The Acculoc Total Knee System is indicated in knee arthroplasty for relief of pain and/or improved knee function in skeletally mature patients with severe knee pain and disability due to rheumatoid arthritis, primary and secondary traumatic arthritis, avascular necrosis of the femoral condyle, posttraumatic loss of joint configuration. Moderate valgus, varus, or flexion deformity in which the ligamentous structures can be returned to adequate function and stability. This device may also be indicated in correction of unsuccessful osteotomy, arthrodesis, or failure of previous arthroplasty procedure. The Acculoc Total Knee System is designed for cemented use only.
The Acculoc Tibial tray is a component of "Acculoc Total Knee System" cleared under K170753 which consist of Femoral component, Tibial tray, Tibial Insert, Patella components and Instrumentation- Acculoc Total Knee Instrumentation System for use with the implants components. The current premarket notification is related to the addition of the Acculoc Tibial tray manufactured from CoCrMo alloy (Cobalt-chromium-molybdenum alloy), this is same size and same design with the predicate device tibial tray (K170753) and only the material is different. The Tibial tray AP and ML size ranges are exact same as the predicate device Tibial tray (K170753).
The provided text is a 510(k) premarket notification for a medical device called the "Acculoc Total Knee System." It specifically focuses on an update to this system, adding a new material (CoCrMo alloy) for the Tibial tray component.
This document does not contain information about acceptance criteria for device performance in the context of an AI/ML algorithm or a clinical study proving its performance against such criteria. Instead, it details:
- Device Name: Acculoc Total Knee System
- Regulatory Information: Product code, regulatory class, regulation number.
- Intended Use/Indications for Use: What the device is designed to do and for whom.
- Predicate Devices: Previously cleared devices that the current one is being compared against for substantial equivalence.
- Device Description: Information about the components and materials.
- Performance Testing: Refers to mechanical and pyrogenicity testing of the physical implant components against relevant ASTM/ISO standards, not clinical performance or performance of a diagnostic algorithm. This is typical for orthopedic implants to demonstrate safety and durability.
Therefore, I cannot answer the questions about acceptance criteria for an AI/ML device, sample sizes for test/training sets, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance because the provided text does not describe such a study or requirements. The "performance testing" mentioned is for the physical knee implant itself, not an AI or diagnostic device.

Dear Jungsun Ha:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
{1}------------------------------------------------
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); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803). please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

§ 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.
