步态分析技术是利用生物力学手段检测与分析，研究步行规律的检查方法，揭示步态变化的关键环节及影响因素。步态图是步态分析结果的重要呈现形式。近年来，步态分析技术/步态图的应用逐渐普及，尤其在膝关节运动功能及常见疾病诊治、评价及辅助康复等方面开展了较多工作。然而，步态分析技术/步态图在膝关节功能评估过程中的使用尚无规范性文件指引。因此，本共识以现有文献证据为基础，对步态图在膝关节及其相关疾病领域的应用进行系统性回顾，通过多轮德尔菲投票形成了7条共识性推荐意见，涉及步态图的适应范围、禁忌证、围手术期及康复管理、普通人群筛查、特殊类型步态分析及步态图相关参数领域。该共识的发布将对步态图在膝关节运动功能评估及膝关节疾病、运动医疗康复领域的开展，提供有益指导和规范性指引。

Gait analysis technology has developed an examination method using biomechanical measurements for detection and analysis, to investigate walking patterns and reveal the key steps and factors influencing gait changes. Gaitogram is an important presentation of gait analysis results. In recent years, the gait analysis techniques/gaitogram has been gradually applied and popularized, especially in the diagnosis, treatment, evaluation and assistance for rehabilitation of knee joint motion and other common diseases. However, no normative document has yet outlined guidance for the use of gait analysis techniques/gaitogram in evaluating knee joint function. Based upon existing literature and evidence, the application of gaitogram in the areas of knee joint and related diseases was therefore systematically reviewed in this consensus. Seven consensus recommendations, covering indications, contraindications, perioperative management, rehabilitation, general population screening for gaitogram, analysis for special types of gait, and domain of related parameters, were made through multiple rounds of Delphi voting. The release of this consensus serves to provide practical and normative guidance to the use of gaitogram in evaluation of knee joint motion, knee joint diseases and sports rehabilitation.
