Quadriceps dysfunction leads to aberrant gait biomechanics that are hypothesized to contribute to post-traumatic knee osteoarthritis (PTOA) following anterior cruciate ligament reconstruction (ACLR). Graded walking (uphill and downhill) may exacerbate abnormalities that otherwise go unnoticed. The purpose of this study was to compare quadriceps electromyography (EMG) amplitudes between level, uphill, and downhill walking conditions in individuals at least one year post-ACLR. Quadriceps EMG was sampled in 24 ACLR and 27 healthy controls during treadmill walking. Quadriceps EMG centered on heel strike differed up to 25% between groups, though not significant. Significant correlations were observed between involved limb: peak torque and uphill EMG change scores, and rate of torque development 100ms after activation and uphill EMG change scores centered on heel strike and at 50% of stance. Quadriceps dysfunction remains present in ACLR individuals compared to healthy controls when walking uphill. Current rehabilitation may be insufficient to address this specific condition.
