    Abstract:
    INTRODUCTION: Anterior cruciate ligament (ACL) tears are common knee injuries, especially among sportsmen and sportswomen. The aim of this study is to better understand the epidemiology of surgically managed ACL tears sustained in our institution. METHODS: All patients who underwent arthroscopic ACL reconstruction by the senior author of this article in Singapore from 2008 to 2013 were studied. Patients who were diagnosed clinically and/or radiologically to have a complete tear of the ACL and subsequently underwent arthroscopic ACL reconstruction were included. Patients who suffered from traumatic knee dislocation were excluded. Two hundred and ninety-two patients were available for analysis. All patients were operated on by the senior author. RESULTS: 83.9% of patients were male. 60.5, 23.0, 8.46, and 8.11% were of Chinese, Malay, Indian and other origins, respectively. 69.6 and 28.7% were in white-collared and blue-collared jobs, respectively, while 1.69% were unemployed. Mean age at operation was 29.4 years. Mean body mass index was 25.3 kg/m2. 82.4 and 17.6% of ACL tears were sports (contact-27.5%; non-contact-72.5%) and non-sports injuries (activities of daily living-94.2%, road traffic accidents-5.77%), respectively. The top four sporting activities causing ACL tears were soccer, basketball, racquet games and volleyball. 56.2% of ACL tears presented with concomitant knee injuries (medial meniscus-63.4%; lateral meniscus-31.1%; posterior cruciate ligament-5.49%). 84.5% were primary tears. CONCLUSIONS: In this epidemiological review of ACL injuries, we found that ACL injuries tend to cluster within certain population subgroups. Patterns of mechanisms of injuries have been observed. These findings may lead to better preventive and treatment strategies in the management of ACL tears.
