensure that the bone cuts align perfectly with the preoperative plan.
The exclusive version distributed by Zimmer Biomet is calibrated specifically for the Persona Knee. The Persona system, often referred to as "The Personalized Knee," is designed to provide a more natural fit for patients by offering a vast array of component sizes and shapes that mimic human anatomy more closely than traditional implants. When the precision of the TMINI robot is applied to the anatomical accuracy of the Persona implant, the result is a surgical procedure that is highly tailored to the individual patient’s morphology.
The TMINI’s workflow is centered on a CT-based 3D plan. Before the surgery, a CT scan of the patient’s leg is uploaded to the Think Surgical software, where the surgeon can virtually position the Persona components to optimize alignment and ligament balance. In the operating room, the handheld robot "knows" the plan and guides the surgeon’s tools to execute the cuts with sub-millimeter accuracy. This workflow is particularly appealing to surgeons who want the reassurance of a pre-validated plan before entering the sterile field.
Think Surgical’s Growth and Commercial Evolution
While Zimmer Biomet handles the exclusive distribution for the Persona-integrated version of the TMINI, Think Surgical has been aggressively scaling its own operations and dual-channel commercial strategy. The company reached a major milestone in May 2024, when the TMINI system was used in its 5,000th clinical procedure. This milestone served as a proof of concept for the reliability and surgeon acceptance of handheld robotics in a field long dominated by heavy machinery.
Following this clinical success, Think Surgical secured $65 million in growth capital in July 2024. The funding round was intended to accelerate the commercial launch of the TMINI system across a wider array of implant brands. Unlike many robotic companies that "lock" their hardware to a single brand of implants, Think Surgical operates on an open-platform philosophy. According to the company, the TMINI is currently compatible with approximately 70% of the total knee implants available on the market.
To lead this commercial expansion, Think Surgical appointed Rick McDowell as Vice President of Sales in September 2024. McDowell, a veteran in the medical device industry, is tasked with managing the national sales organization and navigating the complexities of the dual-channel strategy. This strategy involves partnering with major manufacturers like Zimmer Biomet for exclusive integrations while simultaneously selling a "universal" version of the TMINI to hospitals and surgical centers that use multiple different implant brands.
The Competitive Landscape of Orthopedic Robotics
Zimmer Biomet’s move to extend its deal with Think Surgical is a tactical response to the intensifying competition in the "Big Four" of orthopedics: Stryker, DePuy Synthes (Johnson & Johnson), Smith & Nephew, and Zimmer Biomet.
Stryker currently holds a dominant position in the market with its Mako system, which also utilizes a CT-based planning workflow. By offering the TMINI, Zimmer Biomet provides a direct alternative to Mako that is more portable and potentially more cost-effective for smaller facilities. Meanwhile, Johnson & Johnson’s DePuy Synthes is pushing its Velys Robotic-Assisted Solution, and Smith & Nephew continues to market its handheld CORI Surgical System.
The shift toward handheld and portable robotics reflects a broader trend in the United States healthcare system: the migration of total joint replacements from traditional hospitals to Ambulatory Surgery Centers (ASCs). ASCs typically have smaller operating rooms and more limited capital budgets than large hospitals. A massive robotic console can be difficult to maneuver in these settings and represents a significant capital expenditure. In contrast, a handheld device like the TMINI is easily stored, requires minimal setup time, and carries a lower price point, making it an ideal fit for the high-volume, efficiency-driven environment of an ASC.

Broader Impact and Industry Implications
The extension of this partnership underscores a significant shift in how medical device giants approach innovation. Rather than relying solely on internal R&D, companies like Zimmer Biomet are increasingly looking toward agile, specialized tech firms like Think Surgical to fill niche gaps in their portfolios. This "ecosystem" approach allows larger firms to remain competitive across all market segments without the lead time required to develop every technology in-house.
For the surgical community, the availability of the TMINI for the Persona Knee system means more choices. Surgeons are no longer forced to choose between a specific implant they like and a specific robotic workflow they prefer. By decoupling the robot from a "one-size-fits-all" mentality, Zimmer Biomet is fostering an environment where technology adapts to the surgeon, rather than the surgeon adapting to the technology.
From a financial perspective, the continued success of the TMINI-Persona combination is expected to bolster Zimmer Biomet’s "S.E.T." (Sports Medicine, Extremities, and Trauma) and Knee segments. As robotic-assisted surgery becomes the standard of care for knee replacements, having a versatile hardware lineup is essential for maintaining and growing market share.
As the multi-year agreement moves forward, the industry will likely watch for further integrations, perhaps extending into hip replacements or other orthopedic applications. For now, the focus remains on the knee, where the combination of Think Surgical’s miniature robotics and Zimmer Biomet’s anatomical implants is setting a new benchmark for precision and flexibility in the operating room. The partnership stands as a testament to the power of collaborative innovation in the quest to improve patient outcomes and streamline the delivery of orthopedic care.
