12 reports arrived in the 12 months to August 2026, up 20% from 10 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 (97%), malfunction (1.8%) and death (1.2%); across all prosthesis, shoulder, semi-constrained, metal/polymer cemented reports (product code KWS) death is recorded in 0.1% and malfunction in 10.9%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device dislodged or dislocated (23.8%), insufficient device problem information (10.7%) and detachment of device or device component (7.7%). The patient problems coded most often are pain, joint dislocation and failure of implant. 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."
