本横断面研究的目的是评估自然前交叉韧带（ACL）在矢状面和冠状面的倾斜角度，并根据性别、身高、BMI和骨骼成熟度评估这些结果，本研究的纳入标准包括在一个门诊骨科中心接受常规膝关节磁共振成像（MRI）的患者，MRI显示ACL完整。在MRI矢状面和冠状面上测量倾斜角度。根据性别、身高、BMI和骨骼成熟度对患者进行比较，共纳入188例患者（36例骨骼未成熟/152例骨骼成熟; 98例男性/90例女性）。冠状面的总体倾斜角为74.3A度+/- 4.8A度，矢状面为46.9A度+/- 4.9A度。骨骼不成熟患者（冠状面：71.8A度A +/- 6.1A度;矢状面：44.7A度A +/- 5.5A度）在冠状面和矢状面均存在显著差异（分别为P = 0.04和0.01），来自成熟的患者（冠状面：75.3A度A +/- 4.7A度;矢状面：47.4A度A +/- 4.7A度）。性别、身高或BMI无差异，本研究中的倾斜角度结果与其他研究存在差异，这可能是由于MRI和测量技术。在临床上，当使用ACL倾斜角来评估解剖ACL重建时，骨骼成熟度可能很重要。预后回顾性研究，证据等级III。
The purpose of this cross-sectional study was to evaluate the angle of inclination of the native anterior cruciate ligament (ACL) in both the sagittal and coronal planes and to evaluate these findings based on sex, height, BMI, and skeletal maturity.Inclusion criteria for the study included patients undergoing routine magnetic resonance imaging (MRI) of the knee at a single outpatient orthopedic center who had an intact ACL on MRI. Measurements of the angle of inclination were made on MRIs in both the sagittal and coronal planes. Patients were compared based on sex, height, BMI, and skeletal maturity.One-hundred and eighty-eight patients were included (36 skeletally immature/152 skeletally mature; 98 male/90 female). The overall angle of inclination was 74.3A degrees +/- 4.8A degrees in the coronal plane and 46.9A degrees +/- 4.9A degrees in the sagittal plane. Skeletally immature patients (coronal: 71.8A degrees A +/- 6.1A degrees; sagittal: 44.7A degrees A +/- 5.5A degrees) were significantly different in both coronal and sagittal planes (P = 0.04 and 0.01, respectively) from skeletally mature patients (coronal: 75.3A degrees A +/- 4.7A degrees; sagittal: 47.4A degrees A +/- 4.7A degrees). There were no differences based on sex, height, or BMI.There are differences between the angle of inclination findings in this study and other studies, which could be due to MRI and measurement techniques. Clinically, skeletal maturity may be important to account for when using the ACL angle of inclination to evaluate anatomic ACL reconstruction.Prognostic retrospective study, Level of evidence III.
