No
The description focuses on stereotaxic guidance, optical tracking, and displaying anatomical axes based on identified landmarks. There is no mention of AI, ML, or related concepts like image processing for automated analysis or decision support beyond basic tracking and display. The modifications are related to instrument compatibility and corresponding software changes, not advanced analytical capabilities.
No
The device is described as a stereotaxic instrument and image-guidance system designed to assist surgeons in positioning Total Knee Replacement components, not to provide therapy itself.
No.
The device assists in positioning surgical components and determining reference alignment axes during Total Knee Replacement surgery, but it does not diagnose a disease or condition.
No
The device description explicitly states that the system consists of software, a computer workstation, an optical tracking system, surgical instruments, and tracking accessories, indicating it is a hardware and software system, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "stereotaxic instrument to assist in the positioning of Total Knee Replacement components intraoperatively." This describes a surgical guidance system used during a surgical procedure, not a test performed on a sample taken from the body to diagnose or monitor a condition.
- Device Description: The description details a system of software, hardware, and instruments used to track and display anatomical positions and instrument locations during surgery. It does not mention any components or processes related to analyzing biological samples.
- Lack of IVD Characteristics: The information does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in biological samples
- Providing information for diagnosis, monitoring, or screening of diseases or conditions based on sample analysis.
The Navitrack System is a surgical navigation system, which falls under a different regulatory category than IVDs.

Device Description
Identically as in the predicates, the Navitrack System - OS Knee Universal device consists of software, a computer workstation, an optical tracking system, surgical instruments, and tracking accessories, designed to assist the surgeon in the placement of Total Knee Replacement (TKR) components. Tracking devices are incorporated with given surgical instruments, as well as on to fixation bases that attach to each of the femur and tibia, such to allow the ability to track and display to the user their respective positions intra-operatively. The femur and tibia are displayed to the user in the form of their main alignment axes. The alignment axes are determined and recorded intraoperatively by identifying the key anatomical references that are used clinically to align and position the TKR components. The instruments are schematically represented.
The main modifications to the predicates are to incorporate a new set of instruments with universal implant instrument interface features along with corresponding software changes such that the application can be compatible to track a variety of TKR implant lines.

Date Summary Prepared: February 8, 2006
Device Trade Name: Navitrack® System - OS Knee Universal
Device Classification Name: Stereotaxic Instrument (84 HAW); 21 CFR § 882.4560
Predicate Devices:
- Navitrack System -- Optical TKR CT-Less; from Orthosoft Inc; 510(k) # K021760 2) Navitrack® System – S&N Image Free Knee; from Orthosoft Inc; 510(k) # K043536
Device Description:
Identically as in the predicates, the Navitrack System - OS Knee Universal device consists of software, a computer workstation, an optical tracking system, surgical instruments, and tracking accessories, designed to assist the surgeon in the placement of Total Knee Replacement (TKR) components. Tracking devices are incorporated with given surgical instruments, as well as on to fixation bases that attach to each of the femur and tibia, such to allow the ability to track and display to the user their respective positions intra-operatively. The femur and tibia are displayed to the user in the form of their main alignment axes. The alignment axes are determined and recorded intraoperatively by identifying the key anatomical references that are used clinically to align and position the TKR components. The instruments are schematically represented.
The main modifications to the predicates are to incorporate a new set of instruments with universal implant instrument interface features along with corresponding software changes such that the application can be compatible to track a variety of TKR implant lines.
Indications for Use / Intended Use:
The Navitrack® System – OS Knee Universal is indicated for use as a stereotaxic instrument to assist in the positioning of Total Knee Replacement components intraoperatively.
It is a computer controlled image-guidance system equipped with a three-dimensional tracking sub-system. It is intended to assist the surgeon in determining reference

alignment axes in relation to anatomical landmarks, and in precisely positioning the alignment instruments relative to these axes by displaying their locations.
This is identical to the predicates.
Technological Comparisons to the Predicate:
The fundamental scientific technology of the predicates is unchanged. The intended use, the indications, along with the main operating principle and control mechanism, are maintained in the proposed device to perform the same surgery to provide the same image guidance assistance in the placement of TKR orthopedic implants. The main changes from the predicates generally included secondary engineering and software modifications in relation to including instrumentation with universal interface features such that they can attach to, and track, the cutting guides of the implant systems. This is opposed to instruments which were specific to given implants in the predicates. In addition, software modifications were involved with respect to improving the user interface, to improving the joint laxity information for ligament balance assistance, and, in combination with instrument changes, to allowing for instruments with multifaced trackers, and to allowing for calibration and measurement functions being combined into a single instrument.
Performance Data:
Non-clinical tests were performed to assess that no new safety and efficacy issues were raised in the device. These included tests and analyses to verify that the accuracy and performance of the system was adequate for its intended use and not reduced in comparison to the predicates.
Conclusion:
The information and data provided in this 510(k) Premarket Notification established that the Navitrack System - OS Knee Universal Knee device is substantially equivalent to the predicates.
