Charnley

Charnley is a surname of English origin and, less commonly, a place-name in England. It has appeared in historical records since the Middle Ages and has been adopted by families in various regions. As a place-name, it presumably derives from an English toponym, though the exact origin is not definitively recorded. The best-known bearer is Sir John Charnley (1911–1982), a British orthopedic surgeon who pioneered the modern total hip arthroplasty, establishing hip replacement as a standard procedure in the mid-20th century and influencing contemporary orthopedic practice. The surname remains in use today in the United Kingdom and elsewhere.
