BACKGROUND
The purpose of this study was (a) to investigate the association between the potential anatomical risk factors and medial meniscus posterior root tears (MMPRTs), and (b) to determine the optimal cutoff values of risk factors for discriminating MMPRTs.
METHODS
A retrospective study was conducted, from January 2018 to January 2020, 86 patients with MMPRTs identified by an experienced musculoskeletal radiologist using 3-T magnetic resonance imaging (MRI), and also confirmed during arthroscopic surgery were included in this study. Moreover, MMPRTs patients were matched with 128 patients with other types of medial meniscal tear knees at the same period according to patients' demographics. We categorized the two patient groups into subgroups based on the causes of meniscus root tears. A subgroup analysis was performed to evaluate the parameter differences between traumatic and degenerative MMPRT in these groups. The associations between clinical and anatomic factors and MMPRTs were analyzed. Additionally, a logistic regression analysis was performed to detect risk factors correlated with MMPRTs.
RESULTS
Based on the analysis, binary logistic regression models analysis indicated that medial posterior tibial slope (MTS) (odds ratio (OR) = 1.212, P = 0.005), hip knee ankle (HKA) (OR = 1.657, P < 0.001) and medial femoral condyle length/medial tibial plateau length (MFCL/MTPL) (OR = 16.597, P = 0.019) were the risk factors correlated with MMPRTs. A subgroup analysis revealed that the MTS, HKA, and MFCL/MTPL were risk factors associated with traumatic MMPRTs. Additionally, age, MTS, HKA, and MFCL/MTPL were identified as risk factors linked to degenerative MMPRTs. Additionally, the receiver operating characteristic (ROC) curves demonstrated these factors had comparable accuracy at predicting MMPRTs (under the curve were 0.635, 0.700 and 0.627, respectively). The cutoff values of those factors were 7.4º, 2.4º, and 1.2, respectively.
CONCLUSIONS
Based on results from the current study, we identified MTS > 7.4º, HKA > 2.4º and MFCL/MTPL > 1.2 were the risk factors correlated with MMPRTs.
背景
本研究的目的是：（a）调查潜在解剖学危险因素与内侧半月板后根撕裂（MMPRT）之间的关联；（b）确定用于鉴别MMPRT的危险因素的最佳截断值。
方法
进行了一项回顾性研究，纳入了2018年1月至2020年1月期间86例经经验丰富的肌肉骨骼放射科医生使用3-T磁共振成像（MRI）确诊且在关节镜手术中也得到证实的MMPRT患者。此外，根据患者人口统计学特征，将MMPRT患者与同期128例其他类型内侧半月板撕裂膝关节患者进行匹配。我们根据半月板根部撕裂的原因将两组患者分为亚组。进行亚组分析以评估这些组中创伤性和退变性MMPRT之间的参数差异。分析临床和解剖学因素与MMPRT之间的关联。此外，进行逻辑回归分析以检测与MMPRT相关的危险因素。
结果
基于分析，二元逻辑回归模型分析表明，胫骨后内侧坡度（MTS）（比值比（OR）=1.212，P=0.005）、髋膝踝角（HKA）（OR=1.657，P<0.001）以及股骨内侧髁长度/胫骨内侧平台长度（MFCL/MTPL）（OR=16.597，P=0.019）是与MMPRT相关的危险因素。亚组分析显示，MTS、HKA和MFCL/MTPL是与创伤性MMPRT相关的危险因素。此外，年龄、MTS、HKA和MFCL/MTPL被确定为与退变性MMPRT相关的危险因素。此外，受试者工作特征（ROC）曲线表明这些因素在预测MMPRT方面具有相当的准确性（曲线下面积分别为0.635、0.700和0.627）。这些因素的截断值分别为7.4°、2.4°和1.2。
结论
基于本研究结果，我们确定MTS>7.4°、HKA>2.4°和MFCL/MTPL>1.2是与MMPRT相关的危险因素。
