CONSERVERecalls & reported problems across all models

We found 74 models of CONSERVE by Microport Orthopedics Inc. in the FDA's device registry (GUDID). Together they are named in 238 adverse event reports in the FDA's MAUDE database, received between Mar 10, 2016 and Dec 10, 2025 — classified as 233 injuries, 5 malfunctions.

The most frequently reported specific device problem is “Insufficient Device Problem Information” (104 reports).

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.
