磁共振成像评估半月板Ramp损伤及其与前交叉韧带损伤严重程度的相关性：一项回顾性观察研究。
简介
该回顾性研究纳入252例运动相关膝关节创伤患者，评估RAMP损伤在ACL损伤中的发生率及其与ACL撕裂严重度的关联。结果显示，ACL损伤占43.3%，RAMP损伤总患病率10.7%，且仅见于ACL损伤患者，II、III级ACL损伤中RAMP损伤占比更高（40.7%和37.0%），但差异未达统计学意义（P=0.291）。提示影像科医生应重视RAMP损伤的报告，…
英文摘要
BACKGROUND: Meniscal ramp lesions are frequently associated with anterior cruciate ligament (ACL) injuries and are often overlooked on magnetic resonance imaging (MRI). Their relationship with the severity of ACL injury remains incompletely understood. OBJECTIVE: The purpose of this study is to determine the association of meniscal rupture of the posterior meniscocapsular attachment (RAMP) lesions in anterior cruciate ligament (ACL) injury and evaluate the different grades of RAMP lesions with the severity of ACL tear. SUBJECTS AND METHODS: This retrospective study included 252 patients who underwent magnetic resonance imaging (MRI) knee examination with a history of trauma to the knee while playing sports between April 2024 and April 2025. The two experienced radiologists reviewed the MRI examinations of these patients and reached a consensus regarding various MRI findings of different grades of ACL tears and their association with RAMP lesions. The Cohen's kappa (k) and Fisher's exact test statistics were used. RESULTS: Out of 252 patients with a sports injury to the knee and clinical suspicion of an acute ACL injury, 109 (43.3%) had an ACL injury and 27 had a RAMP lesion, with a prevalence of 10.7%. The RAMP lesion was seen only in patients with ACL injury and higher grades of ACL injury, i.e., Grade 2 and 3 were associated with RAMP lesion 11 (40.7%) and 10 (37.0%), respectively, although statistically not significant ( P = 0.291). CONCLUSION: Out of 252 patients with sports-related injuries to the knee with clinical suspicion of ACL injury, only 43.3% had ACL injuries and RAMP lesions have a prevalence of 10.7% (27) of all the patients with acute ACL injury. The strong association with ACL injury and having a potentially important role in knee stabilisation, their injuries need to be given due importance by radiologists and should not be underreported.
