Halley Orthopedics and the X10™

Our Team: Paul Ewing

Paul Ewing is the Chief Executive Officer and co-founder of Halley Orthopedics. Mr. Ewing is an industrial engineer who sold in 2000 the specialty cold-forming business he built from the ground up: NSS Technologies Inc, based in Plymouth, Michigan.

Recognizing that eighty percent of health care money for knee replacements is spent after the patient leaves the hospital, Mr. Ewing set out to create an efficient and superior means of recovery. He created the first working model in 2009. With the third generation of X10™ now in patient homes this “smart rehab solution” has changed the recovery opportunity for knee patients.
