### 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.
Image /page/4/Picture/22 description: The image shows a logo with a stylized letter 'T' inside a hexagon. The 'T' is constructed from geometric shapes, giving it a modern and abstract appearance. 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'.
