In 2001, Dr. Hodge designed and patented the 3D(Data Driven Design) Knee, a revolutionary concept in knee replacement with extensive research behind it. It is now manufactured by DonJoy Medical Corporation.

The 3D Knee accommodates the lifestyle of a highly active individual by providing increased strength and durability. The 3D Knee has a 150-degree range of motion, which is similar to normal knees and superior to the 115 degrees of motion allowed by other artificial knees.

 Since 2001 the 3D Knee has become one of the fastest growing designs in the world.
