What the Data Shows About Prosthesis, Knee, Femorotibial, Non-Constrained, Cemented, Metal/Polymer

The FDA MAUDE database aggregates 2,458 adverse-event reports for Prosthesis, Knee, Femorotibial, Non-Constrained, Cemented, Metal/Polymer spanning the period from 1993 through 2026. Of these, 1 is classified as a death report, 1,898 as injury reports, and 536 as malfunction reports under FDA adverse-event categorization rules. Report counts do not by themselves indicate a device is unsafe — widely used devices and longer market histories naturally generate larger raw counts, so proportional and comparative reads are more informative than totals alone.

The adverse-event profile breaks down across 5 distinct event types and 11 reported patient-outcome categories, giving a multi-dimensional view that goes beyond a single headline number. A total of 20 distinct product-problem codes appear in the reports, with Adverse Event Without Identified Device or Use Problem topping the list at 567 reports. Reports are associated with 10 different manufacturers in the MAUDE record, reflecting both OEMs and repackagers of this device category.

Annual reporting volume is tracked across 31 years of MAUDE data, with the peak single-year volume reaching 273 reports — trend shape often reflects changes in device adoption, reporting rules, or FDA enforcement focus rather than underlying device behavior alone. Events are documented across 7 reported care-setting categories (hospital, home, ambulatory surgery center, etc.). All figures reflect the openFDA MAUDE snapshot last refreshed on .
