Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $979,260 of the $1,075,183 with a category attached, or 91.1%. Every reported general payment came from a single manufacturer, Zimmer Biomet. Reporting peaked in 2024 at $192,716 and has fallen 82.4% since, to $33,930 in 2025. Among orthopaedic surgery clinicians in WA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
