研究设计：横断面研究。目的：确定前交叉韧带 (ACL) 断裂后具有和不具有动态膝关节稳定性的患者的分布是否因年龄、性别以及接触性与非接触性损伤机制而不同。背景：ACL 断裂后恢复到受伤前活动的情况存在差异。目前尚不清楚是否有特定的患者群体在 ACL 断裂后或多或少有可能经历良好的动态膝关节稳定性。 方法和措施：研究样本由 345 名连续的、高度活跃的完全、孤立的 ACL 功能不全的患者组成。根据筛选检查的结果，患者被分为具有良好（潜在铜）或差（非铜）动态膝关节稳定性。计算描述性和卡方统计数据来描述患者特征，并根据年龄、性别和损伤机制确定潜在的应对者和非应对者的比例。 结果：不应对者比例最大的群体是女性 (P = 0.002)、中年人 (35-44 岁) (P
STUDY DESIGN: Cross-sectional study.OBJECTIVES: To determine whether the distribution of those with and without dynamic knee stability after anterior cruciate ligament (ACL) rupture differs by age, gender, and contact versus noncontact injury mechanisms.BACKGROUND: There is a differential return to preinjury activities after ACL rupture. It is unknown if there are specific patient groups that are more or less likely to experience good dynamic knee stability after ACL rupture.METHODS AND MEASURES: The study sample consisted of 345 consecutive, highly active patients with complete, isolated ACL insufficiency. Based on the results of a screening examination, patients were categorized as having either good (potential coper) or poor (noncoper) dynamic knee stability. Descriptive and chi-square statistics were calculated to describe patient characteristics and identify the proportion of potential copers and noncopers based on age, gender, and injury mechanism.RESULTS: The groups with the greatest proportion of noncopers were women (P =.002), mid-aged adults (35-44 years) (P
