We used MRI to study the lesions in a consecutive group of 64 patients with an acute trauma of the knee and normal plain radiography during the winter season. Bone bruise was present in 35 of the patients, and these were referred to subsequent MRI 4 and 12 months later. After 4 months bone bruise was still present in 69% of the patients and after 12 months in 12%. Soft tissue lesions, for example, lesion in the meniscus, ACL rupture, or MCL lesion was present in 94% of the patients with bone bruise. Interobserver agreement varied from good to excellent. Soft tissue lesions are found in almost all patients with bone bruise, and these generally resolve 4-12 months after the injury. In the patients with no bone bruise the number of ligament injuries was lower.
我们在冬季对连续的64例膝关节急性创伤且X线平片正常的患者进行了MRI检查，以研究其损伤情况。35例患者存在骨挫伤，这些患者在4个月和12个月后接受了后续MRI检查。4个月后，69%的患者骨挫伤仍存在，12个月后仍存在的比例为12%。软组织损伤，如半月板损伤、前交叉韧带断裂或内侧副韧带损伤，在94%的骨挫伤患者中存在。观察者间的一致性从良好到优秀不等。几乎所有骨挫伤患者都存在软组织损伤，这些损伤通常在受伤后4至12个月内消退。在无骨挫伤的患者中，韧带损伤的数量较少。
