Every line below is in FDA’s own words, with its source beside it. FDA’s terms are explained in FDA’s own words.
How serious is it, by FDA’s class?
Class II, the middle of FDA’s three classes.
“Products that might cause a temporary health problem, or pose only a slight threat of a serious nature. Example: a drug that is under-strength but that is not used to treat life-threatening situations.”
openFDA, in plain words, its enforcement report fields.
“Class II is a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.”
FDA’s rule, 21 CFR 7.3(m)(2), eCFR.
What these words mean is quoted from openFDA’s field reference and 21 CFR 7.3.
What’s wrong with it?
Due to firmware issues with the prosthetic knee, there is the potential for unintended warnings and device shutdown which could result in patient falls.

“The term “nationwide” is defined to mean the fifty states or a significant portion. Note that subsequent distribution by the consignees to other parties may not be included.”

What this record can’t tell you
- Whether your own one is affected: compare the codes, dates and numbers above with yours. When unsure, ask the firm or the store.
- Where it went after the firm’s first shipments. FDA’s words cover the firm’s initial distribution, and, in FDA’s words, “subsequent distribution by the consignees to other parties may not be included.”
- How many have been returned, corrected or destroyed: FDA’s report doesn’t say.
- Whether anyone was hurt or fell ill: the report doesn’t say.
- How current it is: openFDA publishes FDA’s Enforcement Report weekly, after FDA does, and a firm can announce a recall weeks before it appears there. openFDA’s own caution: “This data should not be used as a method to collect data to issue alerts to the public, nor should it be used to track the lifecycle of a recall.”
- A product with no recall here isn’t safe by that: FDA’s report lists the recalls FDA classified, and when.
