The knees have it -- and the shoulders, elbows, hips, wrists, and ankles too. DePuy Orthopaedics, a subsidiary of DePuy (itself part of Johnson & Johnson, or J&J), is one of the largest designers, makers, and distributors of orthopedic devices and supplies. In addition to replacement joints, its 200-plus products includes the Ci system, which includes computer hardware and software needed to assist surgeons in such procedures as full knee replacement surgery and ligament balancing. DePuy Orthopaedics was founded in 1895 by Revra DePuy. One of J&J's fastest-growing businesses, the company continues to innovate and expand through research and development efforts, as well as through acquisitions.
