Read the full statement (165 words)

TMINI® Miniature Robotic System is indicated as a stereotaxic instrumentation system for total knee replacement (TKA) surgery. It is to assist the surgeon by providing software-defined spatial boundaries for orientation and reference information to identifiable anatomical structures for the accurate placement of knee implant components.

The robotic device placement is performed relative to anatomical landmarks as recorded using the system intraoperatively and based on a surgical plan determined preoperatively using CT based surgical planning tools.

The targeted population has the same characteristics as the population that is suitable for the implant(s) compatible with the TMINI® Miniature Robotic System. The TMINI® Miniature Robotic System is to be used with the following knee replacement system(s) in accordance with the indications and contraindications:

• Enovis™ EMPOWR Knee System®

• Ortho Development® BKS® and BKS TriMax® Knee System

• Total Joint Orthopedics Klassic® Knee System

• United® U2™ Knee Total Knee System

• Medacta® GMK® Sphere / SpheriKA Knee Systems

• Zimmer Biomet Anterior & Posterior Referencing Persona® Knee

Indications for use as stated in the FDA summary.
