The study population was divided into two groups: the unilateral group, including unilateral (five children with unilateral) and bilateral (five children with bilateral DDH). Ten healthy children were recruited for the control group. Spatiotemporal, kinematic, stiff-knee gait (SKG), and kinetic gait characteristics were analyzed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Stance time was significantly shorter in both the unilateral (median [IQR]; 590\u00a0ms, [560.0\u2013612.5] and bilateral (575\u00a0ms, [550\u2013637.5]) groups than in the control group (650, [602.5\u2013677.5]) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), whereas swing time did not differ substantially (<jats:italic>p<\/jats:italic>\u2009=\u20090.065) There was no considerable difference in the mean knee flexion at swing between the unilateral (31.6\u00b0, [30\u201336]) and control (30.11\u00b0, [27.8\u201333.6] groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), but the bilateral group (28.5\u00b0, [24.9\u201332.1]) showed the lower values than the other groups (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001 for bilateral vs unilateral group; <jats:italic>p<\/jats:italic>\u2009=\u20090.008 bilateral vs unilateral group). All the SKG parameters significantly differed among the groups in multi-group comparisons (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001 for each parameter). Three children had borderline SKG, and two had not-stiff limbs in the unilateral group. In the bilateral group, four children had stiff limbs, and one had borderline SKG. Most kinetic gait parameters were not statistically different between groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This study has revealed notable deviations in gait patterns of children with DDH treated by MOR at long-term follow-up compared to healthy children\u2019s gait.
