目的本研究旨在利用股骨滑车的三维磁共振图像重建来阐明男性和女性滑车形态的主要差异。方法对975例患者（女性825例，男性150例）股骨滑车人体测量资料进行对比分析。在股骨滑车的三个屈曲角度（15度、30度和45度）测量以下形态学参数：沟角、髁突高度、滑车沟方向和中外侧沟位置。结果15°和45°屈曲时，女性的沟角明显大于男性（P < 0.05）。然而，在30度屈曲时的沟角没有发现性别差异。在三个屈曲角度上，男性的内外侧髁高度值大于女性（P < 0.01）。滑车沟方向和中外侧沟位置无性别差异。结论磁共振图像重建显示男女滑车形态测量差异显著。考虑到韩国人口的性别差异，本研究为设计适合全膝关节置换术的股骨假体提供了指导。我们的发现可以优化韩国个体全膝关节置换术的生物力学指南，从而降低髌骨脱位的风险。外科医生应注意股骨滑车的性别差异，以优化植入物的选择。
Purpose This study aimed to elucidate the primary differences in trochlear morphology between men and women utilizing three-dimensional magnetic resonance image reconstruction of the femoral trochlea. Methods Differences in anthropometric femoral trochlea data of 975 patients (825 women, 150 men) were evaluated. The following morphological parameters were measured at three flexion angles (15 degrees, 30 degrees, and 45 degrees) of the femoral trochlea: the sulcus angle, condylar height, and the trochlear groove orientation and mediolateral groove position. Results The sulcus angle was significantly greater in women than in men at 15 degrees and 45 degrees flexions (P < 0.05). However, there was no gender difference found in the sulcus angle at 30 degrees flexion. Medial and lateral condylar height values were greater in men than in women for the three flexion angles (P < 0.01). The trochlear groove orientation and mediolateral groove position showed no gender-related differences. Conclusions Magnetic resonance image reconstruction demonstrated that measurement of trochlear morphology varied significantly between men and women. This study provides guidelines for the design of a suitable femoral component for total knee arthroplasty, considering gender-specific differences in the Korean population. Biomechanical guidelines for total knee arthroplasty in Korean individuals can be optimized using our finding, so as the risk of patellar dislocation to be decreased. Surgeons should be aware of gender differences in femoral trochlear to optimize choice of implant.
