David Halley (birthdate) is an American orthopedic surgeon. He has performed more than 4,000 hip and 4,000 knee replacements during his active career as a surgeon in Columbus, Ohio. He studied with Sir John Charnley who pioneered the hip replacement operation, which is now one of the most common operations in the world.

He also pioneered, with business partner, mechanical engineer, Paul Ewing, a revolutionary method of recovery from knee surgery called the X10 Knee Recovery System™ which was introduced in 2011.}}

The X10™
In 2007 Dave Halley conceived a new method of recovery from knee replacement surgery with longtime friend and engineer Paul Ewing.

The objective was simple: improve the results of knee surgery through new rehabilitation technology. The result of years of research and development was the first model of the X10 Knee Rehabilitation Machine in 2011. Since then many thousands of knee patients have recovered using the X10™.
