Device Description

The NEO Total Knee System was cleared for marketing in April 2012, under 510(k) #K120313. The predicate knee system includes a cruciate retaining (CR) femoral component design, tibial trays, CR tibial inserts for use with intact posterior cruciate ligament(PCL), and patellar components. The subject 510(k) adds ultra congruent (UC) tibial inserts for use when the PCL is sacrificed. There are no changes to materials or to system component size offering.
The Neo Knee System CR femoral components, when used with the mating Neo Knee System CR and UC articular surfaces, are designed to achieve flexion at high angles and provide a clinical ROM up to 150 degrees.

AI/ML Overview

The provided document is a 510(k) summary for the NEO Total Knee System - Line Extension. This document does not describe a study involving an AI/CADeX device. Instead, it describes a medical device (a knee implant) and its performance through mechanical and material testing, not a clinical or comparative effectiveness study involving human readers or AI.

Therefore, many of the requested categories in the prompt do not apply to this document. I will answer the questions that can be addressed based on the provided text, and explicitly state when a question is not applicable.

Acceptance Criteria and Reported Device Performance

The acceptance criteria for this device are implicitly tied to demonstrating "substantial equivalence" to legally marketed predicate devices. This is achieved by showing that the new components (ultra congruent tibial inserts) perform comparably to or within acceptable limits for a total knee replacement system. The performance criteria are related to the mechanical and material integrity of the implant components.

Acceptance Criteria (Implicit from Performance Testing)Reported Device Performance
Material Compliance: Materials used are safe and comply with applicable implantable materials standards.The metal and the standard UHMWPE material are the same as used in the predicate Neo Total Knee System and comply with applicable implantable materials standards.
Mechanical Strength & Durability (Fatigue, Locking Mechanism): Tibial tray fatigue strength and insert locking mechanism strength are adequate for in vivo loading.New testing submitted in this 510(k) or previously submitted in K120313 evaluated tibial tray fatigue strength and insert locking mechanism strength. The testing confirms the system is capable of withstanding expected in vivo loading.
Femorotibial & Patellofemoral Kinematics/Constraint: Appropriate range of motion and constraint for femorotibial and patellofemoral joints.Testing evaluated femorotibial range of motion, femorotibial range of constraint, and patellofemoral range of constraint. The Neo Knee System CR femoral components, used with mating CR and UC articular surfaces, are designed to achieve flexion at high angles and provide a clinical ROM up to 150 degrees.
Contact Mechanics (Area/Stress): Femorotibial and patellofemoral contact areas and stresses are within acceptable limits.Testing evaluated femorotibial contact areas/contact stress and patellofemoral contact area and contact stress. The testing confirms the system is capable of withstanding expected in vivo loading.
UHMWPE Characterization: The UHMWPE material properties are appropriate.Characterization of the UHMWPE was performed. The testing confirms the system is capable of withstanding expected in vivo loading.
Substantial Equivalence: Overall device is substantially equivalent to predicate devices based on design, materials, and performance.The NEO Total Knee System is considered substantially equivalent to the predicate devices due to sharing the same indications for use, materials, manufacturing methods, and similar design, technological, and performance characteristics as the predicate Neo CR Knee System and other cited predicate devices.

Study Proving Device Meets Acceptance Criteria:

The study referenced is a series of "Performance Testing" and a comparison of "Technological Characteristics" to predicate devices. This is a non-clinical, benchtop, and analytical comparison study as typically used for 510(k) submissions for medical devices like implants.

  1. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

    • Sample Size: Not specified in the document. For benchtop mechanical testing, typical sample sizes might be N=5 or N=10 per test condition, but this is not mentioned.
    • Data Provenance: Not specified, but likely from laboratory testing conducted by the manufacturer or a contracted lab. The terms "retrospective" or "prospectively" do not apply to this type of mechanical testing.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

    • Not applicable. This submission describes the mechanical and material performance of an orthopedic implant, not a diagnostic device that requires expert interpretation for a ground truth. The "ground truth" here is the physical measurement of performance against established standards or predicate device performance.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • Not applicable. As above, this does not involve human interpretation or adjudication for a diagnostic task.
  4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    • Not applicable. No MRMC or AI study was performed. This is a 510(k) for a physical implant, not an AI/CADeX device.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not applicable. No algorithm or AI device is described.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

    • The "ground truth" for this type of device is based on engineering and material science principles, established mechanical testing standards (e.g., ISO or ASTM for implants), and performance data from legally marketed predicate devices. The goal is to demonstrate that the new component (UC tibial inserts) performs equivalently or acceptably within the established parameters for total knee systems.
  7. The sample size for the training set:

    • Not applicable. There is no "training set" as this is not an AI/machine learning device.
  8. How the ground truth for the training set was established:

    • Not applicable. As there is no training set mentioned, this question does not apply.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.

(a)
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).(b)
Classification. Class II.
