The suture anchors are processed from human cortical bone and provided sterile and are intended for single use. The bone soft tissue anchors with attached suture are inserted into a predrilled bone hole site with a single use disposable or a reusable introduction device. The suture ends are pulled to engage cancellous bone and to toggle and lock the anchor in bony tissue. A curved needle attached to the suture end(s) is used to secure soft tissue to bone.

The provided text describes a 510(k) premarket notification for a medical device, the Multitak SSTM Bone Anchor. This type of submission is for demonstrating substantial equivalence to a predicate device, not for proving novel safety and effectiveness through clinical trials with defined acceptance criteria and statistical performance. The information requested (acceptance criteria, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, training sets) is typically associated with AI/ML device submissions or devices requiring clinical performance data for approval, which is not the case here.

However, based on the provided text, we can infer the "acceptance criteria" and "study" in the context of a 510(k) submission as demonstrating substantial equivalence to a predicate device through comparative performance testing on mechanical properties.

Here's an interpretation based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The new Multitak SSTM Bone Anchor (cortical bone) demonstrated equivalent pullout strengths and failure modes to the predicate Multitak SSTM Titanium Anchor (K973015). |

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

• Sample Size: The document does not specify the exact sample size used for the performance testing comparing the new cortical bone anchor to the titanium predicate. It simply states "Performance testing."
• Data Provenance: The data is generated from in vitro performance testing (mechanical testing) of the physical devices, not from human or animal subjects. Details on the location of the testing are not provided. The data is prospective for this specific comparison study.

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

• This concept is not applicable here. Ground truth in this context would be objective physical measurements of mechanical properties (pullout strength, failure modes). These are determined by mechanical testing equipment and protocols, not by expert consensus.

4. Adjudication Method for the Test Set

• Not applicable. Mechanical testing results are quantitative and do not typically require adjudication.

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

• No, an MRMC study was not done. This type of study is relevant for diagnostic imaging devices or devices where human interpretation of medical data is involved. The Multitak SSTM Bone Anchor is a physical surgical implant.

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

• Not applicable. This device is not an algorithm or AI system.

7. The Type of Ground Truth Used

• Objective Mechanical Measurements: The "ground truth" was established through direct
  measurement of physical properties, specifically pullout strength and failure modes, using standardized mechanical testing methods relevant to surgical anchors.

8. The Sample Size for the Training Set

• Not applicable. This device doesn't involve an AI/ML algorithm requiring a training set.

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

• Not applicable. There is no training set for this device.

The provided document describes a 510(k) premarket notification for a medical device called the "Multitak Suture System." This type of submission focuses on demonstrating substantial equivalence to a predicate device already on the market, rather than conducting new clinical studies to establish acceptance criteria and performance against those criteria.

Therefore, much of the requested information, specifically regarding detailed acceptance criteria, study methodologies (test set, ground truth, expert involvement, MRMC studies, standalone performance, training set details), and specific performance metrics in numerical terms, is not available in the provided text.

The document primarily focuses on:

• Identifying the device and its intended use.
• Listing predicate devices.
• Stating that performance data was collected (pullout testing).
• Concluding that the device is substantially equivalent to predicate devices based on this testing.

Here's an attempt to answer the questions based only on the provided text, highlighting what is missing:

1. Table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance

• Sample Size: Not specified.
• Data Provenance: Not specified (e.g., country of origin, retrospective/prospective). The document only mentions "pullout testing," which implies laboratory or bench testing rather than human clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

• Number of Experts: Not applicable, as this was likely bench testing, not an expert-driven ground truth assessment.
• Qualifications of Experts: Not applicable.

4. Adjudication method for the test set

• Adjudication Method: Not applicable, as this was likely bench testing.

5. 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

• Standalone Performance: No, this device is a physical surgical implant, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• Type of Ground Truth: For the "pullout testing," the ground truth would inherently be against a quantitative measurement of the mechanical property (pullout strength) of the device itself and its predicate. It's not a clinical "ground truth" derived from patient outcomes or pathology.

8. The sample size for the training set

• Sample Size: Not applicable. This device is a physical medical device, not an AI model, and therefore does not have a "training set."

9. How the ground truth for the training set was established

• Ground Truth Establishment: Not applicable, as there is no training set for this type of device.

Summary of the "Study" (Per the Document):

The document states that the Multitak Suture System underwent pullout testing. The "proof" that it meets acceptance criteria (which are implied to be "equal to or better than the predicate device's pullout strength") is the conclusion that the device "demonstrated pullout strength equal to or better than the predicate device(s)." This is a comparative biomechanical study, not a clinical trial with human subjects. The full details of this testing (e.g., specific test methods, number of samples, statistical analysis) are not provided in this summary.

Summary of What's Missing and Why:

The provided document is a 510(k) summary for a medical device (a suture anchor system). These summaries typically focus on demonstrating substantial equivalence to predicate devices, rather than providing the detailed technical and statistical results of comprehensive clinical or AI performance studies.

Specifically, for the "Performance Data" section:

• It states that the device was "compared in pullout testing to the predicate device" and "found to demonstrate pullout strengths superior to those of a suture only reattachment technique." However, it does not provide:
  • Specific quantitative pullout strength values for the device or the comparator.
  • Statistical significance testing details (e.g., p-values, confidence intervals).
  • The type of material used for testing (e.g., cadaver bone, synthetic bone).
  • The number of samples tested (sample size).
• It states "Insertion testing was performed to verify insertion and locking at all indicated sites." Again, no specific data, methodology, or acceptance criteria are given.

Therefore, while the document confirms performance testing was done, it lacks the detailed information required to fully answer many of your questions, particularly regarding specific numerical acceptance criteria, sample sizes, and detailed performance metrics.

Here's an overview of what is available in the given text, rephrased to fit the context of device performance, even though it's not AI/ML performance:

1. A table of acceptance criteria and the reported device performance

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

• Sample Size: Not specified. The document only mentions "cadaver bone". No specific number of samples or cadavers is provided.
• Data Provenance: The test was performed on "cadaver bone." The country of origin is not specified. It is an experimental, prospective test of the device's mechanical properties.

3. 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 is a mechanical performance test, not a diagnostic or interpretation study. "Ground truth" would be the measured pullout strength.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable. This is a mechanical performance test, not a study requiring adjudication of expert opinions. The ground truth is directly measured physical force.

5. 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. This is a physical device; there are no "human readers" or "AI assistance" involved in its direct mechanical performance testing.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

• Not applicable. This device is not an algorithm. Its performance is entirely "standalone" in the sense that its mechanical properties are inherent to the device itself.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

• The "ground truth" for the performance test was the measured pullout tension (force) in cadaver bone, compared against established values or performance of a predicate device.

8. The sample size for the training set

• Not applicable. There is no "training set" as this is not an AI/ML device.

9. How the ground truth for the training set was established

• Not applicable. There is no "training set."
