Introduction

Rupture of the anterior cruciate ligament (ACL) is a common injury and often presents with a typical injury pattern. Historic literature has shown that the accuracy of diagnosis of ACL ruptures is poor at the initial medical consultation despite the history of injury strongly suggesting an ACL injury. The aims of this study were to determine: if the accuracy of diagnosis of ACL ruptures at initial presentation has improved over the last decade; grade of medical staff at initial and subsequent consultations; the mechanism of injury; and the subsequent delay in diagnosis and definitive treatment.
