This study aims to examine the relationship between foot angles and the presence and localization of osteochondral lesions of the talus (OLTs).
Between January 2014 and January 2019, a total of 152 patients with a diagnosis of medial OTLs (95 males, 57 females; mean age: 28.8±6.4 years; range, 18 to 40 years), 51 patients with a diagnosis of lateral OTLs (36 males, 15 females; mean age: 27.1±6.2 years; range, 18 to 39 years), and 114 patients without known foot-ankle trauma as the control group (56 males, 58 females; mean age: 29.0±6.1 years; range, 18 to 40 years) were included. Magnetic resonance imaging and radiographs of each group were analyzed retrospectively. Lateral talocalcaneal angle (LTCA), calcaneal inclination angle (CIA), Böhler angle (BA), and Gissane angle (GA) were measured on the images and the values were compared among the groups.
The CIA had a significant relationship with the localization (p<0.001). It was higher in patients with OLTs and had an effect on localization. The mean CIA was 26.6º±3.9º in the medial OLTs group, 23.0º±3.5º in the lateral OLTs group, and 18.5º±3.6º in the control group. There was a significant difference in the LTCA between the control and OLTs groups (p<0.001). The LTCA was higher in patients with OLTs, but had no effect on localization. The mean LTCA was 41.1º±4.2º for medial OLTs, 41.3º±4.2º for lateral OLTs, and 35.7º±6.8º for the controls. No significant relationship was found for BA and GA among the three groups.
Factors affecting the localization of OLTs are still not fully understood. However, foot morphology seems to play a role in determining medial or lateral localization. The LTCA is not related to the localization of OLTs; however, an increased LTCA may be related to the occurrence of OLTS. Increased CIA may be related to both OLTS localization and OLTs occurrence.
本研究旨在探讨足角与距骨骨软骨损伤（OLTs）的存在和定位之间的关系。
本研究共纳入了 152 例内侧 OLTs（95 例男性，57 例女性；平均年龄：28.8±6.4 岁；范围：18 岁至 40 岁）、51 例外侧 OLTs（36 例男性，15 例女性；平均年龄：27.1±6.2 岁；范围：18 岁至 39 岁）和 114 例无已知足踝创伤的对照组（56 例男性，58 例女性；平均年龄：29.0±6.1 岁；范围：18 岁至 40 岁）患者。回顾性分析了每组患者的磁共振成像和 X 线片。在图像上测量了外侧距跟角（LTCA）、跟骨倾斜角（CIA）、Böhler 角（BA）和 Gissane 角（GA），并比较了各组之间的差异。
CIA 与定位有显著关系（p<0.001）。OLTs 患者的 CIA 较高，且对定位有影响。内侧 OLTs 组的平均 CIA 为 26.6º±3.9º，外侧 OLTs 组为 23.0º±3.5º，对照组为 18.5º±3.6º。OLTs 组和对照组之间的 LTCA 差异有统计学意义（p<0.001）。OLTs 患者的 LTCA 较高，但对定位无影响。内侧 OLTs 的平均 LTCA 为 41.1º±4.2º，外侧 OLTs 为 41.3º±4.2º，对照组为 35.7º±6.8º。三组之间 BA 和 GA 无显著关系。
影响 OLTs 定位的因素仍不完全清楚。然而，足形态似乎在确定内侧或外侧定位方面发挥作用。LTCA 与 OLTs 的定位无关；然而，增加的 LTCA 可能与 OLTS 的发生有关。增加的 CIA 可能与 OLTS 的定位和发生都有关。
