The brief

Analyst view
  • 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

As reported
Handheld

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.

Open library

Any implant maker's knee

Each implant model gets its own data module and FDA clearance, so hospitals keep their preferred implant supplier.

CT plan

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.
