Multiligament knee injuries remain a challenge for the treating surgeon and little is known about the injury patterns and factors determining clinical and gait outcomes after multiligament knee reconstruction (MLKR). This article aims to identify specificities of this complex injury, in terms of demographics, mechanisms of injury, injury pattern, and associated lesions. The time frame between injury and surgery and distribution of repair versus reconstruction procedures have been analyzed. This study reports functional and clinical outcomes, providing an overview of expected results. Using motion capture gait analysis, knee kinematics and gait characteristics of MLKR patients have been assessed.
