222 medical device reports received by FDA name the brand "Synvisc One Synvisc One" (intra-articular hyaluronic acid); the manufacturer given most often on reports is Genzyme Biosurgery Ridgefield; received from October 2013 to April 2018. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (95%) and death (1.8%); across all acid, hyaluronic, intraarticular reports (product code MOZ) death is recorded in 3.7% and malfunction in 8.1%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are insufficient device problem information (18%), patient-device incompatibility (11.3%) and device operates differently than expected (5.9%). The patient problems coded most often are pain, joint swelling and swelling. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
