How accurate is an MRI at diagnosing injured knee ligaments?

Abstract

MRI is highly accurate in diagnosing injury to the anterior cruciate ligament (ACL) (strength of recommendation [SOR]: A, prospective blinded cohort studies) and posterior cruciate ligament (PCL) (SOR: B, limited number of prospective blinded cohort studies). Insufficient data are available to evaluate the effectiveness of magnetic resonance imaging (MRI) for diagnosing injuries to the medial collateral ligament (MCL) and lateral collateral ligament (LCL).
