目的：内侧半月板后根撕裂（MMPRT）导致内侧半月板挤压（MME）进展。本研究旨在根据两次术前磁共振成像 (MRI) 扫描结果计算 MME 的进展率，并确定相关因素。 材料和方法：我们回顾性分析了 33 名患者（27 名女性和 6 名男性；平均年龄 60 岁），他们接受了两次 MRI，平均间隔为 48 天。我们测量了内侧半月板体宽度、内侧关节间隙宽度 (MJSW) 和 MME。 MME 进展率源自两次 MRI 扫描之间 MME 增加 (DeltaMME) 的回归分析。此外，还评估了 MME 增加率与年龄、体重指数、股胫角和 MJSW 的相关性。 结果：平均 MME 从 3.4 mm 增加到 4.5 mm（p
PURPOSE: Medial meniscus posterior root tear (MMPRT) causes progression of medial meniscus extrusion (MME). This study aims to calculate the progression rate of MME based on findings in two preoperative magnetic resonance imaging (MRI) scans and determine the associated factors.MATERIALS AND METHODS: We retrospectively reviewed 33 patients (27 females and 6 males; mean age, 60 years) who underwent MRI twice, at a mean interval of 48 days. We measured the medial meniscus body width, medial joint space width (MJSW), and MME. The MME progression rate was derived from regression analysis of the increase in MME (DeltaMME) between the two MRI scans. In addition, the correlations of the MME increase rate with age, body mass index, femorotibial angle, and MJSW were evaluated.RESULTS: The mean MME increased from 3.4 mm to 4.5 mm (p
