under the knife

On operating table

Under the knife means undergoing surgery.

The knife is the surgeon's scalpel: She's going under the knife tomorrow for her hip replacement.

The phrase emphasizes the vulnerability of surgical patients—you're literally being cut open.

It applies to any operation, from routine procedures to major interventions: He's been under the knife three times this year.
