摘要

目的研究胫骨结节-韧带沟（TT-TG）距离与髌腱长度之间的关系。方法回顾性审查了2018年7月至2019年6月期间在一家机构接受前交叉韧带重建术并有膝关节磁共振成像（MRI）研究存档的所有健康运动员。排除标准包括没有存档膝关节核磁共振成像研究或核磁共振成像质量不高，无法可靠计算TT-TG和髌腱长度的患者。核磁共振成像检查用于计算TT-TG、髌腱长度和卡顿-德尚指数（CDI）。查看患者病历以获得人体测量特征，包括性别、并发症、既往膝关节手术以及 MRI 检查时的年龄。斯皮尔曼相关性用于评估TT-TG、髌腱长度和CDI之间的关系，回归分析用于评估TT-TG、髌腱长度和患者特异性因素之间的关系。结果共纳入235名患者（99名女性[42.1%]，136名男性[57.9%]；平均年龄：30.0岁[23.0；40.0]）。TT-TG 和髌腱长度的两位评审员之间的评分间可靠性分别为 0.888 和 0.804，CDI 为 0.748，显示出很高的一致性。TT-TG 与髌腱长度的相关性为 0.021，表明两者之间没有真正的关系。TT-TG与CDI的相关性为-0.048，髌腱长度与CDI的相关性为0.411，表明两者之间存在微弱的正相关关系。回归分析发现，男性性别与较长的髌腱长度密切相关（几率比 2.65，95% 置信区间 1.33-3.97，P <.001）。男性性别与较长的髌骨长度相关。

Tibial Tubercle Trochlear Groove Distance Does Not Correlate With Patellar Tendon Length in Patients Who Underwent Anterior Cruciate Ligament Reconstruction

Purpose

To examine the relationship between tibial tubercle–trochlear groove (TT-TG) distance and patellar tendon length.

Methods

All healthy athletes who underwent anterior cruciate ligament reconstruction who had a magnetic resonance imaging (MRI) study of the knee on file between July 2018 and June 2019 at a single institution were retrospectively reviewed. Exclusion criteria included patients without an MRI study of the knee on file or with an MRI of insufficient quality precluding reliable calculation of TT-TG and patellar tendon length. MRIs were reviewed to calculate TT-TG, patellar tendon length, and Caton–Deschamps Index (CDI). Patient charts were reviewed to obtain anthropometric characteristics including sex, concomitant injuries, and previous knee procedures as well as age at time of MRI. Spearman correlations were used to assess the relationship between TT-TG, patellar tendon length, and CDI, with regression analysis performed to assess for relationships between TT-TG, patellar tendon length, and patient-specific factors.

Results

Overall, 235 patients (99 female [42.1%], 136 male [57.9%]; mean age: 30.0 years [23.0; 40.0]) were included. Inter-rater reliability between the 2 reviewers was 0.888 for TT-TG, 0.804 for patellar tendon length, and 0.748 for CDI, indicating strong agreement. The correlation between TT-TG and patellar tendon length was 0.021, indicating no true relationship. The correlation between TT-TG and CDI was –0.048 and that of patellar tendon length and CDI was 0.411, indicating a weak positive relationship. Regression analysis found that male sex is strongly correlated with a longer patellar tendon length (odds ratio 2.65, 95% confidence interval 1.33-3.97, P < .001).
