Prophecy Incompass

PHOENIX – October 29, 2026 -- Dr. Jason Patterson of OrthoArizona is the first surgeon worldwide to perform total ankle replacement with Stryker's Prophecy Incompass patient-specific instrumentation, completing three procedures in July 2026.

Prophecy builds a 3D-printed surgical guide from the patient's CT scan

The system uses each patient's own CT scan to produce a custom 3D-printed guide before surgery begins. Paired with Stryker's Incompass total ankle system, it lets surgeons switch between stemmed and pegged implants mid-procedure if the exposed joint anatomy requires it.

Patterson has used CT-guided, patient-specific instrumentation for ankle replacement since 2015. He said the latest generation makes implant placement more consistent and surgery more efficient. In his words, the technology lets him plan around a specific patient's anatomy "instead of relying on a generic template."
