Is Orthopaedic or Orthopedic More Correct?
Neither is universally more correct.
The correct choice depends on the English variety you are following.
If you are writing for readers in the United States, use orthopedic.
If you are writing for readers in the United Kingdom, use orthopaedic.
This is similar to other British and American spelling differences such as colour and color or favour and favor.
Why Does the Confusion Exist?
The confusion comes from differences between British and American spelling conventions.
The word has historical roots in French and Greek. Oxford traces orthopaedics to the French orthopédie and Greek elements meaning roughly “straight” and “rearing of children.” The term originally focused on correcting skeletal problems in children.
Over time, American English commonly developed the shorter orthopedic form, while British English retained orthopaedic.
As a result, both spellings remain established in modern English.
Orthopedics or Orthopaedics?
The same regional difference applies to the name of the medical specialty.
American English: orthopedics
British English: orthopaedics
For example:
- US: He specializes in orthopedics.
- UK: He specializes in orthopaedics.
Cambridge specifically labels orthopedics as US usage and gives orthopaedics as the UK form.

This simple association can help you choose the right form when writing for a specific audience.
Professional Writing Recommendation
