This cohort comprised 43 patients with mild-to-moderate bilateral KOA (Kellgren-Lawrence grade 2-3), 43 patients with severe bilateral KOA (Kellgren-Lawrence grade 4), and 27 healthy volunteers (healthy control group). The visual analogue scale (VAS) score for pain, the Hospital for Special Surgery (HSS) score, passive knee range of motion (ROM), and hip-knee-ankle angle (HKA) were used to assess walking pain intensity, joint function, and lower limb alignment in KOA patients, respectively. Motion trajectories of reflective markers and ground reaction force data during walking were captured using a gait analysis system. Musculoskeletal modeling was then employed to calculate biomechanical parameters, including the peak knee adduction moment (KAM), KAM impulse, peak joint contact force (JCF), and peak medial/lateral contact forces (MCF/LCF). Statistical analyses were performed to compare differences in clinical and gait parameters between bilateral limbs. Additionally, one-dimensional statistical parametric mapping was utilized to analyze temporal gait data.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Mild-to-moderate KOA patients showed the significantly higher HSS score (67.7±7.9) than severe KOA patients (51.9±8.9; &lt;i&gt;t&lt;/i&gt;=8.747, &lt;i&gt;P&lt;/i&gt;&lt;0.001). The more painful limb in all KOA patients exhibited significantly greater HKA and higher VAS scores compared to the less painful limb ( &lt;i&gt;P&lt;/i&gt;&lt;0.05). While bilateral knee ROM did not differ significantly in mild-to-moderate KOA patients ( &lt;i&gt;P&lt;/i&gt;&gt;0.05), the severe KOA patients had significantly reduced ROM in the more painful limb versus the less painful limb ( &lt;i&gt;P&lt;/i&gt;&lt;0.05). Healthy controls showed no significant bilateral difference in any biomechanical parameters ( &lt;i&gt;P&lt;/i&gt;&gt;0.05). All KOA patients demonstrated longer stance time on the less painful limb ( &lt;i&gt;P&lt;/i&gt;&lt;0.05). Critically, severe KOA patients exhibited significantly higher peak KAM, KAM impulse, and peak MCF in the more painful limb ( &lt;i&gt;P&lt;/i&gt;&lt;0.05), while mild-to-moderate KOA patients showed the opposite pattern with lower peak KAM and KAM impulse in the more painful limb ( &lt;i&gt;P&lt;/i&gt;&lt;0.05) and a similar trend for peak MCF.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Patients with mild-to-moderate KOA effectively reduce load on the more painful limb through compensatory mechanisms in the less painful limb.
