The summary describes a computer-assisted surgical navigation system that uses positional information and pre-defined steps for registration and calculation. There is no mention of AI, ML, image processing, or any learning or adaptive capabilities. The performance studies focus on hardware, sterilization, usability, and accuracy testing against mechanical fixtures and models, not on the performance of an AI/ML algorithm.
No.
The device is a computer-assisted surgical navigation system designed to assist surgeons during orthopedic procedures by providing guidance for implant positioning and alignment, rather than directly treating a condition or restoring health.
No
The device is described as a "computer-controlled system intended to assist the surgeon in determining reference alignment axes" and "facilitates the accurate positioning of implants." It provides "positional information" and calculates mechanical axes for instrument positioning. This description indicates a surgical navigation and assistive tool, not a device used to diagnose a medical condition.
No
The device description explicitly states it comprises a "single use computer module and reusable instrumentation" and mentions "System hardware verification/validation testing". This indicates the device includes hardware components beyond just software.
Based on the provided information, the OrthAlign Plus® System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- OrthAlign Plus® System Function: The description clearly states that the OrthAlign Plus® System is a computer-assisted surgical navigation system. Its purpose is to assist the surgeon during orthopedic surgical procedures by providing guidance and measurements related to anatomical structures and instrumentation. It does not analyze biological specimens.
- Intended Use: The intended use is to assist the surgeon in determining reference alignment axes and positioning implants during surgery. This is a surgical aid, not a diagnostic test performed on a sample outside the body.
- Device Description: The description focuses on the system's components (computer module, sensor) and how it generates positional information during surgery. There is no mention of analyzing biological samples.
Therefore, the OrthAlign Plus® System falls under the category of a surgical navigation or guidance system, not an In Vitro Diagnostic device.

TECHNICAL CHARACTERISTICS (COMPARED TO PREDICATE):
The OrthAlign Plus® System was cleared under K140331. The OrthAlign Plus® System comprises a single use computer module, a reusable reference sensor, a reusable femoral jig, a reusable tibial jig, a reusable posterior hip jig and a reusable anterior hip jig. The device utilizes algorithms to convert sensor outputs into spatial coordinates, providing graphical and numerical representation of instruments and anatomy on the user display screen. The OrthAlign Plus® System is being updated to include navigation functionality for unicompartmental knee arthroplasty, tibial transverse resections, as in the predicate device Aesculap OrthoPilot Next Generation (K141694). All other features and principles of operation remain unchanged.
PERFORMANCE DATA:
Device performance testing confirms that the OrthAlign Plus® System can be used according to its intended use. The OrthAlign Plus® System has been verified and validated according to OrthAlign's procedures for product design and development. Performance testing addressed only the added Unicompartmental instruments and surgical procedure steps. Performance testing included:
- . System hardware verification/validation testing to ensure the instruments meet their mechanical requirements.
- Instrumentation cleaning, sterilization and shipping validations for the specified processes.
- . Navigation device sterilization, packaging, shelf life, environmental conditions and shipping validations for the specified ranges of conditions involved in each process. (Summary data for the identical predicate device is referenced.)
- System components biocompatibility assessment per ISO 10993-1 (2009). ●
- Customer requirements / usability validation in cadaver with an advising surgeon to . validate the system meets design input requirements for its functions in a simulated use environment.
- . System accuracy testing: bench testing with mechanical fixtures and foam models to verify navigated resection plane angular and depth accuracy.
This testing regime demonstrates that the subject device is as safe and effective as the predicate devices. This testing regime demonstrates that the subject device is substantially equivalent to the legally marketed predicate devices, for its intended use in the accurate navigation of tibial resection planes in unicompartmental knee arthroplasty.
The information provided by OrthAlign in this 510(k) application confirms that the OrthAlign Plus® System is substantially equivalent to predicate devices such as the OrthAlign Plus® System (K140331) and Aesculap OrthoPilot Next Generation (K141694).

BASIS FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE:
A technological comparison and bench and cadaver testing demonstrate the substantial equivalence of the OrthAlign Plus® System to the predicate devices.
The subject device is identical to the predicate OrthAlign Plus® System (K140331), with the following exceptions:
- . The subject device allows for the navigation of tibial resection planes in unicompartmental knee arthroplasty.
The subject device is substantially equivalent in terms of unicompartmental knee arthroplasty function to the predicate device Aesculap OrthoPilot Next Generation (K141694).
