Partial replacement of the articulating surfaces of the knee when only one side of the joint is affected due to compartmental primary degenerative or post-traumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty. The device is a single use implant intended for implantation with bone cement.
The Repicci II Unicondylar Knee consists of femoral and tibial components. The femoral component is anatomic in design.to provide coverage of the condyle from posterior to anterior. The anatomic shape of the femoral component necessitates separate left and right configurations. A central keel and post on the back of the device assist in cement fixation. The device is manufactured from cobalt alloy. Two styles of tibial components are available with this system, an all polyethylene component and a modular metal backed component. The all polyethylene component is universal in geometry. A waffle pattern on the under surface assists in initial fixation. A modular tibial component consists of a metal tray and a polyethylene bearing which is snap fit into the tray by the surgeon.
I am sorry, but the provided text does not contain information about acceptance criteria or a study that proves the device meets those criteria. The document is a 510(k) premarket notification approval letter for the Repicci II Unicondylar Knee, which primarily addresses the device's substantial equivalence to a predicate device and outlines limitations and regulatory requirements. It does not include details on performance studies, sample sizes, expert qualifications, or ground truth establishment relevant to the specific questions asked.

Dear Ms. Beres:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). This decision is based on this device being equivalent only to similar devices labeled and intended to be fixed within bone with acrylic "bone cement." You may, therefore, market your device subject to the general controls provisions of the Act and the following limitations:
- The thinnest tibial insert available is the nominal 1. "8.0mm" sized insert, which has a minimum polyethylene thickness under the condyles of 6.0mm.
- The thinnest all-poly tibial tray component available is 2. the nominal "8.5mm" sized component, which has a minimum polyethylene thickness under the condyles of 8.5mm.
- This device may not be labeled or promoted for 3 . non-cemented use.
- All labeling for this device, including package label 4 . and labeling included within the package, must prominently state that the device is intended for cemented use only.

Paqe 2 - Ms. Patricia Sandborn Beres
- Any non-cemented fixation of this device is considered 5. investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulation under 21 CFR, Part 812. All users of the device for non-cemented fixation must receive approval from their respective institutional review boards (IRBs) and the Food and Druq Administration (FDA) to conduct the investiqation.
The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Reqister. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659.

§ 888.3530 Knee joint femorotibial metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint femorotibial metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace part of 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 consist of a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
