The biggest orthopaedic market on earth, with a registry that is already the world’s largest by procedure count.
American Joint Replacement Registry (AAOS) (AJRR), since 2012
Hip and knee arthroplasty, with shoulder and elbow collected through the linked AAOS shoulder & elbow registry.
The largest registry in the world by cumulative procedure count. Institutional participation is still growing, so coverage is deep but not yet complete.
Registry mapped to the segment model. Rollout is planned and prioritised by demand — no launch date is published.
Pending. AJRR coverage is partial rather than national, so market-size figures would be presented as registry-captured volume, stated plainly — the same honesty rule the platform applies everywhere.

Segment keys, labels and behaviour are identical to the UK product. "Recorded activity" means your team captures site and surgeon activity with manager validation — the platform states plainly that no registry base applies, exactly as it does in the UK for spine, trauma and sports.
A committed launch customer moves United States from pending to build. The registry mapping above already exists; the build loads AJRR data, the national site and surgeon layer, and the local verification sources. Tell us your segments and territories and we will scope it.
Register interest →Three lines in every country: core platform (agreed per contract), segment add-ons (price on application), and optional tailoring modules.
See packaging →The proving ground. RepHQ runs live on NJR data today — every other country on this page follows the same blueprint.
Europe’s biggest joint replacement market, with a registry built around an implant product database — a natural fit for the RepHQ model.
The country that invented the arthroplasty registry. Coverage is near-total and the data culture is decades deep.
Demand sets the rollout order. A named country with named segments is how the next build gets chosen.
