Meniscal tears are one of the most common knee injuries. Partial meniscectomy and meniscal repair are the most common treatment options in the setting of an unstable meniscal tear. Standard MR diagnostic criteria of a meniscal tear may be normal findings postoperatively. The diagnosis of a recurrent or residual meniscal tear after prior meniscal surgery is primarily based on the visualization of surfacing high meniscal T2-weighted signal. After meniscectomy of greater than 25%, or meniscal repair, MR arthrography may be of benefit in the accurate evaluation of a possible residual or recurrent meniscal tear.
半月板撕裂是最常见的膝关节损伤之一。在不稳定的半月板撕裂情况下，半月板部分切除术和半月板修复术是最常见的治疗选择。标准的 MRI 诊断半月板撕裂的标准可能在手术后为正常发现。既往半月板手术后复发或残留半月板撕裂的诊断主要基于表面高 T2 加权信号的半月板可视化。半月板切除超过 25%或半月板修复后，磁共振关节造影术可能有助于准确评估可能存在的残留或复发半月板撕裂。
