Anterior cruciate ligament injury diagnoses are often missed at initial presentation. Though better diagnosed by physical examinations when done by orthopaedics surgeons, proper history is also important in diagnosing it. This study aimed to find the prevalence of anterior cruciate ligament injury among patients with knee injury visiting the out-patient Department of Orthopaedics of a tertiary care centre.
This descriptive cross-sectional study was conducted on patients visiting the out-patient Department of Orthopaedics of a tertiary care centre within the study period from 31 January 2019 to 1 February 2020, after obtaining clearance from the Institutional Review Committee [Reference number: 321(6-11-E)2/075/076]. The anterior cruciate ligament injury diagnosis was made using a Magnetic Resonance Imaging scan. They were inquired about the specific history features at the time of injury: leg giving way, inability to continue the activity, massive swelling of knee joint within 6 hours, and 'pop' heard or felt. Point estimate and 95% Confidence Interval were calculated.
Among 127 cases of knee injury, anterior cruciate ligament injury was found in 109 (85.83%) (79.76-91.89, 95% Confidence Interval). History of the leg giving way, inability to continue the activity, massive swelling of the knee and 'pop' heard or felt were present in 90 (82.60%), 92 (84.40%), 91 (83.50%), and 86 (78.90%) cases of anterior cruciate ligament injury respectively. At least two history features were present in 104 (95.41%) cases.
The prevalence of anterior cruciate ligament injury was found to be similar to the published studies.

前交叉韧带损伤在初次就诊时经常被漏诊。虽然由矫形外科医生进行体格检查时可以更好地诊断，但正确的病史对诊断也很重要。本研究旨在调查在三级保健中心的矫形外科门诊就诊的膝关节损伤患者中前交叉韧带损伤的患病率。
本研究为描述性横断面研究，于 2019 年 1 月 31 日至 2020 年 2 月 1 日期间在三级保健中心的矫形外科门诊就诊的患者中进行，研究获得了机构审查委员会的批准[参考编号：321(6-11-E)2/075/076]。前交叉韧带损伤的诊断采用磁共振成像扫描。他们被询问受伤时的具体病史特征：腿部发软、无法继续活动、膝关节在 6 小时内出现大量肿胀、听到或感觉到“弹响”。计算点估计值和 95%置信区间。
在 127 例膝关节损伤患者中，发现前交叉韧带损伤 109 例（85.83%）（79.76-91.89，95%置信区间）。腿部发软、无法继续活动、膝关节大量肿胀和听到或感觉到“弹响”的病史分别见于 90 例（82.60%）、92 例（84.40%）、91 例（83.50%）和 86 例（78.90%）前交叉韧带损伤患者。至少有两个病史特征存在于 104 例（95.41%）患者中。
前交叉韧带损伤的患病率与已发表的研究相似。
