510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.

Orthopedic
The partial semi-constrained cemented polymer/metal/polymer knee patellofemorotibial prosthesis is an orthopedic implant intended to replace the medial condyle and patellofemoral compartment of the distal femur using a single device, used with a unicompartmental tibial base and insert and a resurfacing patella, and fixed with bone cement. It is classified as FDA Class 2 under regulation 888.3560 in the Orthopedic specialty, requiring 510(k) clearance, and carries an implant flag. Product code NPJ is not eligible for third-party review.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
