The KineMatch™ Patello-Femoral Resurfacing Implant is intended to be used in patellofemoral joints with degenerative arthritis of the distal femur and patella, patients with a history of patellar dislocation or patella fracture, or patients with failed previous surgery where patello-femoral joint pain, deformity, or dysfunction persists. The KineMatch™ Patello-Femoral Resurfacing Implant is intended for use with bone cement.
Not Found
This document is a 510(k) premarket notification letter from the FDA to Kinamed Incorporated for their KineMatch™ Patello-Femoral Resurfacing Implant. It states that the device has been found substantially equivalent to legally marketed predicate devices.
This document does not contain information about the acceptance criteria or a study proving the device meets acceptance criteria as requested in the prompt.
The prompt asks for details related to an AI/ML device and its performance, including:
- Acceptance criteria and reported device performance.
- Sample size and data provenance for the test set.
- Number and qualifications of experts for ground truth establishment.
- Adjudication method for the test set.
- Multi-reader multi-case (MRMC) comparative effectiveness study results.
- Standalone algorithm performance.
- Type of ground truth used.
- Sample size and ground truth establishment for the training set.
Since the provided document is a 510(k) clearance for a physical medical implant (a knee joint prosthesis), it does not involve AI/ML performance studies, ground truth establishment, or human reader comparisons. Therefore, I cannot extract the requested information from this text.
§ 888.3540 Knee joint patellofemoral polymer/metal semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemoral polymer/metal semi-constrained cemented prosthesis is a two-part device intended to be implanted to replace part of a knee joint in the treatment of primary patellofemoral arthritis or chondromalacia. 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 a component made of alloys, such as cobalt-chromium-molybdenum or austenitic steel, for resurfacing the intercondylar groove (femoral sulcus) on the anterior aspect of the distal femur, and a patellar component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those devices intended for use with bone cement (§ 888.3027). The patellar component is designed to be implanted only with its femoral component.(b)
