Study cites gait differences between patients with non-traumatic and post-traumatic OA

August 26, 2016

Results from this study indicated patients with non-traumatic knee osteoarthritis were different from patients with post-traumatic knee osteoarthritis in regard to knee adduction angles and kinematics during ambulation.

Researchers classified patients with medial knee osteoarthritis (OA) as either non-traumatic (n=122) or post-traumatic (n=93) based on arthroscopic confirmation for evidence of a previous ACL tear. Researchers also conducted a post hoc analysis with patients who had an ACL tear, but no knee OA. Investigators used radiographs to determine Kellgren/Lawrence severity scores and the mechanical axis angle (MAA). Gait analysis was used to calculate the knee flexion, adduction angles and external moments. Waveform characteristics were determined with principal component (PC) analysis, and peak values were identified. The OA groups were examined on whether they predicted peak values and PC scores after investigators controlled for age, gait speed and severity with linear regression models. Investigators then repeated the models with and without controlling for the MAA.
