Zimmer Biomet keeps THINK Surgical's handheld TMINI knee robot for several more years
Zimmer Biomet and THINK Surgical said in a joint press release on Oct 13 that they have extended their Limited Exclusive Distribution and Supply Agreement for several years. Zimmer Biomet will keep selling an exclusive version of the wireless, handheld TMINI robot that works with its Persona Knee System.
Neither company disclosed the length of the extension or any financial terms.
Zimmer Biomet and THINK Surgical said in a joint press release distributed on PR Newswire at 7:30 a.m. EDT on Oct 13 that they have agreed a multi-year extension of their Limited Exclusive Distribution and Supply Agreement. Under the extension, Zimmer Biomet, which is listed in New York and Zurich under ZBH, continues to distribute an exclusive version of THINK Surgical's TMINI Miniature Robotic System that is compatible with Zimmer Biomet's Persona Knee System.
The release gives no length for the extension beyond "multi-year", no start date for the original term and no financial terms. It describes the first term as a successful partnership and says the extension is meant to speed up adoption of the TMINI system with Persona.
What the TMINI is, and why the exclusive version matters
The TMINI is a wireless robot that the surgeon holds in the hand during total knee replacement, rather than a large arm on a floor-standing cart. THINK Surgical describes its robots as open platforms that support implants from several manufacturers. The Zimmer Biomet arrangement is the exception: a customised TMINI that integrates Zimmer Biomet technology and is sold by Zimmer Biomet for its own knee implant.
THINK Surgical chief executive Stuart Simpson said the extension confirms the value the system has delivered to Zimmer Biomet's customers and their patients. Brad Kessler, Zimmer Biomet's president for the Americas in robotics, technology and data, called THINK a valuable partner and said the TMINI meets customer demand for a wireless, handheld robotic system, according to the release.
The release does not cite a regulatory clearance number for the product and tells readers to check product clearance country by country, so the geographic reach of the Persona version is not stated.
MEKAWIRE analysis
We read the renewal as Zimmer Biomet choosing to rent a handheld form factor from a smaller specialist rather than build one, and THINK Surgical accepting a single-brand channel in exchange for a large sales force.
The evidence for the first half is the structure of the deal itself: an implant maker extending an exclusive supply contract instead of letting it lapse after a first term it calls successful. For THINK, the trade-off is clear in its own description. Its pitch to hospitals is implant choice, yet its biggest named channel ties one TMINI version to one implant. The strongest counter-argument is that without terms and volumes nobody outside the two companies can say whether the first term moved meaningful numbers of procedures.

As of Oct 14, 2026
Orthopedic robot developers are thin in our records. Monogram Technologies, which builds knee robots, shows about $17.2 million in disclosed funding through October 2024. THINK Surgical has no verified funding rounds in our database, so its capital position is unknown to us.
Bull case: the extension signals that handheld robots are winning surgeons who would not buy a large arm system, and Persona users become a steady installed base for THINK. Bear case: an exclusive tie to one implant caps TMINI's reach, and a renewal without disclosed volumes may simply preserve the status quo.
Signals to watch: whether Zimmer Biomet quantifies TMINI placements or procedures in its third-quarter 2026 results, whether THINK Surgical announces clearances or distribution deals for other implant brands, and whether the length of the extension appears in any Zimmer Biomet filing.
