The description mentions "algorithms" for converting sensor outputs to spatial coordinates and providing graphical representation, which is standard for navigation systems and does not inherently indicate AI/ML. There is no mention of learning, training data, or adaptive capabilities typically associated with AI/ML.
No.
The device is a computer-assisted surgical navigation system designed to aid surgeons in accurate implant positioning during knee arthroplasty, not to actively treat a condition.
No
The device is a computer-assisted surgical navigation system used to assist surgeons in determining reference alignment axes and positioning implants/instrumentation during orthopedic surgical procedures, primarily Total Knee Arthroplasty. It facilitates surgical execution rather than diagnosing a condition.
No
The device description explicitly states that the system comprises a "palm-sized computer module and reference sensor" and "reusable instrumentation," including a "reusable reference sensor, and reusable tibial jig." This indicates the presence of hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The KneeAlign™ System with Reference Sensor is a computer-assisted surgical navigation system used during orthopedic surgical procedures (specifically knee arthroplasty). It assists the surgeon in determining anatomical alignment and positioning implants and instrumentation.
- Lack of Biological Sample Analysis: The description clearly states the device is "non-invasive" and utilizes sensors and algorithms to provide positional information and graphical representations. There is no mention of analyzing biological samples from the patient.
Therefore, the KneeAlign™ System with Reference Sensor falls under the category of a surgical navigation or guidance system, not an In Vitro Diagnostic device.

Device Description
The KneeAlign System with Reference Sensor is an innovative non-invasive computer assisted surgical navigation system for use in knee arthroplasty procedures. The KneeAlign System is configured to detect, measure, and display angular measurement changes in a triaxial format. The KneeAlign System with Reference Sensor utilizes a palm-sized computer module and reference sensor to generate positional information in orthopedic procedures providing a sequence of steps for registration of anatomical landmarks, calculation of mechanical axes, and positioning of instruments relative to the mechanical axes. In knee arthroplasty procedures, the device assists the surgeon in establishing the mechanical axis of the tibia, determining the varus/valgus angle and the posterior slope angle of the cutting block relative to tibia. The KneeAlign System with Reference Sensor comprises a single use computer module and reusable instrumentation.
The KneeAlign™ System with Reference Sensor comprises a single use computer module, a reusable reference sensor, and reusable tibial jig. The device utilizes algorithms to convert sensor outputs into spatial coordinates, providing graphical representation of instruments and anatomy on the user display screen.
