Intended Use

The Stryker OrthoMap Precision Knee system, which is comprised of the OrthoMap Precision Knee 5.0 Software and a platform of the NAV3i platform family, is intended as a planning and intraoperative guidance system to enable open or percutaneous image guided surgery. The system can be used for intraoperative guidance where a reference to a rigid anatomical structure can be identified. The system is indicated for conditions of the knee joint in which the use of computer assisted surgery may be appropriate.

Device Story

System provides planning and intraoperative guidance for knee surgery; utilizes wireless optical tracking to display real-time location of surgical instruments relative to patient anatomy. Input: infrared light emitted by active diodes on smart instruments (trackers/pointers) sensed by navigation camera array. Processing: software computes spatial information based on intra-operative anatomy survey of femur and tibia; maps instruments to computed anatomical model. Output: visual display of instrument position/movement relative to target anatomy on monitor. Used in OR by surgeons; supports open or percutaneous procedures. Benefits: enables precise alignment of mechanical axes and implant positioning; reduces reliance on manual estimation. Healthcare providers use visual feedback to guide bone resection and implant placement.

Clinical Evidence

No clinical studies performed. Evidence consists of bench testing, including ASTM F2554-10 accuracy testing, system accuracy verification (± 2 mm, ± 1°), clinical workflow simulation using Sawbones, and functional/safety testing.

Technological Characteristics

Infrared optical active sensing technology; wireless tracking of smart instruments via camera array. Components: computer, navigation camera, IO-Tablet, monitor. Software: OrthoMap Precision Knee 5.0. Standards: ANSI/AAMI ES60601-1, IEC 60601-1-2. Accuracy: ± 2 mm translational, ± 1° rotational.

Indications for Use

Indicated for patients with knee joint conditions requiring surgery where computer-assisted navigation is appropriate.

Indication for Use:

{4}------------------------------------------------

The Stryker OrthoMap Precision Knee system, which is comprised of the OrthoMap Precision Knee 5.0 Software and a platform of the NAV3i platform family, is intended as a planning and intraoperative guidance system to enable open or percutaneous image guided surgery.

The system can be used for intraoperative guidance where a reference to a rigid anatomical structure can be identified.

The system is indicated for conditions of the knee joint in which the use of computer assisted surgery may be appropriate.

### Device Description:

The Stryker OrthoMap Precision Knee system is intended to be used as a planning and intraoperative guidance system to enable open or percutaneous image guided knee surgery. The system uses wireless optical tracking technology to display to the surgeon the intraoperative location of navigated surgical instruments relative to a computed anatomical model of the patient's leg (femur and tibia). The computed model is based on an intra-operative anatomy survey of the leg. The system consists of a Stryker surgical software application (software), which runs on a platform, consisting of a Stryker computer, a navigation camera, an IO-Tablet and a monitor. The Stryker surgical software application interfaces with smart instruments (e.g. patient trackers, instrument trackers or pointers) and several accessories enabling the tracking of surgical instruments.

The Stryker OrthoMap Precision Knee 5.0 software is compatible with the NAV31 Platform Family. The NAV3i platform family is a family of platforms that, when used with a surgical software application, displays patient specific images and/or patient specific anatomical landmark information and tracks the position and movement of surgical instruments in relation to a target anatomical site on a patient. The NAV3i platform family consists of the following three platforms that have been previously cleared independently or with other Stryker surgical software applications:

- Stryker NAV3 Platform
- Stryker NAV3i Platform ●
- Stryker NAVSuite3 Kit

The platforms consist of the following components:

- Stryker computer
- Navigation camera ●
- IO-Tablet ●
- Monitor
- Mobile cart (if applicable) ●

### Performance Data:

The following performance data were provided in support of the substantial equivalence decision:

### Electrical Safety and Electromagnetic Compatibility (EMC) Testing

{5}------------------------------------------------

Electrical safety and EMC testing were conducted on the subject device in accordance with the following standards:

- ANSI/AAMI ES60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and ● A2:2010/(R)2012 (Consolidated Text) Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD) (FDA Rec# 19-4)
- . IEC 60601-1-2:2007: Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests (FDA Rec#19-1)

### Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "MAJOR" level of concern.

### Performance Testing - Bench

The following design verification activities have been performed to ensure the correct functionality of the system as it has been specified:

- ASTM accuracy testing verifying the accuracy performance of the localization and . tracking technology using the standardized test procedure according to ASTM Standard F2554-10.
- . System accuracy testing verifying the specified accuracy of ± 2 mm and ± 1° using a mechanical leg mimicking the patient's anatomy.
- . Clinical workflow testing verifying that all system components (application, computer platform and accessories) are compatible. Complete total knee arthroplasty procedures are simulated using Sawbones mimicking the patient's anatomy.
- Functional testing to ensure that all functional requirements are fulfilled.
- . Safety testing verifying the effectiveness of all risk controls determined in the device risk analysis and in the risk analyses of the platforms.

This strategy ensures the verification of the accuracy, system integration, software algorithms, system functionality, and correct implementation of the risk control measures. All tests have been successfully completed.

### Animal Study

No animal studies were performed to support substantial equivalence.

### Clinical Studies

No clinical studies were performed to support substantial equivalence.

{6}------------------------------------------------

### Substantial Equivalence Rationale:

The intended uses of the subject and predicate devices are similar. The systems are intended as planning and intraoperative guidance systems to enable open or percutaneous computer assisted surgery. Minor modifications were made to the indication for use statement to provide clarification, but do not change the meaning of the indication for use statement.

Both the subject device and the primary predicate device use the same main system components, use similar modes of operation, and use the same localization and tracking technology. Also, both systems use similar accessories (Smart Instruments, Patient Tracker Fixation, Navigated Manual Instruments and other accessories).

The technological characteristics of the subject and predicate device are equivalent. None of the changes alter the operating principle, the control mechanism, the localization and tracking technology, the main system components or the system accuracy performance. The workflow, user interaction, the software architecture and the software features are similar. As demonstrated by the performance testing described above, the subject device continues to meet the same accuracy specifications as the predicate device. Therefore, the differences in technological characteristics to do not raise new questions of safety and effectiveness.

In conclusion, the Stryker OrthoMap Precision Knee system can be found substantially equivalent to the OrthoMap Express Knee system (K153240).

The device comparison table below provides a comparison of the technological characteristics of the subject device to the primary predicate device.
