The brief
- TMINI is an open platform: surgeons choose the implant; it covers about 70% of US knee implants by volume, including Stryker's Triathlon.
- 5,000th procedure in May 2026, five times the volume of a year earlier.
- Zimmer Biomet distributes TMINI with its Persona knee; up to $65M debt facility from Symbiotic Capital (July 2026).
Technical approach
A robot in the surgeon's hand
A wireless handpiece compensates for the surgeon's hand motion to place pins on exactly planned planes, instead of a large floor-standing arm.
Any implant maker's knee
Each implant model gets its own data module and FDA clearance, so hospitals keep their preferred implant supplier.
Cuts planned in 3D beforehand
A CT scan of the knee is turned into a 3D plan that sets where every bone cut goes before surgery starts.
