FDA's MAUDE database holds 312 reports that name the brand "Simplex P-Japanese Twin Pack" (implant), received between April 2006 and December 2025; the manufacturer given most often on reports is Stryker Orthopaedics-Mahwah. Spellings of one product vary from report to report.

1 reports arrived in the 12 months to August 2026, down 89% from 9 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 malfunction (71.5%), injury (17.9%) and death (10.6%); across all bone cement reports (product code LOD) death is recorded in 3.6% and malfunction in 22.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device operates differently than expected (23.7%), insufficient device problem information (11.5%) and break (9%). The patient problems coded most often are death, low blood pressure/ hypotension and cardiac arrest. 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."
