Identification
A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

The indications for use, the technical characteristics (manufacturing principle, method of fixation), the packaging and the sterilization process of the new HLS Kneetec System are similar or identical to the predicate devices.
The different technical characteristics of the new HLS Kneetec System compared to the predicate devices are a new design of the tibial tray, a new femoral trochlear groove design with a new patella dome design. The new design of the HLS Kneetec System compared to the predicate HLS Noetos (K0143906) provides a better bone coverage and a greater interchangeability between sizes.

### 10) Non-clinical testing
Non-clinical testing was not necessary to determinate substantial equivalence between the new HLS Kneetec System and the cited predicate devices about:
- The indications for use of the new HLS Kneetec System are identical to the indications for use of the predicate HLS Noetos System (K013906) and are very similar with the other predicates the PFC Modular Plus Offset Tibial Tray (K984158), the NexGen Complete Knee solution Legacy Posterior Stabilized (K991581) and the AGC Total Knee System (K833021, K912245, K984054).
- . The intended use of the new HLS Kneetec System are identical to the intended use of predicates HLS Noetos System (K013906), PFC Modular Plus Offset Tibial Tray (K984158), NexGen Complete Knee solution Legacy Posterior Stabilized (K991581) and AGC Total Knee System (K833021, K912245, K984054).
- -The raw materials of the new components of the HLS Kneetec System are identical to the raw materials of predicate HLS Noetos System (K013906).
- -The fixation method of the new components of the HLS Kneetec is identical to the fixation method of the predicate components of the HLS Noetos (K013906), the PFC Modular Plus Offset Tibial Tray (K984158), the NexGen Complete Knee solution Legacy Posterior Stabilized (K991581) and the AGC Total Knee System (K833021, K912245, K984054).1379, and K091751).
Non clinical testing was necessary to determinate substantial equivalence between the new HLS Kneetec System and the cited predicate devices about:
- -The new design of the femoral component:
A contact area stress / pressure test was performed to compare contact pressure on UHMWPE tibial insert between the HLS Kneetec size 2 and the predicate HLS Noetos size 1 (K013906- Equivalent size) at each flexion angle.
The acceptance criteria is: the contact area stress and the contact pressure between the new HLS Kneetec size 2 and the predicate HLS Noetos size 1 (K013906- Equivalent size) must be equivalent.
Results of verification: there is no significant difference between the HLS Kneetec size 2 and the predicate HLS Noetos size 1 (K013906), the contact area stress /pressure is equivalent between the two prostheses.
So, the HLS Kneetec size 2 and the cleared HLS Noetos size 1(K013906) are equivalent.
Constraint test was performed to determine the constraint forces in anterior-posterior displacement, medial-lateral displacement and internal-external rotation between the HLS Kneetec size 2 and the predicate HLS Noetos size 1 (K013906 - Equivalent size) according to ASTM F1223.
The acceptance criteria is: load displacement curves must be equivalent to the predicate device HLS Noetos (K013906).
Results of verification: there is no significant difference between the HLS Kneetec size 2 and the predicate HLS Noetos size 1 (K013906), the frame of load displacement curves is equivalent between the two prostheses.
So, the HLS Kneetec size 2 and the cleared HLS Noetos size 1(K013906) are equivalent.

### The new tibial tray design:
A fatigue test on the fixed Kneetec tibial tray was done to validate the fixed tibial tray of the HLS Kneetec following existing standards (Fatigue tests: ASTM F1800:2007 & NF ISO 14879-1:2000). The acceptance criteria is: the fixed tibial tray tested must resist to 10 millions of cycles without any damages.
Results of verification: five fixed tibial trays have been tested during 10 millions of cycles under maximum load of 237daN. No damage nor ruptures have been noted on the five fixed tibial trays. So, the new tibial tray of the HLS Kneetec is conformed to the standards.
- -The new femoral trochlear groove design with a new patella dome design:
A comparative study was done to verify that the new design of the trochlea has equivalent congruence with the new patella. We have conducted a comparative test versus the marketed predicate device HLS Noetos size 1(K013906) on the worst case component HLS Kneetec size 2 (equivalent size) to study the tracking of the patella under quadriceps motion.
The acceptance criteria is: the contact area and trajectories must be equivalent to the predicate device HLS Noetos (K013906).
Results of verification: for the HLS Kneetec and the predicate HLS Noetos (K013906) the principle is the same, the tracking of the patella is steady when moving the quadriceps in each position.
So, the design of the patella and the patella groove between the new HLS Kneetec and the cleared HLS Noetos (K013906) are equivalent.
Results of engineering studies referenced in this 510(k) submission demonstrate the proposed HLS Kneetec System device is substantially equivalent to the predicate devices.
### 11) Substantial equivalence conclusion
Based upon this comparative study, substantial equivalence of the new HLS Kneetec System to the already cleared components of the predicates can be demonstrated on the following grounds, according to the FDA's Guidelines for Substantial Equivalence Decision Making Process:
- The components of the HLS Kneetec System are compared to the predicate devices. ।
- The components of the HLS Kneetec System have the same intended use as the HLS Noetos System, the PFC Modular Plus Offset Tibial Tray, the NexGen Complete Knee solution Legacy Posterior Stabilized and the AGC Total Knee System and very similar indications for use.
- Major technological characteristics are equivalent between the HLS Kneetec System and the predicate । devices:
- ﮯ Equivalence of general features
- -Equivalent polyethylene thickness
- -Equivalent materials
- -Equivalent means of fixation
- -Equivalent prosthetic dimensions
Therefore, in light of the above information, the company believes that the components of the HLS Knetter System may be cleared via the 510(k) notification process for use as a total knee prosthesis.

The logo has a slightly distressed or textured look, suggesting it may be from a vintage or worn design. The overall impression is simple, clean, and potentially representative of a brand or organization with a name starting with 'T'.

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.
