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 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) ●
AI/ML Overview

This document is a 510(k) summary for the Stryker OrthoMap Precision Knee system. It does not describe a study that validates AI performance, but rather outlines the performance criteria and testing for a computer-assisted surgical guidance system. Therefore, some of the requested information regarding AI-specific studies (e.g., MRMC studies, training set details) will not be available.

Here's an analysis of the provided text for the requested information:
