The provided document is a 510(k) premarket notification for the VEGA Knee System® and Columbus Total Knee System, specifically regarding the introduction of All Poly Tibia posterior stabilizing and cruciate retaining implants with an optional centralizer. It describes the device, its intended use, and its substantial equivalence to previously marketed devices. However, the document does not contain acceptance criteria for device performance or a study proving that the device meets such criteria.

Instead, it focuses on demonstrating substantial equivalence to predicate devices by addressing technological characteristics and manufacturing processes. The "Performance Data" section briefly mentions:

• A risk analysis.
• Biomechanical testing.
• A comparison evaluation of wear.
• Biocompatibility of X-ray markers.
• Validation and verification of new instruments.

The conclusion of this section is that these analyses "raised no new issues of safety and efficacy for the design modifications described herein." This indicates that the intent was to show that the new components did not negatively impact the established safety and efficacy of the existing systems, rather than to present new acceptance criteria or a study demonstrating achievement of those criteria.

Therefore, I cannot provide the requested information from the given text as it is not present. The document focuses on regulatory approval through substantial equivalence, not on quantifiable performance acceptance criteria and a study demonstrating their achievement.

Acceptance Criteria and Device Performance for VEGA Knee System (K140452)

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

This submission (K140452) is for a line extension, specifically the addition of optional compatible Aesculap Columbus CRA/PSA tibial plateau and augments to the existing VEGA Knee System.

• Sample Size for Test Set: Not applicable in the traditional sense of a clinical or in-vitro study with a specific number of units. The assessment was a geometrical worse-case comparison, which would involve analyzing the designs and dimensions of the components rather than testing a "sample size" of physical devices.
• Data Provenance: The data is based on the design specifications and geometrical properties of the existing VEGA Knee System (cleared under K101281 and K121879) and the Columbus CRA/PSA components (previously cleared in 510(K) K053390, K071220 and K120955). This is considered retrospective in the sense that it relies on previously designed and cleared components rather than newly generated test data from a prospective study. The country of origin is not explicitly stated for the designs, but the company is US-based.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified. Given the nature of the "geometrical worse-case comparison," these would likely be engineering experts with expertise in orthopedic implant design, tolerancing, and biomechanics.

4. Adjudication Method for the Test Set

• Adjudication Method: Not applicable. The "study" was a geometrical comparison, not a clinical trial requiring adjudication of patient outcomes or expert consensus on clinical findings.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

• MRMC Study: No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging devices where human readers interpret results, which is not applicable to an orthopedic implant line extension.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

• Standalone Performance Study: No, a standalone algorithm performance study was not done. This type of study is relevant for AI/ML algorithms, which is not applicable to this physical implant device.

7. The Type of Ground Truth Used

• Type of Ground Truth: The ground truth for this submission is based on engineering design principles, dimensional compatibility, and risk analysis methodologies. The "truth" is whether the combined components fit together without creating new risks or compromising the function of the knee system. This is an engineering/design-based ground truth.

8. The Sample Size for the Training Set

• Sample Size for Training Set: Not applicable. This submission does not involve an AI/ML algorithm that requires a training set. The "fundamental scientific technology and materials" for the VEGA system are established.

9. How the Ground Truth for the Training Set Was Established

• Ground Truth for Training Set Establishment: Not applicable, as there is no training set for this device. The underlying design principles and performance of the predicate devices (VEGA and Columbus components) were established through their respective 510(k) clearances, which would have involved various mechanical testing, biocompatibility, and design verification activities.

The VEGA Knee System is indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture.

Posterior Stabilized (PS) components are also for absent or non-functioning posterior cruciate ligament and severe anteroposterior instability of the knee joint.

The VEGA Knee System is designed for use with bone cement.

The VEGA Knee System is a semi-constrained cemented prosthesis with a Posterior Stabilization (PS) design. The femoral component, tibial plateau and extension stem are manufactured from Cobalt Chromium Molybdenum alloy (CoCrMo) with a Zirconium nitride (ZrN) coating. The tibial "gliding surfaces" (inserts) and patella are manufactured from Ultra High Molecular Weight Polyethylene (UHMWPE) and the tibial plug is made of PEEK. The system is made up of numerous components available in various sizes. All components are sterile and for single use only.

The provided document is a 510(k) summary for the VEGA Knee System, specifically addressing a modification to the wrench size for 10mm extension stems. This document is a premarket notification for a medical device that aims to demonstrate substantial equivalence to a legally marketed predicate device, rather than proving a device meets specific clinical acceptance criteria through a study with human subjects.

Therefore, many of the requested data points (such as sample size for test sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, and ground truth for training data) are not applicable to this type of submission for this particular device modification. The submission focuses on mechanical testing to ensure the modification does not negatively impact the device's performance compared to the predicate.

Here's the information that can be extracted from the provided text, alongside an explanation of why other points are not applicable:

1. Table of Acceptance Criteria and Reported Device Performance

• Explanation: For this type of modification (wrench size for extension stems), the "acceptance criteria" are implied to be that the modified component, when subjected to mechanical testing, performs comparably to the previously cleared design. The document doesn't specify numerical thresholds for success, but rather a qualitative comparison.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not specified. The document states "Mechanical testing... was performed," but does not provide the number of samples or specimens tested.
• Data Provenance: The testing was performed internally by the manufacturer (Aesculap Implant Systems, LLC). The nature of the testing is "mechanical testing," implying laboratory-based testing rather than clinical data from a country of origin.
• Retrospective/Prospective: Not applicable. Mechanical testing is a laboratory-based evaluation of physical properties, not a study involving patient data.

3. Number of Experts Used to Establish Ground Truth and Qualifications

• Not applicable. This was mechanical testing of a physical component (extension stem), not an evaluation of a diagnosis or outcome that would require expert human judgment or "ground truth."

4. Adjudication Method

• Not applicable for the same reasons as #3.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

• No. This type of study investigates human reader performance (e.g., radiologists, pathologists) often in the context of diagnostic AI. The submission is for a knee implant modification and involves mechanical testing.

6. If a Standalone (Algorithm Only) Performance Study was Done

• Not applicable. This is a medical device (knee implant), not an algorithm or AI system.

7. The Type of Ground Truth Used

• The "ground truth" for mechanical testing is typically established by engineering specifications, material properties, and comparison to the performance of the predicate device under similar testing conditions. It's not "expert consensus," "pathology," or "outcomes data" in the traditional sense for diagnostic or prognostic studies. The implied ground truth is the established performance of the original VEGA Knee System (K101281) through its own mechanical testing.

8. The Sample Size for the Training Set

• Not applicable. This device is not an AI/ML algorithm that requires a training set.

9. How the Ground Truth for the Training Set was Established

• Not applicable for the same reasons as #8.

Study that Proves the Device Meets the Acceptance Criteria:

The document states: "Mechanical testing of the Aesculap Implant Systems VEGA 10mm extension stems was performed as a result of the risk assessment. The results were found to be similar to the legally marketed VEGA Knee System."

This "mechanical testing" is the study referenced. No further details are provided in this summary regarding the specific tests conducted (e.g., fatigue testing, static strength testing), the number of samples, or the quantitative results. The conclusion provided is that the performance was "similar" to the predicate device, indicating it met the implicit acceptance criterion of not degrading performance due to the modification.
