Name of Device: kneeEOS Classification Name: Picture Archiving and Communication System (21 CFR 892.2050) Regulatory Class: II Product Code: LLZ
## Predicate Device
TraumaCad Release 2.0 (K073714) by ORTHOCRAT LTD.
## Intended Use/Indications for Use
kneeEOS is a software indicated for assisting orthopedic surgeon in preoperative planning of knee orthopedic surgery. The software allows for overlaying of 3D/2D implants models on radiological images EOS based and 3D reconstruction of bones, and includes tools for performing measurements on the images or 3D model of bones, and for selecting and positioning the implant model. Clinical judgments and experience are required to properly use the software.
## Device Description
kneeEOS 1.0 allows surgeons to perform preoperative surgical planning of total knee arthroplasties. The software provides surgical tools to analyze preoperative data, to set the resection levels, to position and size the femoral and tibial components and to evaluate the final alignment of the leg. The images displayed are x-rays from EOS System (K152788) and 3D model of the knee from sterEOS Workstation (K160914). kneeEOS also displays preoperative parameters and updated values of these parameters after planning. kneeEOS is accessible on any computer via ONEFIT Management System (Class I device - Product code LMD - 510(k) Exempt) that provides a secure internet interface and storage through authentication mechanisms.
{4}------------------------------------------------
## Comparison of Technological Characteristics with the predicate device
Preoperative planning for knee surgery is the technological principle for kneeEOS and one of the possibilities offered by the predicate. The aim for these software is to provide to the surgeon realistic tools for simulating total knee arthroplasty.
kneeEOS 1.0 (ONEFIT medical, Inc.) and its predicate TraumaCad 2.0 (Orthocrat, Ltd.) are based on the same following technological elements:
- Access to the software is secured and limited only to surgeons because personal data are stored in those software and surgical experience is required.
- Use of x-ray images and preoperative parameters calculated from the patient's anatomy.
- Use of the workflow to guide the surgeon through the steps of planning: observation, analysis and action.
- An interface that allows for the maximum amount of information (including images) and tools, visible simultaneously on the same page.
- Tools for improve visualization, to perform measurements, to choose, size and position implants, and to adjust the alignment of the leg.
- Display values of preoperative parameters and updated values after planning.
The only differences between kneeEOS and its predicate are:
(1) kneeEOS claims compliance with standards EN ISO 14971:2012, IEC 62304:2006 and EN 62366:2008.
(2) Software and hardware minimum requirements for kneeEOS.
(3) kneeEOS input data comprise a 3D model of the knee.
(4) kneeEOS exports a PDF planning report.
(5) kneeEOS displays preoperative and planned values of parameters.
These differences do not present any new questions of safety or effectiveness because:
(1) These international standards are or have been recognized by the FDA. The standard on ability has recently been replaced by a new version, currently recognized by the FDA. However, the two versions claim similar principles on the development of the interface. Despite the lack of information on the subject for the predicate, there is no safety or efficiency question created by this difference, because these standards have also been used in the development of the latest FDA-approved software of ONEFIT medical: spineEOS (see Appendix [42] K160407_spineEOS). These three standards are intended to help reduce risk and errors in the software design.
(2) These requirements are not disproportionate to the computers currently on the market.
(3) This 3D model reconstruction is performed by sterEOS Workstation (K160914), which is a medical device already cleared by the FDA. All indications of use and operating procedures of sterEOS Workstation are respected. The software kneeEOS uses the sterEOS Workstation output data as input data without any prior modification.
(4) Both software allow to generate a report which contains all data from the planning. The difference lies in the format of generated reports (PDF/HTML): Most web browsers up to date include a PDF Reader and this format has the advantage of being more protected aqainst any changes that HTML page. This difference does not raise questions about safety or effectiveness in comparison to TraumaCad. All the information contained in this report can be found in the software. The generation of a planning report is also an available feature in kneeEOS (K160407).
{5}------------------------------------------------
(5) TraumaCad does not have distinct preoperative / planned steps; images are simply displayed and the user can perform measurements on the x-rays (preoperative measurements) or on templates superimposed on x-rays (planned parameters). In kneeEOS, these values (preoperative and after planning) are automatically displayed in the left column and on the xrays but the same information can be extracted from both software. These differences do not raise questions about safety or effectiveness in comparison to TraumaCad because kneeEOS measurements are calculated from anatomical points, which are positioned with sterEOS Workstation (K160914).
kneeEOS has the same intended use and similar indications, technological characteristics, and principles of operation as its predicate device. The minor technological differences between the kneeEOS and its predicate device raise no new issues of safety or effectiveness.
#### Performance Data
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 was considered as a "moderate" level of concern, since a failure or latent design flaw could directly result in minor injury to the patient or operator, or could indirectly result in minor injury to the patient or operator through incorrect or delayed information or through the action of a care provider.
#### Conclusions
The device has the same intended use, and similar indications for use, technological characteristics, and principles of operation as its predicate device. The minor differences between the device and its predicate device raise no new issues of safety or effectiveness. Performance data demonstrate that the kneeEOS is as safe and effective as its predicate TraumaCad Release 2.0 (K073714) and, thus, is substantially equivalent.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
