Abstract：
UNASSIGNED: The aim of the study was to explore if the patellar tendon angles (PTAs) is an intrinsic risk factor for anterior cruciate ligament (ACL) rupture. We hypothesised that the PTAs will be increased in ACL rupture patients compared to matched controls.
UNASSIGNED: We performed a retrospective radiographic cohort study. A cohort of ACL-injured patients between 2019 and 2022 was utilised. The control population, from the same time period, was a consecutive series of 100 patients without ligament or meniscal injuries which were prospectively added to our institutional registry. Posterior tibial slope (PTS), static anterior tibial translation (SATT), patellar tendon to tibial plateau angle (PT-TPA), patellar tendon-tibial shaft angle (PT-TSA) were measured.
UNASSIGNED: A total of 100 patients were included in the control cohort and 110 in the ACL cohort. The PT-TPA was significantly less in the ACL cohort compared to the control cohort, mean and SD of 15.33 (±5.74) versus 13.91 (±5.68), respectively (p = 0.01). PT-TSA was also less in the ACL cohort, mean and SD of 116.15 (±5.89) versus 114.27 (±4.81), however, this failed to reach statistical significance (p = 0.08). The PT-TPA was not correlated with PTS (p = 0.65) and the PT-TSA was inversely correlated with PTS; Pearson correlation coefficient of -0.28 (p < 0.01). The PT-TSA had a greater correlation -0.4 (p < 0.01) with SATT than PTS 0.37 (p < 0.01).
UNASSIGNED: PTAs are not elevated in ACL-injured subjects. While anteriorisation of the tibial tubercle is utilised in dogs to decrease the anterior thrust resulting from the anteriorly directed vector of the quadriceps, this treatment in the humans is not warranted and methods to reduce the PTAs should focus on prehabilitation and rehabilitation.
UNASSIGNED: Level III.

摘要：
■本研究的目的是探讨髌腱角度（PTAs）是否是前交叉韧带（ACL）断裂的内在危险因素。我们假设与匹配的对照组相比，ACL破裂患者的PTA将增加。
■我们进行了一项回顾性影像学队列研究。使用了2019年至2022年的一组ACL损伤患者。控制人口，从同一时期，是连续100例没有韧带或半月板损伤的患者，这些患者被前瞻性地添加到我们的机构注册中。胫骨后斜坡(PTS),静态胫骨前平移（SATT），髌腱至胫骨平台角(PT-TPA),测量髌腱-胫骨干角(PT-TSA)。
■共有100名患者纳入对照队列，110名患者纳入ACL队列。与对照组相比，ACL队列中的PT-TPA明显较少，平均值和SD分别为15.33(±5.74)和13.91(±5.68)，分别(p=0.01)。PT-TSA在ACL队列中也较少，平均值和标准差分别为116.15(±5.89)和114.27(±4.81)，然而,这未能达到统计学意义(p=0.08)。PT-TPA与PTS无相关性(p=0.65),PT-TSA与PTS呈负相关,Pearson相关系数为-0.28(p<0.01)。PT-TSA与SATT的相关性-0.4(p<0.01)大于PTS0.37(p<0.01)。
■在受ACL损伤的受试者中PTA没有升高。虽然在狗中使用胫骨结节的前向化以减少由于股四头肌的前向矢量引起的前推力，这种治疗在人类中是没有必要的,减少PTA的方法应该集中在康复和康复上.
