本研究的目的是确定胫骨平台关节面的几何形状是否与非接触性前交叉韧带（ACL）损伤相关。这是一项采用巢式病例对照分析的纵向队列研究。78名非接触性ACL撕裂受试者和相应数量的年龄、性别和运动匹配的对照组接受了双膝3 T MRI检查。胫骨关节软骨的表面几何形状的特点与多项式方程和比较膝盖之间的同一个人和ACL损伤和对照组。对照组受试者膝关节的表面几何形状无差异。相反，ACL损伤受试者的损伤和正常膝关节之间的表面几何形状存在显着差异，表明ACL损伤改变了软骨表面轮廓。因此，将ACL损伤受试者的未损伤膝关节与其匹配对照的相应膝关节进行比较，结果显示内侧（p < 0.006）和外侧（p < 0.001）间室的表面几何形状存在显著差异。ACL损伤受试者倾向于表现出关节面相对于胫骨长轴的后下方定向，而对照受试者更可能表现出后上方定向。
The purpose of this study was to determine if geometry of the articular surfaces of the tibial plateau is associated with non-contact anterior cruciate ligament (ACL) injury. This was a longitudinal cohort study with a nested case-control analysis. Seventy-eight subjects who suffered a non-contact ACL tear and a corresponding number of controls matched by age, sex, and sport underwent 3 T MRI of both knees. Surface geometry of the tibial articular cartilage was characterized with polynomial equations and comparisons were made between knees on the same person and between ACL-injured and control subjects. There was no difference in surface geometry between the knees of the control subjects. In contrast, there were significant differences in the surface geometry between the injured and normal knees of the ACL-injured subjects, suggesting that the ACL injury changed the cartilage surface profile. Therefore, comparisons were made between the uninjured knees of the ACL-injured subjects and the corresponding knees of their matched controls and this revealed significant differences in the surface geometry for the medial (p < 0.006) and lateral (p < 0.001) compartments. ACL-injured subjects tended to demonstrate a posterior-inferior directed orientation of the articular surface relative to the long axis of the tibia, while the control subjects were more likely to show a posterior-superior directed orientation.
