The Scandius TriTis Absorbable Tibial Reconstruction System is intended for use in the fixation of ligament and tendon grafts during anterior cruciate ligament (ACL) reconstructions of the knee.

Device Description

The TriTis Absorbable Tibial Reconstruction System consists of a three piece implant designed to fixation soft tissue for tibial ACL reconstruction. The graft cleat secures the soft tissue graft in the tunnel. The washer and fixation screw secures the ends of the graft and cleat to the bone. The System includes instrumentation to prepare the bone tunnel and place the device as well as a sterilization trav.

AI/ML Overview

Here's an analysis of the provided text regarding the Scandius TriTis Absorbable Tibial Reconstruction System, focusing on acceptance criteria and supporting studies:

Acceptance Criteria and Device Performance (Based Solely on Provided Text):

Acceptance Criteria Category	Specific Criteria (Inferred from text)	Reported Device Performance
Mechanical Strength	Ultimate failure strength	"demonstrates that any minor technological differences do not raise any new questions of safety and effectiveness." (Implies meeting or exceeding predicate's performance)
Biocompatibility/Material	Absorbable material properties	Device described as "Absorbable," implying the material meets requirements for an absorbable implant.
Intended Use	Fixation of ligament/tendon grafts for ACL reconstruction	Device has the "same intended and indication for use" as the predicate.
Technical Characteristics	Similar to predicate device	"have similar technical characteristics and principles of operation."

Study Information:

Sample size used for the test set and the data provenance:
- Test Set Sample Size: Not explicitly stated.
- Data Provenance: Not explicitly stated (e.g., country of origin, retrospective/prospective). The document mentions "Bench testing," which implies laboratory conditions.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the given text. "Bench testing" suggests a non-human-reader-based evaluation.
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This is not applicable as the described study is "Bench testing" and does not involve human interpretation or a "test set" in the context of diagnostic performance.
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:
- No, an MRMC comparative effectiveness study was not done. This document describes a medical device for surgical reconstruction, not an AI-assisted diagnostic tool.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, a "standalone" performance evaluation was done in the form of "Mechanical ultimate failure strength" bench testing. This is an assessment of the device's physical properties without human intervention.
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- The "ground truth" for the bench testing would be engineering specifications and established biomechanical standards for ultimate failure strength for such devices, likely derived from predicate devices or industry benchmarks.
The sample size for the training set:
- Not applicable. This device is a physical implant, not an AI algorithm that requires a training set.
How the ground truth for the training set was established:
- Not applicable. This device is a physical implant, not an AI algorithm.

Dear Mr. Bannon:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the

{3}------------------------------------------------

Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.

Regulation Number and Section

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
