摘要

背景:髌骨不稳是一种众所周知的病理现象,其运动学指标包括胫骨结节气管沟(TTTG)、髌骨平分偏移(BO)和髌骨外侧倾斜(LPT)。我们使用动态计算机断层扫描(CT)来研究健康受试者在负重条件下的髌骨运动,以提供 TTTG、BO 和 LPT 的标准值,并确定 BO 和 LPT 是否受胫骨结节气管沟形态的影响:方法:对 21 名成年健康志愿者进行动态扫描,获取其负重时的图像。在膝关节屈曲 0° 和 30° 之间计算 TTTG、BO 和 LPT 指标。计算出沟角度、沟深度和外侧套骨倾斜度,并与 TTTG 一起用于简单线性回归模型:在偏心运动过程中,所有指标都逐渐下降(TTTG,-6.9 mm;BO,-12.6%;LPT,-4.3°)。在任何屈曲角度下,偏心和同心阶段的所有指标均无明显差异。完全伸展运动指标之间的线性回归显示,BO 和 TTTG(R2 0.60,β 1.75)以及 BO 和 LPT(R2 0.59,β 1.49)之间的拟合度适中,而 TTTG 和 LPT 之间的拟合度较低(R2 0.38,β 0.53)。男性参与者(R2 0.71,β 1.89)和髌骨畸形者(R2 0.55,β 1.91)的 TTTG 距离对 BO 的影响较大:我们提供了负重动态 CT 中三个常见指标的初步标准值,并显示了髌骨肌腱外侧化对髌骨位移的重大影响:这些标准值可供临床医生在使用 TTTG、BO 和 LPT 指标评估膝关节患者时使用。髌骨外翻或男性患者的髌骨肌腱外侧化对髌骨外侧移位有显著影响:关键点:韧带沟形态对运动预测没有实质性影响。髌骨肌腱的外侧化似乎对男性受试者的髌骨外侧位移有很大的预测作用。髌骨外翻的参与者的髌骨外侧位移与倾斜度之间有很强的拟合。在同心运动时,TTTG、BO 和 LPT 均有所下降。同心和偏心阶段的所有指标均无差异。

Investigating patellar motion using weight-bearing dynamic CT: normative values and morphological considerations for healthy volunteers.

Background: Patellar instability is a well-known pathology in which kinematics can be investigated using metrics such as tibial tuberosity tracheal groove (TTTG), the bisect offset (BO), and the lateral patellar tilt (LPT). We used dynamic computed tomography (CT) to investigate the patellar motion of healthy subjects in weight-bearing conditions to provide normative values for TTTG, BO, and LPT, as well as to define whether BO and LPT are affected by the morphology of the trochlear groove.

Methods: Dynamic scanning was used to acquire images during weight-bearing in 21 adult healthy volunteers. TTTG, BO, and LPT metrics were computed between 0° and 30° of knee flexion. Sulcus angle, sulcus depth, and lateral trochlear inclination were calculated and used with the TTTG for simple linear regression models.

Results: All metrics gradually decreased during eccentric movement (TTTG, -6.9 mm; BO, -12.6%; LPT, -4.3°). No significant differences were observed between eccentric and concentric phases at any flexion angle for all metrics. Linear regression between kinematic metrics towards full extension showed a moderate fit between BO and TTTG (R2 0.60, β 1.75) and BO and LPT (R2 0.59, β 1.49), and a low fit between TTTG and LPT (R2 0.38, β 0.53). A high impact of the TTTG distance over BO was shown in male participants (R2 0.71, β 1.89) and patella alta individuals (R2 0.55, β 1.91).

Conclusion: We provided preliminary normative values of three common metrics during weight-bearing dynamic CT and showed the substantial impact of lateralisation of the patella tendon over patella displacement.

Relevance statement: These normative values can be used by clinicians when evaluating knee patients using TTTG, BO, and LPT metrics. The lateralisation of the patellar tendon in subjects with patella alta or in males significantly impacts the lateral displacement of the patella.

Key points: Trochlear groove morphology had no substantial impact on motion prediction. The lateralisation of the patellar tendon seems a strong predictor of lateral displacement of the patella in male participants. Participants with patella alta displayed a strong fit between the patellar lateral displacement and tilt. TTTG, BO, and LPT decreased during concentric movement. Concentric and eccentric phases did not show differences for all metrics.
