The DcPuy AMK Porous Coated CRX Tibial Tray is intended to be used as the tibial component in cemented total knee arthroplasty.
The DePuy AMK Porous Coated CRX Tibial Tray is a cast cobalt chrome tibial tray available in four standard sizes and five "plus" tibial sizes. The tray has a fixed, tapered, cylindrical central stem and two posterior fins originating at the central stern, and porous coating on the undersurface.
I am sorry, but the provided text describes a medical device (DePuy AMK Porous Coated CRX Tibial Tray) and its regulatory submission for substantial equivalence. It does not contain any information regarding acceptance criteria or a study related to device performance in an AI or diagnostic context.
Therefore, I cannot fulfill your request for the specific information regarding acceptance criteria, device performance, sample sizes, ground truth establishment, or clinical study details as none of that information is present in the provided text.
§ 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.
