Intended Use

The Ortho Development Balanced Knee™ Modular Tibial System is indicated for patients suffering from severe knee pain and disability. Specific indications include femoral, tibial and patellar replacement due to degenerative bone disease such as rheumatoid arthritis or osteoarthritis, primary and secondary traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral condyles, pseudo-gout, or complications from a previous prosthesis. This device is intended for cemented use only.

The Balanced Knee™ Tibial Tray Pegged is intended for single use in primary total knee replacement only. Indications include:

  • Loss of joint configuration and joint function;
  • Osteoarthritis of the knee joint;
  • Rheumatoid arthritis of the knee joint;
  • Post-traumatic arthritis of the knee joint;
  • Moderate valgus, varus, or flexion deformities;
  • Revision procedures where other treatments or devices have failed.
Device Description

The Ortho Development Balanced Knee™ Modular Tibial System is a semi-constrained total knee replacement system, consisting of tibial components, stem extensions and tibial augments. The devices are manufactured from Ti-6Al-4V alloy per ASTM standards.

AI/ML Overview

The provided text is a 510(k) summary for the Ortho Development Balanced Knee™ Modular Tibial System. This document outlines the device's description, intended use, and comparison to predicate devices for substantial equivalence. It does not contain information about acceptance criteria, device performance from a study, sample sizes, expert involvement, adjudication methods, or ground truth establishment that would typically be found in a study report for an AI/ML device.

The 510(k) process for this device, a knee replacement system, focuses on demonstrating substantial equivalence to already legally marketed devices, primarily by comparing design, function, materials, and intended use. It does not involve performance studies in the same way an AI/ML diagnostic or predictive device would.

Therefore, I cannot provide the requested table and study details. The document explicitly states:

  • "There are no significant differences between the Ortho Development Balanced Knee™ Modular Tibial System and the systems currently being marketed which would adversely affect the use of the product. It is substantially equivalent to these other devices in design, function, material and intended use." (K031201, page 1)

This statement is the core of a traditional medical device's 510(k) submission and explains why the detailed study information relevant to AI/ML device performance is not present.

Dear Mr. Ahmed:

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 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 (301) 594-4659. 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/dsma/dsmamain.html

§ 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.
