About

Masanobu Ujihira is a pioneering researcher in the biomechanics of synovial joints, with a focus on the tribological properties that govern joint health and artificial joint design. His work investigates how mechanical loading and joint conformity influence lubrication and friction, critical for understanding osteoarthritis and improving prosthetic implants. In his most-cited study (1998, 16 citations), Ujihira used a robotic system to measure how loading duration affects start-up friction in synovial joints, revealing key insights into the time-dependent behavior of natural lubrication. A related study (1998, 5 citations) explored the relationship between joint conformity and lubricating ability, demonstrating how geometric fit enhances fluid film formation and reduces wear. Though his citation counts are modest, Ujihira’s contributions are foundational for tribology in orthopedics, providing experimental methods and data that inform the design of more durable, low-friction joint replacements. His work remains a reference for researchers studying the interplay between mechanical loading, surface geometry, and synovial fluid performance.
