The purpose of this study was to assess, in anterior cruciate ligament (ACL)-injured and -uninjured population, tibial plateau anatomic variables [medial and lateral tibial plateau slopes (MTPS and LTPS) and medial tibial plateau depth (MTPD)] on conventional magnetic resonance imaging (MRI) using a novel combined method and to determine whether these variables are risk factors for ACL injury.
Seventy-three isolated ACL-injury patients (20 women and 53 men) were compared with 51 control group patients (19 women and 32 men).
The combined method had very high interrater and intrarater reliability compared with previously described methods. LTPS was significantly steeper in the overall injured group and injured men compared with the control group, with odds ratio (OR) of 3.031 and 5.89, respectively. Women with ACL injury had significantly shallower MTPD than uninjured women, with OR of 4.13.
We conclude that the new combined method is accurate and reproducible for assessing the tibial plateau anatomy. Women with shallower MTPD and men with steeper LTPS are at higher risk of sustaining ACL injury. Overall, steeper LTPS is a significant risk factor for sustaining ACL injury.
本研究旨在评估前交叉韧带(ACL)损伤和未损伤人群中胫骨平台解剖学变量[内侧和外侧胫骨平台斜率(MTPS 和 LTPS)和内侧胫骨平台深度(MTPD)]在常规磁共振成像(MRI)上的变化,并确定这些变量是否是 ACL 损伤的危险因素。
将 73 名孤立性 ACL 损伤患者(20 名女性和 53 名男性)与 51 名对照组患者(19 名女性和 32 名男性)进行比较。
与先前描述的方法相比,联合方法具有非常高的组内和组间可靠性。与对照组相比,整体损伤组和损伤男性的 LTPS 明显更陡峭,比值比(OR)分别为 3.031 和 5.89。与未受伤的女性相比,ACL 受伤的女性的 MTPD 明显较浅,OR 为 4.13。
我们得出结论,新的联合方法在评估胫骨平台解剖结构方面准确且可重复。MTPD 较浅的女性和 LTPS 较陡的男性更易发生 ACL 损伤。总的来说,LTPS 更陡峭是 ACL 损伤的一个显著危险因素。
