The knee is considered the most common injured joint between young sport participants. However, there is lack of proper prevalence estimation in our population. The purpose of this study was to identify the prevalence of knee injuries among male college students and to observe the demographic data associated with it. Our secondary objective was to evaluate the awareness and knowledge about these injuries. This is a cross-sectional study. A survey was distributed to collect the data among male college students, King Saud University, Riyadh, Saudi Arabia. Out of 688 students who participated and completed the questionnaire, a total of 482 were considered valid and met the inclusion criteria. Data were analyzed using Statistical Package for Social Sciences (SPSS). The overall prevalence of knee injury was 23.2% (n = 112). Most of them injured during sport activities especially soccer and 68.7% involved in a non-contact mechanism of injury. Among those who went to a hospital mostly were diagnosed as contusion (31.4%) then as meniscus tear, ACL, and collateral ligament injury, respectively. Majority was treated conservatively and only 10.7% needed surgery surprisingly. There was no statistically significant difference between those who are injured and whether they were warmed up and stretched or not (P = 0.619). Low level of knowledge about knee injuries was noticed among the participants 57.7%. Our study has highlighted the high prevalence of knee injuries and the need to raise the level of awareness and knowledge about these injuries in our population. Soccer was the most common sport associated with knee injuries; most of these injuries were treated conservatively.

沙特阿拉伯利雅得男大学生膝盖受伤的患病率

膝盖被认为是年轻运动参与者之间最常见的受伤关节。但是，我们的人口缺乏适当的流行率估计。这项研究的目的是确定男性大学生中膝盖受伤的患病率，并观察与之相关的人口统计学数据。我们的次要目标是评估有关这些伤害的认识和知识。这是一项横断面研究。沙特阿拉伯利雅得沙特国王沙特大学（King Saud University）进行了一项调查以收集男大学生的数据。在参加并完成问卷的688名学生中，共有482名被认为有效且符合纳入标准。使用社会科学统计软件包（SPSS）分析数据。膝关节损伤的总患病率为23.2％（n = 112）。他们中的大多数人在体育活动中受伤，尤其是在足球比赛中，有68.7％的人参与了非接触式受伤机制。在那些去医院的人中，大多数被诊断为挫伤（31.4％），然后分别被诊断为半月板撕裂，ACL和副韧带损伤。多数患者接受保守治疗，仅10.7％的患者需要手术治疗。受伤者与是否被热身或伸展起来之间没有统计学上的显着差异（P = 0.619）。参与者中，关于膝部受伤的知识水平较低，为57.7％。我们的研究强调了膝关节损伤的高发率，并且需要提高人们对这些损伤的认识和知识水平。足球是膝伤最常见的运动。
