The implants of Xpert Knee range are indicated for the fixation of fractures, non-unions and malunions of the proximal tibia in adults.
The Xpert Knee range consists of plates and screws designed for the fixation of fractures, nonunions and malunions of the proximal tibia in adults. The plates and screws of the Xpert Knee range will be provided sterile by gamma sterilization or non-sterile for sterilization by health care professionals prior to use. The instruments of the Xpert Knee range will be provided non sterile for sterilization by health care professionals prior to use. Materials: CP Titanium grade 4 (conform to ASTM F67 and ISO 5832-2) for the plates, and Titanium alloy Ti-6Al-4V ELI (conform to ASTM F136 and ISO 5832-3) for the screws. Function: The implants of Xpert Knee range are indicated for the fixation of fractures, non-unions and malunions of the proximal tibia in adults.
I apologize, but the provided FDA 510(k) clearance letter for the "Xpert Knee" device does not contain any information about acceptance criteria or a study proving the device meets those criteria, especially not in the context of an AI/algorithm-based medical device.
The document primarily focuses on:
- Identity of the device: Xpert Knee, a metallic bone fixation appliance (plates and screws).
- Intended Use: Fixation of fractures, non-unions, and malunions of the proximal tibia in adults.
- Substantial Equivalence: Comparing the Xpert Knee to legally marketed predicate devices (other bone plates and screws) based on material, design, and indications for use.
- Non-clinical testing: Mechanical tests (static and dynamic tests on plates, pullout and torsional tests on screws) to demonstrate performance against the predicate devices.
- Lack of clinical studies: Explicitly states "No clinical studies were performed."
The categories you've asked about (acceptance criteria for algorithms, sample size for test sets, expert ground truth, MRMC studies, standalone performance, training sets, etc.) are all highly relevant to the evaluation of AI or software-as-a-medical-device (SaMD). The Xpert Knee, as described in this 510(k), is a physical medical device (implants), not an AI software. Therefore, the information you're looking for about AI performance is not present in this document.
To answer your request, I would need a 510(k) (or similar regulatory document) for an AI/algorithm-based device.
§ 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)
