Kyocera Honored by Japan’s METI for Artificial Hip Joint Technology
The honor recognizes Kyocera’s Aquala surface-processing technology, which was developed in collaboration with The University of Tokyo and has reportedly been demonstrated to extend the life expectancy of artificial hip joints.
Kyocera Corp.’s Aquala® technology received Japan’s Prize of the Minister of Economy, Trade and Industry (METI) during the 2018 National Invention Awards held recently in Tokyo by the Japan Institute of Invention and Innovation (JIII). The honor recognizes Kyocera’s Aquala surface-processing technology, which was developed in collaboration with The University of Tokyo and has reportedly been demonstrated to extend the life expectancy of artificial hip joints. The JIII award program was created in 1919 to recognize original inventions showing excellent future promise.
Artificial hip joints have become a common treatment for hip-joint diseases such as osteoarthritis and certain hip fractures. The artificial joint replaces a portion of the patient’s femur known as the femoral head and its mating surface on the patient’s pelvis, known as the acetabulum. Kyocera developed its Aquala technology to create a low-friction bearing surface on the acetabular side of the joint, which couples with diamond-polished ceramic on the femoral side. According to Kyocera, Aquala technology represents the first Japan-market use of the biocompatible material PMPC to create a nanometer-scale hydrophilic polymer layer with functions similar to human articular cartilage in the implant’s acetabular liner.
Aquala technology is designed to reduce the incidence of wear particles produced at the bearing surface of the artificial joint—which can otherwise lead to peripheral inflammation, loosening of the joint and eventual joint failure. Surgeons have implanted approximately 45,000 total hip replacements using Kyocera’s Aquala technology since it was approved by Japan’s Ministry of Health, Labor and Welfare in 2011.
