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 as 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.
Device Story
System comprises TPLAN workstation and TCAT robotic arm; assists surgeons in primary total knee arthroplasty (TKA). TPLAN uses patient CT scans to create 3D bone models; surgeon plans implant position/orientation. TCAT, an electromechanical arm, executes the plan via submillimeter bone preparation. Used in surgical settings; operated by surgeons. Registration uses pinless point-to-surface technique with percutaneous probe; bone motion recovery markers maintain registration. System provides precise implant positioning relative to anatomical axes. Benefits include increased surgical efficiency, consistency, and accuracy compared to manual techniques.
Clinical Evidence
Bench testing only. Performance verified via cutting accuracy testing, electromagnetic compatibility/electrical safety testing per IEC standards, and simulated surgical cadaver model validation. Biocompatibility testing performed per ISO 10993-1:2009 for new patient-contacting materials. All testing met pre-defined acceptance criteria equivalent to the predicate device.
Technological Characteristics
Stereotaxic instrument; electromechanical robotic arm (TCAT) and 3D planning workstation (TPLAN). Inputs: CT scan data. Registration: Pinless point-to-surface with percutaneous probe. Connectivity: Keyboard, mouse, pendant control with mechanical stop button. Biocompatibility: ISO 10993-1:2009 compliant. Software: Preoperative planning and robotic control algorithms.
Indications for Use
Indicated for patients undergoing primary total knee arthroplasty (TKA) requiring distal femur and proximal tibia preparation where resecting techniques are safe and effective and rigid anatomical references are available.
Regulatory Classification
Identification

device and the predicates is that the new device incorporates a series of incremental changes in the hardware and software that enhance system efficiency and consistency, enhance the flexibility and ease of use of the system, and improve the cybersecurity and aesthetics of the system. None of these changes either individually or in the aggregate alter the intended use, indications for use, design, materials, technology or operational principles of the TSolution One Total Knee Application.
The Indications for Use of the new device and its predicate are identical.
The results of the analysis demonstrate that any risks identified have been mitigated to acceptable levels and no new clinical hazards arise as a result of the changes. Additionally, the modifications made to the predicate device do not raise any new questions of safety or effectiveness or increase the overall risk profile of the device.
Performance testing to verify the cutting accuracy of the subject device was conducted following similar test methods and acceptance criteria to those used for the predicate device. Electromagnetic Compatibility and Electrical Safety testing met the requirements of applicable IEC standards. Validation testing, with methods and acceptance criteria similar to that used for the predicate device, was conducted using simulated surgical testing in a cadaver model and all test criteria were met. Biocompatibility Testing performed according to the ISO 10993-1:2009 standard was completed on any new patient contacting materials. All of this testing demonstrated that the TSolution One® Total Knee Application met the test criteria and specifications of the predicate device.
