Tomokazu Yoshioka

About

Tomokazu Yoshioka is a leading researcher in orthopedic rehabilitation robotics, with a focus on restoring knee function after major surgeries. His work centers on the clinical application of wearable exoskeleton technology—specifically the single-joint Hybrid Assistive Limb (HAL)—to improve postoperative recovery. Yoshioka’s major contributions include pioneering robotic-assisted knee-extension training protocols for patients undergoing total knee arthroplasty (TKA), opening wedge high tibial osteotomy, and anterior cruciate ligament (ACL) reconstruction. His 2016 study on HAL-assisted training after TKA, cited 30 times, demonstrated significant improvements in knee range of motion during the critical early postoperative period. A subsequent 2017 case report, with 16 citations, extended these findings to high tibial osteotomy patients. More recently, his 2022 open-label trial on ACL reconstruction, garnering 8 citations, established the feasibility and safety of single-joint HAL for neuromuscular rehabilitation. Collectively, Yoshioka’s work bridges engineering and clinical practice, offering evidence that robotic exoskeletons can mitigate postoperative quadriceps dysfunction and pain, ultimately accelerating functional recovery. His research is instrumental in shaping modern, technology-driven rehabilitation protocols.
