Patients Walking Faster After Anterior Cruciate Ligament Reconstruction Have More Gait Asymmetry.

ABSTRACT:

Background

Gait asymmetries after anterior cruciate ligament reconstruction (ACLR) may lead to radiographic knee osteoarthritis. Slower walking speeds have been associated with biomarkers suggesting cartilage breakdown. The relationship between walking speed and gait symmetry after ACLR is unknown.

Hypothesis/purpose

To determine the relationship between self-selected walking speeds and gait symmetry in athletes after primary, unilateral ACLR.

Study design

Secondary analysis of a clinical trial.

Methods

Athletes 24±8 weeks after primary ACLR walked at self-selected speeds as kinematics, kinetics, and electromyography data were collected. An EMG-driven musculoskeletal model was used to calculate peak medial compartment contact force (pMCCF). Variables of interes
