Intended Use
- Severe knee joint pain, loss of mobility, and disability due to: rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis. - Correction of functional deformities. - Post-traumatic loss of knee joint contour, particularly when there is patellofemoral erosion, dysfunction, or prior patellectomy. - Moderate valgus, varus, or flexion trauma. - Knee fractures untreatable by other methods. - Revision surgery where sufficient bone stock and soft tissue integrity are present (For PCK Components and Primary PCK Components only).

Device Description
The Freedom Total Knee System All-Poly Tibial Plate implants have been developed with the desire to expand upon the already clinically successful Freedom® Total Knee System, melding together the best design features of various sub-systems into one. The implants will retain the key benefits of the All-Poly Tibial implant system while leveraging some of the modular, metal-backed systems (K090411, K182574, K243277). Using the All-Poly design, the articular surface, tibial baseplate, and stem are manufactured from a single component. This eliming from modularity, reduces the overall weight and subsidence risk, adds full radiolucency to the tibial implants, and comes at a reduced cost. Like the original All-Poly Implants, these new versions will be manufactured from GUR 1020 (Type 1) UHMWPE per ASTM F648. To enhance the existing All-Poly Implant designs, the stem of these implants is being upgraded to the larger, finned stem/keel design from the modular Freedom® Total Knee System (K090411). This will provide the new All-Poly Tibial implanted stability post-operatively and allow surgeons to use the same instruments/surgical technique as the modular, metal-backed system. This will improve the harmony between the various Freedom® systems and ensure all produce the same strong clinical results.
More Information

No
The 510(k) summary describes a mechanical knee implant system and does not mention any software, algorithms, or AI/ML capabilities. The focus is on material properties, geometry, and mechanical performance.

Yes
The device is a knee replacement system intended to treat severe knee joint pain, loss of mobility, and disability due to various conditions like arthritis and trauma, which are therapeutic indications.

No

The device description clearly states that it is an implant (Total Knee System All-Poly Tibial Plate implants) used for surgical correction of severe knee joint pain and deformities. Implants are therapeutic devices, not diagnostic ones. The "Intended Use/Indications for Use" section lists conditions that the device treats, not conditions it diagnoses.

No

The device description clearly states that the device is an implant manufactured from UHMWPE and includes physical components like a tibial plate, baseplate, and stem. This indicates a hardware medical device, not a software-only one.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device for surgical implantation to treat severe knee joint pain and deformities. This is a therapeutic and structural purpose, not a diagnostic one.
  • Device Description: The description details a physical implant made of UHMWPE, designed to replace or augment parts of the knee joint. This is consistent with a medical device for surgical intervention.
  • Lack of Diagnostic Elements: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
  • Anatomical Site: The device is intended for the knee joint, which is a physical location within the body, not a biological sample.

In summary, the device is a surgical implant for treating knee conditions, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

A series of comparative analyses were completed to evaluate the new Freedom Total Knee System All-Poly Tibial Implants in the scope of the verification and validation testing completed for the predicate devices.

The engineering drawing specifications of the new All-Poly Tibial implants were compared to the equivalent engineering drawing specifications of the predicate systems. This review demonstrated that the new All-Poly Tibial implants were equivalent to their predicate devices in both implant geometry and material. Next, analyses of the mechanical properties of the All-Poly Tibial Baseplate were completed to determine if these new Ultracongruent tibial components would fall within the scope of previously completed verification testing. The new All-Poly Tibial implants do not create a new worst- case for mechanical, cleaning, sterilization, or sterile packaging, and therefore fall within the scope of the equivalent verification testing completed for the predicate devices. Comparisons of the device geometry and articulating surface that the device performance properties, including Range of Motion and Constraint, Component Interlock Strength / Disassembly, Contact Area and Stress, and Wear Resistance are equivalent to the previously cleared predicate devices. Finally, a similar comparative analysis was completed to determine if the new All-Poly tibial implants fall within the scope of previously completed validation testing and confirmed that the implantation process, surgical technique, and implant stability/performance will be identical to the existing predicate device counterparts and that additional clinical simulation or other validation activities are not necessary.

Since the new All-Poly Tibial Implants fall within the scope of all relevant verification testing, the evaluation is acceptable to demonstrate the subject Ultracongruent and Medial Congruents do not raise different questions of safety and effectiveness and are substantially equivalent to the predicate devices.

Device Description Summary

The Freedom Total Knee System All-Poly Tibial Plate implants have been developed with the desire to expand upon the already clinically successful Freedom® Total Knee System, melding together the best design features of various sub-systems into one. The implants will retain the key benefits of the All-Poly Tibial implant system while leveraging some of the modular, metal-backed systems (K090411, K182574, K243277). Using the All-Poly design, the articular surface, tibial baseplate, and stem are manufactured from a single component. This eliming from modularity, reduces the overall weight and subsidence risk, adds full radiolucency to the tibial implants, and comes at a reduced cost. Like the original All-Poly Implants, these new versions will be manufactured from GUR 1020 (Type 1) UHMWPE per ASTM F648.

To enhance the existing All-Poly Implant designs, the stem of these implants is being upgraded to the larger, finned stem/keel design from the modular Freedom® Total Knee System (K090411). This will provide the new All-Poly Tibial implanted stability post-operatively and allow surgeons to use the same instruments/surgical technique as the modular, metal-backed system. This will improve the harmony between the various Freedom® systems and ensure all produce the same strong clinical results.

Intended Use/Indications for Use

  • Severe knee joint pain, loss of mobility due to: heumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis. · Correction of functional deformities.

  • Post-traumatic loss of knee joint contour, particularly when there is patellofemoral erosion, dysfunction, or prior patellectorny.

  • · Moderate valqus, varus, or flexion trauma.

• Knee fractures untreatable by other methods.

« Revision surgery where sufficient bone stock and soft tissue integrity are present (For PCK Components only).

The Freedom Total Knee System, Freedom Stemmed Tibial Components and Freedom PCK Components are indicated for cemented fixation

Indications for Use Comparison

The Indications for use for the All-poly Tibial Plate implants are the K082019 predicate with additions related to use of PCK revision components (K131481) from the Freedom Total Knee System.

Technological Comparison

The new All-Poly Tibial implants are designed to work exactly the same as the existing All-Poly and modular, metal-backed Freedom® system components. The Anterior-Posterior (AP) and Medial-Lateral (ML) profiles are identical, and the care also the same. The All-Poly Tibial implants will come in multiple articular surface types. The Posterior surface is identical to those cleared in K082019, the Ultracongruent articular surface is identical to those cleared in K182574, and the Medial Congruent articular surface is identical to those cleared in K243277. This will provide the surgeons with the full portfolio of Freedom® bearing surfaces without needing to use the modular, metal-backed versions.

Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)

A series of comparative analyses were completed to evaluate the new Freedom Total Knee System All-Poly Tibial Implants in the scope of the verification and validation testing completed for the predicate devices.

The engineering drawing specifications of the new All-Poly Tibial implants were compared to the equivalent engineering drawing specifications of the predicate systems. This review demonstrated that the new All-Poly Tibial implants were equivalent to their predicate devices in both implant geometry and material. Next, analyses of the mechanical properties of the All-Poly Tibial Baseplate were completed to determine if these new Ultracongruent tibial components would fall within the scope of previously completed verification testing. The new All-Poly Tibial implants do not create a new worst- case for mechanical, cleaning, sterilization, or sterile packaging, and therefore fall within the scope of the equivalent verification testing completed for the predicate devices. Comparisons of the device geometry and articulating surface that the device performance properties, including Range of Motion and Constraint, Component Interlock Strength / Disassembly, Contact Area and Stress, and Wear Resistance are equivalent to the previously cleared predicate devices. Finally, a similar comparative analysis was completed to determine if the new All-Poly tibial implants fall within the scope of previously completed validation testing and confirmed that the implantation process, surgical technique, and implant stability/performance will be identical to the existing predicate device counterparts and that additional clinical simulation or other validation activities are not necessary.

Since the new All-Poly Tibial Implants fall within the scope of all relevant verification testing, the evaluation is acceptable to demonstrate the subject Ultracongruent and Medial Congruents do not raise different questions of safety and effectiveness and are substantially equivalent to the predicate devices.
