Gait pattern comparison between a series of patients having undergone medial patellofemoral ligament (MPFL) reconstruction and a sample of control subjects. Thirty patients at 6\u00a0months postoperatively after MPFL reconstruction and thirty control subjects were enrolled in the study for a clinical and biomechanical assessment including gait analysis at three selected walking rates using the GAITRite<jats:sup>\u00ae<\/jats:sup> system. The mean raw IKDC score was 73 (\u00b119), and the mean Kujala knee function was 84 (\u00b117.5). The study of gait did not demonstrate any significant difference between the two groups at a normal and fast walking rate. At a 10\u00a0km\/h running speed, the single\u2010support phase was significantly shortened by a mean 2.33 % (<jats:italic>p<\/jats:italic> &lt; 0.05), the swing phase by a mean 2.64 % (<jats:italic>p<\/jats:italic> &lt; 0.05) and the double\u2010support phase by a mean 3.49 % (<jats:italic>p<\/jats:italic> &lt; 0.05) on the operated side. MPFL reconstruction reported good midterm functional and clinical results in the management of OPI. At 6\u00a0months postoperatively, the patient gait pattern was similar to that observed in healthy subjects at a normal and fast walking speed. However, our study revealed persistent gait abnormalities at a 10\u00a0km\/h running speed. These gait alterations seemed to be related to the ligament reconstruction in itself due to the higher strain applied on the reconstructed MPFL during running cycle (10\u00a0km\/h).<\/jats:p><jats:p><jats:italic>Level of evidence<\/jats:italic>
