Relationship between bone bruise volume and the presence of meniscal tears in acute anterior cruciate ligament rupture

摘要

Purpose To determine whether there is a relationship between the size of the bone bruise volume after an acute anterior cruciate ligament (ACL) rupture and the presence of meniscal tears in the medial and lateral compartment. Methods Following Institutional Review Board approval, 50 patients with an acute ACL rapture and MRI imaging within 30 days of injury were identified. Two musculo-skeletal radiologists evaluated the lateral and medial menisci and graded them as one of the following: no meniscal tear, tear of one meniscus (medial or lateral) or tear of both menisci (medial and lateral). Sagittal T2 fat-suppressed images were used to calculate bone bruise volume. The relationship between bone braise volume and the presence of a meniscus tear was calculated.
