    荧光镜检查被认为是插入导管的金标准和基本要求。然而,关于超声(USG)引导下插入和不透视结果的数据很少.我们比较了在有和没有透视辅助的情况下插入USG引导的隧道透析导管(TDC)的并发症。
    这是一项在印度北部一家三级医院进行的单中心随机对照试验(RCT)。在筛查153名患者后,149人入选:87人随机进入USG引导下无透视插入(A组),62人随机进入USG引导下无透视插入(B组)。所有插入均由训练有素的肾脏科医师在专门的手术室中完成。在基线和1个月随访时分析结果。比较两组的机械性并发症以及感染性和血栓性并发症。
    所有研究参与者(N=149)的TDC插入均成功(100%)。在第一次尝试中插入了129根导管(86.5%),19(12.5%)在第二次尝试中,和一个导管插入需要三次尝试插入。研究参与者的平均年龄为43岁(±16.5),男性占研究队列的63%。两组的基线实验室特征具有可比性。导管插入时间A组为41.26min(标准差[SD]11.8),B组为47.74min(SD17.2)(P=0.007)。导管插入容易程度的平均评分,出口部位出血,感染性和机械性并发症两组间无差异。
    我们的研究得出结论,透视在减少机械,感染,或者血栓性并发症.在有经验的手中,没有透视辅助的USG引导的TDC插入与透视辅助的插入一样好。更短的手术时间。
    UNASSIGNED: Fluoroscopy is considered to be the gold standard and an essential requirement for catheter insertion. However, there is a paucity of data regarding the outcomes in ultrasound (USG)-guided insertion with and without fluoroscopy. We compared the complications of USG-guided tunneled dialysis catheter (TDC) insertion with and without fluoroscopy assistance.
    UNASSIGNED: This was a single-center randomized controlled trial (RCT) done in a tertiary hospital in North India. After screening 153 patients, 149 were enrolled: 87 were randomized into USG-guided insertion without fluoroscopy (group A) and 62 were randomized into USG-guided insertion with fluoroscopy (group B). All insertions were done in a dedicated procedure room by trained nephrologists. Outcomes were analyzed at baseline and at 1-month follow-up. Mechanical complications as well as infective and thrombotic complications were compared between both the groups.
    UNASSIGNED: TDC insertion was successful (100%) in all the study participants (N = 149). One hundred twenty-nine catheters (86.5%) were inserted in the first attempt, 19 (12.5%) in the second attempt, and one catheter insertion required three attempts for insertion. The mean age of study participants was 43 years (±16.5), and males constituted 63% of the study cohort. Baseline laboratory characteristics of the two groups were comparable. The mean time of catheter insertion was 41.26 min (standard deviation [SD] 11.8) in group A and 47.74 min (SD 17.2) in group B (P = 0.007). The mean score of ease of catheter insertion, exit site bleed, infective and mechanical complications were not different between the two groups.
    UNASSIGNED: Our study concluded that fluoroscopy has no additional advantage in reducing mechanical, infective, or thrombotic complications. In experienced hands, USG-guided TDC insertion without fluoroscopy assistance is as good as the insertion done with fluoroscopy assistance, with a shorter procedure time.

    背景:比较倒置内界膜(ILM)皮瓣技术和ILM插入术治疗高度近视无视网膜脱离的黄斑裂孔(MH)的手术效果。
    方法:在这项回顾性研究中,我们分析了2015年4月至2021年8月期间接受MH手术的22只眼轴长度≥30.0mm的眼.外科手术涉及倒置的ILM皮瓣或ILM插入。比较两种技术的结果。通过光学相干断层扫描(OCT)确认MH的闭合。在手术前后测量最佳矫正视力(BCVA)。记录相关并发症。
    结果:轴向长度的中位数为30.64mm(范围,30.0-34.42)。MH在100%(22/22)眼中闭合,并且没有复发,中位随访时间为12.5个月。对于倒置ILM皮瓣技术,中值BCVA从最小分辨率角(logMAR)的0.80对数显著提高(范围,0.40-2.00)术前为0.70logMAR(范围,手术后0.09-1.52)(p=0.002)。此外,倒置ILM皮瓣的最终BCVA中位数优于ILM插入(0.7logMARV.S.1.00logMAR;p=0.016)。
    结论:在高度近视的眼中,尽管ILM插入和倒置ILM皮瓣对MH闭合的影响相当,后一种技术取得了明显更好的视觉效果.
    BACKGROUND: To compare the surgical outcomes of the inverted internal limiting membrane (ILM) flap technique and ILM insertion for macular hole (MH) without retinal detachment in eyes with extremely high myopia.
    METHODS: In this retrospective study, we analyzed 22 eyes with an axial length ≥ 30.0 mm that had underwent MH surgery between April 2015 and August 2021. The surgical procedures involved either an inverted ILM flap or ILM insertion. The outcomes were compared between the two techniques. Closure of the MH was confirmed by optical coherence tomography (OCT). The best-corrected visual acuity (BCVA) was measured before and after surgery. Associated complications were documented.
    RESULTS: The median of axial length was 30.64 mm (range, 30.0-34.42). The MH closed in 100% (22/22) eyes and did not recur with a median follow-up of 12.5 months. For the inverted ILM flap technique, the median BCVA improved significantly from 0.80 logarithm of the minimum angle of resolution (logMAR) (range, 0.40-2.00) before surgery to 0.70 logMAR (range, 0.09-1.52) after surgery (p = 0.002). In addition, the median of final BCVA was better for the inverted ILM flap than ILM insertion (0.7 logMAR V.S. 1.00 logMAR; p = 0.016).
    CONCLUSIONS: In eyes with extremely high myopia, despite comparable effects on MH closure for both ILM insertion and the inverted ILM flap, the later technique achieved significantly better visual outcomes.

    目标:跟腱(AT)软骨层生长的组织学差异,股四头肌腱(QT),髌腱(PT),前交叉韧带(ACL)的插入尚不清楚。因此,本研究旨在探讨AT软骨层生长的差异,QT,PT,和ACL插入。材料与方法:采用48只雄性日本大白兔。在不同阶段(第1天和第1、2、4、6、8、12和24周)对6只动物实施安乐死。SafraninO-染色糖胺聚糖(GAG)生产区,软骨细胞计数,和插入宽度进行了调查。结果:双向方差分析(ANOVA)显示,所有参数的时间和插入的主要影响均存在显着差异。此外,时间×插入交互作用显著。多重比较显示ACL插入和所有其他变量之间存在显著差异;然而,QT的GAG生产面积没有显著差异,PT,和AT插入。AT插入与所有其他组明显不同;然而,ACL的软骨细胞数量和插入宽度没有显着差异,QT,和PT插入。结论:AT之间的软骨层生长不同,QT,PT,和ACL插入。插入之间的差异也可能是由于其结构的差异,地点,和机械环境。
    Objectives: Histological differences in cartilage layer growth in Achilles tendon (AT), quadriceps tendon (QT), patellar tendon (PT), and anterior cruciate ligament (ACL) insertion are unclear. Therefore, this study aimed to investigate the differences in cartilage layer growth in AT, QT, PT, and ACL insertions. Materials and Methods: Forty-eight male Japanese white rabbits were used. Six animals were euthanized at different stages (day 1 and 1, 2, 4, 6, 8, 12, and 24 weeks). Safranin O-stained glycosaminoglycan (GAG) production area, chondrocyte count, and insertion width were investigated. Results: A two-way analysis of variance (ANOVA) revealed a significant difference in the main effects of time and insertion for all parameters. In addition, the time × insertion interaction was significant. Multiple comparisons showed a significant difference between the ACL insertion and all other variables; however, the GAG production area was not significantly different for the QT, PT, and AT insertions. AT insertions were significantly different from all other groups; however, the number of chondrocytes and insertion width were not significantly different for ACL, QT, and PT insertions. Conclusion: Cartilage layer growth differed between the AT, QT, PT, and ACL insertions. The differences between the insertions may also be due to the differences in their structures, locations, and mechanical environments.

    我们旨在确定2型糖尿病患者中ACE插入/缺失基因多态性的分布及其与肾病生物标志物和代谢指标的关联。
    数据收集了在Mbarara地区转诊医院的糖尿病诊所接受医疗保健的237名成人2型糖尿病患者。使用常规PCR技术扩增外周血基因组DNA,并分析ACE纯合形式的插入(II),缺失(DD)和杂合插入缺失(ID)基因型以及它们各自的等位基因计数。使用系统兼容的试剂在BeckmancoulterAU480化学分析仪上分析肾病的生物标志物。
    大多数参与者是老年人(中位数=57,IQR=49-64)和女性171(72.2%)。他们中的大多数具有缺失等位基因198(83.5%)和DD基因型116(48.9%)。在多变量逻辑回归中,肾病的生物标志物是微量白蛋白尿,血清肌酐,尿素,eGFR和电解质与ACEI/D等位基因或基因型无关(p>0.05)。另一方面,选定的代谢指标呈正相关。插入等位基因与糖化血红蛋白增加(OR=1.082,p=0.019)和血清葡萄糖水平降低(OR=0.891,p=0.001)相关。等位基因缺失与糖化血红蛋白降低(OR=0.924,p=0.047)和血清葡萄糖水平升高(OR=1.208,p=0.001)相关。ACEII基因型与血清葡萄糖水平降低相关(OR=0.873,p=0.029)。ACEDD基因型与糖化血红蛋白降低(OR=0.917,p=0.010)和血糖升高(OR=1.132,p=0.001)相关。ACEID基因型与糖化血红蛋白升高相关(OR=1.077,p=0.022),甘油三酯水平(OR=1.316,p=0.031)和降低血清葡萄糖水平(OR=0.933,p=0.038)。
    ACEI/D等位基因和基因型的存在或不存在会影响血清葡萄糖的最终升高或降低,糖化血红蛋白和甘油三酯水平。尽管肾病的生物标志物与ACEI/D等位基因或基因型之间没有显著关联,上述涉及的代谢指标应纳入2型糖尿病患者的医疗指南.
    UNASSIGNED: We aimed at determining the distribution of the ACE insertion/deletion gene polymorphisms among type 2 diabetic patients and their association with the nephropathy biomarkers and the metabolic indicators.
    UNASSIGNED: Data were collected from 237 adult type 2 diabetes mellitus patients receiving healthcare at the diabetic clinic of Mbarara Regional Referral Hospital. Peripheral blood genomic DNA was amplified using a conventional PCR technique and analyzed for the ACE homozygous forms of the insertion (II), deletion (DD) and heterozygous insertion deletion (ID) genotypes as well as their respective allele counts. Biomarkers of nephropathy were analyzed on a Beckman coulter AU480 chemistry analyzer using system compatible reagents.
    UNASSIGNED: Majority of the participants were older persons (Median = 57, IQR = 49-64) and female 171 (72.2%). Most of them had the Deletion allele 198 (83.5%) and DD genotype 116 (48.9%). At multivariate logistic regression, the nephropathy biomarkers that is microalbuminuria, serum creatinine, urea, eGFR and electrolytes had no association with the ACE I/D alleles or genotypes (p > 0.05). On the other hand, selected metabolic indicators had a positive relationship. The insertion allele was associated with increasing glycated hemoglobin (OR = 1.082, p = 0.019) and decreasing serum glucose levels (OR = 0.891, p = 0.001). Deletion allele was associated with decreasing glycated hemoglobin (OR = 0.924, p = 0.047) and increasing serum glucose levels (OR = 1.208, p = 0.001). ACE II genotype was associated with decreasing serum glucose levels (OR = 0.873, p = 0.029). ACE DD genotype was associated with decreasing glycated hemoglobin (OR = 0.917, p = 0.010) and increasing serum glucose levels (OR = 1.132, p = 0.001). ACE ID genotype was associated with increasing glycated hemoglobin (OR = 1.077, p = 0.022), triglyceride levels (OR = 1.316, p = 0.031) and decreasing serum glucose levels (OR = 0.933, p = 0.038).
    UNASSIGNED: The presence or absence of the ACE I/D alleles and genotypes affects the ultimate increase or decrease in the serum glucose, glycated hemoglobin and triglyceride levels. Although there was no significant association between the biomarkers of nephropathy and the ACE I/D alleles or genotypes, the above implicated metabolic indicators should be included in healthcare guidelines used when attending to type 2 diabetic patients.

    背景:多汗性外胚层发育不良(HED)是一种导致外胚层结构异常发育的遗传性疾病。这种罕见的情况主要影响头发,指甲,内分泌腺体,和牙齿。虽然HED可以由多种基因引起,EDA,EDAR,EDARADD,WNT10A基因约占病例的90%。值得注意的是,与EDA中的变体相关的HED形式,EDAR,或EDARADD基因可能由于常见信号通路的缺陷而表现出相似的表型。这些基因产物之间的适当相互作用对于核因子(NF-κB)信号通路的激活至关重要,随后调节目标基因的转录。EDARADD基因,特别是,藏有与HED相关的最罕见的变种之一。
    方法:在Sanliurfa培训和研究医院的门诊医学遗传学诊所,对父母近亲出生的5岁和2岁的兄弟进行了检查,土耳其。两者都表现出相同的HED经典表型特征。老人的头发很稀疏,又黑又脆,稀疏的眉毛和睫毛,锥形上、下前磨牙,有牙体发育不全,宽间隔的牙齿,皮肤非常干燥,轻度突出的前额,和眶周皱纹。年轻的那个显示了同样的,但不那么严重,临床特征。经过全面检查和病史评估,靶向下一代测序分析在EDARADD中产生了新的纯合插入变体c.322_323insCGGGCp。(Arg108ProfsTer7)。该突变迄今为止在文献中没有报道。
    结论:在本报告中,我们展示了两个兄弟姐妹表现出经典的HED症状和一个新的EDARADD基因插入变体,这导致移码引入终止密码子。两兄弟都从父母那里继承了这种突变,他们是相同变体的杂合携带者。本研究可能揭示了HED的致病机制,并扩大与这种情况相关的EDARADD基因变异的范围。
    BACKGROUND: Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder that results in the abnormal development of structures derived from ectodermal tissue. This rare condition predominantly affects the hair, nails, eccrine glands, and teeth. While HED can be caused by various genes, the EDA, EDAR, EDARADD, and WNT10A genes account for approximately 90% of cases. Notably, HED forms associated with variants in the EDA, EDAR, or EDARADD genes may exhibit similar phenotypes due to defects in a common signaling pathway. Proper interaction among the products of these genes is crucial for the activation of the nuclear factor (NF-κB) signaling pathway, which subsequently regulates the transcription of targeted genes. The EDARADD gene, in particular, harbors one of the rarest reported variants associated with HED.
    METHODS: Five-and two-years-old brothers born into consanguineous parents were examined at our outpatient medical genetics clinic at Sanliurfa Training and Research Hospital, Turkey. Both displayed the same classical phenotypic features of HED. The elder had a very sparse dark and brittle hair, sparse eyebrows and eyelashes, conical upper and lower premolar teeth with hypodontia, widely spaced teeth, very dry skin, mildly prominent forehead, and periorbital wrinkles. The younger one showed the same, but less severe, clinical features. After thorough examination and patient history evaluation, targeted next-generation sequencing analysis yielded the novel homozygous insertion variant c.322_323insCGGGC p.(Arg108ProfsTer7) in EDARADD. The mutation has not been reported to date in the literature.
    CONCLUSIONS: In this report, we present two siblings exhibiting classical HED symptoms and a novel insertion variant of the EDARADD gene, which leads to a frameshift introducing a stop codon. Both brothers inherited such mutation from their parents, who were heterozygous carriers of the same variant. The present study may shed light about the pathogenic mechanisms underlying HED, and expand the spectrum of EDARADD gene variants associated with this condition.

    进化生物学和群体遗传学的一个基本目标是了解选择如何影响新突变的命运。在这里,我们测试了零假设,即蛋白质编码区中的插入-缺失事件(indel)相对于二级结构随机发生。我们在小鼠中鉴定了11,444个序列比对的indel,rat,人类,黑猩猩,和狗的基因组,然后量化它们与四种不同类型的二级结构-α螺旋的重叠,β链,蛋白质弯曲,和蛋白质转变-通过AlphaFold2的深度学习方法预测。Indels与二级结构的重叠程度达到预期的54%,特别是在β链上代表性不足,往往形成内部,蛋白质的稳定区域。相比之下,在没有任何预测的二级结构的区域中,indel富集了155%。与灵长类动物谱系相比,啮齿动物谱系中的这些偏斜更强,与种群遗传理论一致,预测自然选择在有效种群规模较大的物种中效率更高。非同义替换在蛋白质二级结构区域中也不太常见,虽然没有像indel那样严重减少。在对数千个人类基因组的互补分析中,我们表明,重叠二级结构的indel分离频率明显低于二级结构外的indel。一起来看,我们的研究表明,如果插入缺失与二级结构重叠,大概是因为它们破坏了蛋白质的三级结构和功能。
    A fundamental goal in evolutionary biology and population genetics is to understand how selection shapes the fate of new mutations. Here, we test the null hypothesis that insertion-deletion (indel) events in protein-coding regions occur randomly with respect to secondary structures. We identified indels across 11,444 sequence alignments in mouse, rat, human, chimp, and dog genomes and then quantified their overlap with four different types of secondary structure-alpha helices, beta strands, protein bends, and protein turns-predicted by deep-learning methods of AlphaFold2. Indels overlapped secondary structures 54% as much as expected and were especially underrepresented over beta strands, which tend to form internal, stable regions of proteins. In contrast, indels were enriched by 155% over regions without any predicted secondary structures. These skews were stronger in the rodent lineages compared to the primate lineages, consistent with population genetic theory predicting that natural selection will be more efficient in species with larger effective population sizes. Nonsynonymous substitutions were also less common in regions of protein secondary structure, although not as strongly reduced as in indels. In a complementary analysis of thousands of human genomes, we showed that indels overlapping secondary structure segregated at significantly lower frequency than indels outside of secondary structure. Taken together, our study shows that indels are selected against if they overlap secondary structure, presumably because they disrupt the tertiary structure and function of a protein.

    三角肌是三节肌,中间,和后部组件。虽然三角肌起源和插入的解剖变异的存在的临床相关性仍然存在争议,三角肌的结构比最初认为的要复杂。本研究旨在通过定性和定量表征三角肌前部的插入和位置来评估三角肌插入的总体解剖结构,中间,和后部组件。这些信息对外科医生很有价值,因为它提高了人们对手术过程中可能遇到的潜在变异的认识。促进神经血管接近的正念,并减少相邻肌纤维之间混淆的可能性。
    八个非配对,该研究获得了新鲜冷冻的锁骨至指尖尸体肩膀(左侧6,2右)。尸体的平均年龄为79.5岁(范围:64-92)。对所有标本进行了标准的三角区方法。划分前部的飞机,中间,识别并标记后三角肌。一旦完全暴露,数字卡尺用于记录三角肌插入的大小。对标本进行定性评估,以表征它们所展示的插入方式。
    三角肌插入的平均长度为39.45±9.33mm(n=8)。八个肩部中的六个显示了文献中先前描述的插入样式。剩余的两个肩部突出了先前未描述的插入图案。
    当前的研究证明了一种先前尚未表征的三角肌的新型插入模式。这种“步进”插入模式表明,前部,中间,后肌腱插入上内侧,直接在,和三角肌结节的下外侧,在我们的尸体标本的2/8中发现。
    UNASSIGNED: The deltoid is a trisegmented muscle with anterior, middle, and posterior components. While the clinical relevance of the presence of anatomic variations of the deltoid origin and insertion continues to be debated, the architecture of the deltoid muscle is more complex than initially believed. This study aimed to evaluate the gross anatomy of the deltoid muscle insertion by qualitatively and quantitatively characterizing the insertion and location of the deltoid muscle\'s anterior, middle, and posterior components. This information is valuable to surgeons as it raises awareness of potential variants that could be encountered during surgery, promotes mindfulness of neurovascular proximities, and reduces the likelihood of confusion between adjacent muscle fibers.
    UNASSIGNED: Eight nonpaired, fresh-frozen clavicle-to-fingertip cadaveric shoulders were acquired for the study (6 left, 2 right). The average age of the cadavers was 79.5 years (range: 64-92). The standard deltopectoral approach was carried out on all specimens. The planes dividing the anterior, middle, and posterior deltoid were identified and marked. Once complete exposure had been achieved, digital calipers were used to record the size of the deltoid insertion. The specimens were qualitatively assessed to characterize the style of insertion they demonstrated.
    UNASSIGNED: The average length of the deltoid insertion was 39.45 ± 9.33 mm (n = 8). Six of the eight shoulders demonstrated an insertion style previously characterized in the literature. The remaining two shoulders highlighted an insertion pattern not previously described.
    UNASSIGNED: The current study demonstrates a novel insertion pattern for the deltoid muscle that has not been previously characterized. This \"step-off\" insertion pattern shows that the anterior, middle, and posterior tendons are inserted superior-medial, directly on, and inferior-lateral to the deltoid tuberosity and was found in 2/8 of our cadaveric specimens.

    本研究旨在评估义齿佩戴对全口义齿插入前后口腔真菌分离株发生的影响。选择了50名完全无牙的患者。在从pal粘膜表面制造全口义齿之前和全口义齿制造之后(插入义齿后1和7天),在口腔内收集拭子样品。Further,这些样品被接种和孵育。结果显示,在48例患者中,在义齿插入之前没有发现真菌的分离。在两个科目中,结果是假阳性(来自环境的污染),在六个病人中,增长有所增加,但是没有看到生长的显着增加(仅在插入义齿后真菌的轻度生长)。这项研究的主要发现之一是,口腔中真菌分离株(义齿插入前后)的总体发生率并不显着。
    The present study aimed to evaluate the effect of denture wearing on the occurrence of fungal isolates in the oral cavity before and after complete denture insertion. Fifty completely edentulous patients were selected. Swab samples were collected intraorally before the fabrication of complete dentures from the palatal mucosal surface and after complete denture fabrication (1 and 7 days after denture insertion). Further, these samples were inoculated and incubated. Results showed that in 48 patients, no isolate of fungus before denture insertion was found. In two subjects, results were false positive (contamination from the environment), and in six patients, there was an increase in growth, but not much significant increase of growth was seen (mild growth of fungus only after denture insertion). One of the major findings of this study was that the overall occurrence of fungal isolates (before and after denture insertion) in the oral cavity was not significant.

    前交叉韧带(ACL)中股骨骨隧道的理想位置存在争议。ACL纤维的功能重要性根据其连接到股骨的位置而变化。功能上重要的纤维会对骨骼造成高机械应力,沃尔夫定律预测,在高机械应力部位,骨矿物质密度会增加。
    这项研究的目的是使用计算机断层扫描成像来确定髁间外侧壁中骨密度的分布模式。据推测,外侧髁间壁的高密度区域(HDA)将反映ACL的功能插入,如先前的解剖学研究中所述。
    描述性流行病学研究。
    回顾性收集了39个无ACL损伤的膝关节数据。髁间侧壁的HDA被定义为包含放射密度值的顶部10%的区域。HDA的形状近似为椭圆形,并采用象限法确定椭圆的中心。研究了椭圆的短轴与长轴之比与背景特征之间的关联。
    根据象限方法,HDA椭圆的中心在深浅方向为33.6%,在高低方向为23.4%。椭圆的中心与ACL足迹的解剖中心相当,如先前报道。椭圆的短轴与长轴的比率为0.58(95%CI,0.54-0.62)。HDA椭圆短轴与长轴之比与胫骨后斜率呈显著负相关(r=-0.38,P=.02)。
    发现HDA椭圆的中心与ACL足迹的解剖中心相似。考虑到骨骼中的机械应力响应,外侧髁间壁的HDA有可能代表ACL插入,特别是功能插入。
    UNASSIGNED: The ideal position of the femoral bone tunnel in the anterior cruciate ligament (ACL) is controversial. The functional importance of the ACL fiber varies depending on where it is attached to the femur. Functionally important fibers can cause high mechanical stress on the bone, and the Wolff law predicts that bone mineral density will increase at high mechanical stress sites.
    UNASSIGNED: The purpose of this study was to use computed tomography imaging to determine the distribution pattern of bone density in the lateral intercondylar wall. It was hypothesized that the high-density area (HDA) of the lateral intercondylar wall would reflect the functional insertion of the ACL as reported in previous anatomic studies.
    UNASSIGNED: Descriptive epidemiology study.
    UNASSIGNED: Data from 39 knees without ACL injuries were retrospectively collected. The HDA of the lateral intercondylar wall was defined as the region containing the top 10% of the radiodensity values. The shape of the HDA was approximated as an ellipse, and the quadrant method was used to determine the center of the ellipse. The association between the ratio of the minor axis to the major axis of the ellipse and background characteristics was investigated.
    UNASSIGNED: According to the quadrant method, the center of the HDA ellipse was 33.6% in the deep-shallow direction and 23.4% in the high-low direction. The center of the ellipse was comparable to the anatomic center of the ACL footprint, as previously reported. The ratio of the minor axis to the major axis of the ellipse was 0.58 (95% CI, 0.54-0.62). There was a significant negative correlation between the ratio of the minor axis to the major axis of the HDA ellipse and the posterior tibial slope (r = -0.38, P = .02).
    UNASSIGNED: The center of the HDA ellipse was found to be similar to the anatomic center of the ACL footprint. Considering the mechanical stress responses in bone, the HDA of the lateral intercondylar wall has the potential to represent the ACL insertion, especially functional insertion.
