摘要

目的通过测量并对比复发性髌骨脱位患者与正常人群外侧胫骨平台后倾角（LPTS）、内侧胫骨平台后倾角（MPTS）和胫骨扭转角（TTA），分析LPTS、MPTS和TTA与复发性髌骨脱位之间的相关性。方法选取2019年7月~2021年6月就诊的33例（44膝）复发性髌骨脱位患者，列为研究组；另外选择同一时期因怀疑有髂血管、下肢血管疾病就诊的23例（46膝）受试者，列为对照组。所有纳入本研究的受试者均有下肢全长CT数据，使用Mimics 21.0软件重建三维模型，导入3-Matic软件中，测量并比较两组LPTS、MPTS和TTA。结果研究组LPTS、MPTS和TTA分别为（7.69±1.42）°、（10.06±1.71）°和（36.42±8.13）°，对照组LPTS、MPTS和TTA分别为（8.42±1.65）°、（10.44±0.86）°和（25.77±3.90）°；研究组与对照组之间比较，不同性别、侧别之间LPTS、MPTS和TTA差异均无统计学意义（P>0.05）；研究组与对照组相比，LPTS偏小，差异有统计学意义（P<0.05）；研究组MPTS与对照组相比，差异无统计学意义（P>0.05）；研究组与对照组相比，TTA偏大，差异有统计学意义（P<0.05）；研究组与对照组相比，LPTS和MPTS不对称性偏大，差异有统计学意义（P<0.05）。结论复发性髌骨脱位患者外侧胫骨平台后倾角与正常人群相比偏小，而内侧胫骨平台后倾角无差异；复发性髌骨脱位患者胫骨扭转角较正常人偏大；外侧胫骨平台后倾角和胫骨扭转角与复发性髌骨脱位存在一定相关性，对复发性髌骨脱位具有一定的诊断能力。

Abstract

Objective To measure and compare the lateral posterior tibial slope (LPTS), medial posterior tibial slope (MPTS) and tibial torsion angle (TTA) between the patients of recurrent patellar dislocation and the heathy people, and to analyze the correlation between LPTS, MPTS and TTA and the risk factors of recurrent patellar dislocation. Methods A total of 33 patients (44 knees) with recurrent patellar dislocation in our hospital from July 2019 to June 2021 were selected and listed as the study group. Twenty-three subjects (46 knees) who were suspected iliac vascular and lower limb vascular diseases during the same period were selected and listed as the control group. All the enrolled researchers had full-length CT scans date of the lower limbs. Three-dimensional models were reconstructed using Mimics 21.0 software and then imported into 3-matic software. The LPTS, MPTS and TTA were measured and compared between the two groups. Results In the study group, the LPTS, MPTS and TTA were （7.69±1.42）°,（10.06±1.71）°,（36.42±8.13）°, respectively, while the control group, the LPTS, MPTS and TTA were（8.42±1.65）°, （10.44±0.86）°, (25.77±3.90)°, respectively. There were no significant differences in the LPTS, MPTS and TTA between different genders and sides both in the study group and the control group (P>0.05). Compared with the control group, the LPTS in the study group was smaller, and the difference was statistically significant (P<0.05). There was no statistically significant difference between the study group and the control group in the MPTS (P>0.05). Compared with the control group, the TTA in the study group was higher, and the difference was statistically significant (P<0.05). Compared with the control group, the LPTS and MPTS in the study group were significant asymmetry, and the difference was statistically significant (P<0.05). Conclusion The lateral posterior tibial slope of patients with recurrent patellar dislocation is significantly smaller than that in the healthy people, while there is no significant difference in the medial posterior tibial slope; The tibial torsion angle of patients with recurrent patellar dislocation is significantly larger than in the healthy people; The lateral posterior tibial slope and tibial torsion angle have certain correlation with recurrent patellar dislocation, which can conduct the diagnosis of recurrent patellar dislocation.
