About
David L. Bernholt is a leading orthopaedic surgeon-scientist whose research focuses on the biomechanics of knee instability, particularly in the context of anterior cruciate ligament (ACL) injuries and their associated bony lesions. His work centers on understanding how posterolateral tibial plateau bone loss—a common consequence of ACL insufficiency—alters knee kinematics, and on optimizing surgical strategies to restore native joint function. In his landmark 2025 study, Bernholt demonstrated that such bone loss leads to pathological rotational instability during a simulated pivot shift, a finding that directly challenges the sufficiency of isolated ACL reconstruction. Crucially, he showed that this altered kinematics can only be corrected with a combined approach of ACL reconstruction and lateral extra-articular tenodesis, not by ACL reconstruction alone. This work, already garnering early citations, provides a biomechanical rationale for a more aggressive surgical algorithm in patients with posterolateral impaction fractures. Bernholt’s research bridges a critical gap between radiographic findings and clinical decision-making, offering actionable insights for surgeons managing complex knee instability. His contributions are shaping the next generation of evidence-based, patient-specific treatment protocols in sports medicine.
