Intended Use

The TSolution One® Total Knee Application is intended for use as a device that uses diagnostic images of the patient acquired specifically to assist the physician with preoperative planning and to provide orientation and reference information during intraoperative procedures. The robotic surgical tool, under the direction of the surgeon, precisely implements the presurgical software plan. The preoperative planning software and robotic surgical tool are used as an alternative to manual planning and resecting techniques for the distal femur and proximal tibia preparation in primary total knee arthroplasty (TKA). The TSolution One® Total Knee Application is indicated for orthopedic procedures in which resecting techniques used for the distal femur and proximal tibia may be considered to be safe and effective and where references to rigid anatomical structures may be made. The TSolution One® Total Knee Application is also intended to assist the surgeon in determining reference alignment axes in relation to anatomical and instrumentation structures during stereotactic orthopedic surgical procedures. The TSolution One® Total Knee Application facilitates accurate positioning of TKA implants, relative to these alignment axes. The TSolution One® Total Knee Application is compatible with the following Knee Implant Systems: · Zimmer Persona™ Knee System · Corin Unity Knee System Aesculap Columbus Knee System · DJO Surgical® EMPOWR 3D Knee® System United U2 Knee System

Device Story

System comprises TPLAN (preoperative planning workstation) and TCAT (robotic surgical tool). TPLAN uses patient CT scans to generate 3D bone models; surgeon plans implant position/orientation using library of cleared components. TCAT includes electromechanical arm, control electronics, display, and pendant control. During surgery, system uses pinless point-to-surface registration with mechanical tracking; percutaneous probe contacts bone. Robotic arm implements presurgical plan for bone preparation with submillimeter precision. Two bone motion recovery markers manage registration after bone motion. Surgeon operates system to facilitate accurate TKA implant positioning. Benefits include precise bone resection as alternative to manual techniques.

Clinical Evidence

Bench testing and cadaver model validation performed. Cutting accuracy verification and simulated surgical testing in cadaver models demonstrated that the device met all acceptance criteria and specifications, consistent with predicate performance.

Technological Characteristics

System includes TPLAN workstation and TCAT electromechanical robotic arm. Uses CT scan input for 3D modeling. Registration via pinless point-to-surface mechanical tracking with percutaneous probe. Includes bone motion recovery markers. User controls: keyboard, mouse, and pendant with mechanically latched stop button. Software-driven robotic implementation of preoperative plan.

Indications for Use

Indicated for orthopedic procedures requiring distal femur and proximal tibia resection in primary total knee arthroplasty (TKA) where references to rigid anatomical structures are possible. Compatible with specific knee implant systems (Zimmer Persona, Corin Unity, Aesculap Columbus, DJO EMPOWR 3D, United U2).

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.
