About
Masayoshi Yagi is a pioneering figure in orthopaedic biomechanics, best known for his transformative work on anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction. His research centers on restoring native knee kinematics through anatomically precise, multi-bundle surgical techniques. Yagi’s landmark 2002 study, cited over 980 times, demonstrated that anatomic two-bundle ACL reconstruction restores knee stability more closely to normal than traditional single-bundle methods, challenging the prevailing focus on the anteromedial bundle alone. He further quantified in situ forces within the ACL under rotatory loads (671 citations), revealing the critical role of the posterolateral bundle in resisting rotational instability. His work on double-bundle PCL reconstruction (359 citations) extended these principles to the posterior cruciate ligament, while his comparative analysis of hamstring versus patellar tendon grafts (511 citations) provided essential evidence for graft selection. Yagi also advanced the use of robotic technology for joint research, enabling precise, repeatable biomechanical testing. His contributions have fundamentally shaped modern ACL reconstruction, directly influencing surgical practice and improving patient outcomes worldwide.
