Learning Objectives:

Elizabeth Frick

Explain the relationships between ground reaction force metrics and knee kinetics in running biomechanics after ACLR and their implications for return to sport decision making

Joe Wittmann

Describe key biomechanical changes in running gait commonly observed following anterior cruciate ligament (ACL) reconstruction.

Identify the clinical utility of 2D video assessment in evaluating running biomechanics post-ACL reconstruction.

Apply a structured framework to assess running mechanics using readily available video tools in a clinical or field-based setting.

Integrate video-based biomechanical findings into clinical decision-making for return-to-run and return-to-sport criteria after ACL reconstruction.
