<p>，/PRNewswire/ -- 一项比较男性和女性膝关节损伤的最大 MRI 研究之一揭示了基于性别和年龄的损伤模式的惊人差异。这些发现可以用于改善风险评估和制定早期干预策略，将在今天的北美放射学会（RSNA）年会上进行展示。</p>
<p>“近年来，我们对男性和女性膝关节损伤之间的差异越来越感兴趣，” 研究共同作者、约翰霍普金斯医学院放射学助理教授 Jenifer Pitman 博士说。“过去大多数研究集中在男性身上，但随着我们将关注点扩大到女性，我们发现她们的风险特征不同，容易受到不同类型的损伤。”</p>
<p>该研究包括 2019 年至 2024 年在四个与约翰霍普金斯医院相关的门诊放射学设施中进行的 13,549 例连续常规膝关节 MRI 检查。患者以膝关节疼痛为主要诉求。研究人员从放射学报告中提取了以下特征：内侧和外侧半月板的撕裂或损伤、前交叉韧带（ACL）、后交叉韧带、内侧副韧带（MCL）、外侧副韧带复合体，以及伸展机制或髌股脱位。</p>
<p>ACL 是膝关节中的主要韧带，连接大腿骨和小腿骨，提供稳定性，特别是在扭转、跳跃、突然停止或改变方向时。ACL 损伤在运动中很常见，可能导致膝关节疼痛、肿胀和不稳定。半月板是膝关节内侧（内侧）和外侧（外侧）C 形的软骨片，起到减震器的作用，缓冲关节并提供稳定性。半月板的撕裂可能发生在扭转损伤或随着时间的推移逐渐磨损。</p>
<p>MRI 报告的分析显示，特定损伤在男性中观察到的频率高于女性，包括单独的 ACL 撕裂、伴有内侧半月板撕裂的 ACL 撕裂或伴有外侧半月板撕裂的 ACL 撕裂。</p>
<p>“我们在 20 至 40 岁年龄组中看到男性的 ACL 撕裂更多，这与文献中报道的情况相反，” 第一作者、约翰霍普金斯大学博士后研究员 Ali Ghasemi 博士说。“之前针对运动相关损伤的研究表明，年轻女性运动员的 ACL 撕裂发生率更高，风险更大。然而，我们的结果显示，男性患者在所有年龄组中 ACL 损伤的发生率显著更高。”</p>
<p>Pitman 博士推测，他们的研究与之前研究之间的差异可能是由于将关注点扩大到运动相关膝关节损伤以外。约翰霍普金斯的研究人员研究了所有有膝关节疼痛的患者，无论年龄或损伤原因。</p>
<p>男性的损伤总数更多。</p>
<p>研究人员还发现，半月板和 MCL 撕裂在 40 岁以下的男性和年长女性中更为常见。</p>
<p>“在年轻患者中，半月板和 MCL 撕裂更常见于男性，而在年长患者中，女性的这种类型的撕裂比男性更多，这出乎意料，” Ghasemi 博士说。</p>
<p>这些发现表明，年长女性更容易受到导致关节退化的损伤。</p>
<p>“男性和女性都应该采取预防措施，以避免高冲击损伤，特别是在运动或身体活动中，女性，尤其是 40 岁以上的女性，应关注关节健康，并考虑加入专门的力量训练，以帮助保护她们的膝关节，随着年龄的增长，” Pitman 博士说。</p>
<p>识别损伤模式可能帮助放射科医生和临床医生量身定制影像协议、风险评估和早期干预策略，以优化患者结果。</p>
<p>“预先建立的观念认为 ACL 撕裂在年轻女性中更为常见，可能并不总是成立，” Pitman 博士说。“放射科医生还可以预期在年长女性中看到更频繁的半月板病理和关节炎。”</p>
<p>研究人员正在继续调查按性别划分的膝关节损伤模式，分析人口统计信息和患者历史，以更好地理解损伤模式的趋势。</p>
<p>Pitman 博士表示，运动员应考虑与健康专业人士合作，以在膝关节周围建立平衡的力量。她建议有膝关节疼痛的个人，尤其是年长患者，去看医生。</p>
<p>“如果你有膝关节疼痛，不要轻易忽视或归因于年龄问题，” 她说。“我们看到 40 岁及以上女性的半月板撕裂发生率更高。”</p>

<p>在 RSNA 会议上发布的一项研究揭示了膝关节损伤模式的性别差异，男性的前交叉韧带（ACL）撕裂率较高，这与之前的研究相反。研究表明，年长女性更容易发生半月板和内侧副韧带（MCL）撕裂，表明关节退化。研究结果旨在改善风险评估和干预策略，呼吁两性在进行体育活动时采取预防措施</p>

<p>, /PRNewswire/ -- One of the largest MRI-based studies comparing knee injuries between men and women reveals surprising differences in injury patterns based on gender and age. The findings, which can be used to improve risk assessment and develop early intervention strategies, will be presented today at the annual meeting of the Radiological Society of North America (RSNA).</p>

</div><p>&#34;In recent years, we've grown more interested in the differences in knee injuries between men and women,&#34; said study co-author Jenifer Pitman, M.D., assistant professor of radiology at Johns Hopkins Medical Institute in Baltimore, Maryland. &#34;The majority of past research has focused on men, but as we expand our focus to include women, the more we see that they have different risk profiles and are prone to different injuries.&#34;</p>

</div><p>The study included 13,549 consecutive routine knee MRI exams performed between 2019 and 2024 at four outpatient radiology facilities affiliated with Johns Hopkins Hospital. The patients reported knee pain as their chief complaint. The researchers extracted the following features from radiology reports: tears in or injuries to the medial and lateral menisci, anterior cruciate ligament (ACL), posterior cruciate ligament, medial collateral ligament (MCL), lateral collateral ligament complex, and extensor mechanism or patellofemoral dislocation.</p>

</div><p>The ACL is a major ligament in the knee that connects the thigh bone to the shin and provides stability, especially during twisting, jumping, sudden stops or changes in direction. ACL injuries are common in sports and can cause pain, swelling and instability in the knee. The menisci are C-shaped pieces of cartilage on the inner (medial) and outer (lateral) side of the knee that act like shock absorbers, cushioning the joint and providing stability. Tears in the menisci can happen with twisting injuries or gradual wear and tear over time.</p>

</div><p>Analysis of the MRI reports revealed that specific injuries were observed more often in men compared to women, including ACL tears alone, ACL tear with medial meniscal tear or ACL tear with lateral meniscal tear.</p>
<div class="lb-trans"><p>MRI 报告的分析显示，特定损伤在男性中观察到的频率高于女性，包括单独的 ACL 撕裂、伴有内侧半月板撕裂的 ACL 撕裂或伴有外侧半月板撕裂的 ACL 撕裂。</p>
</div><p>&#34;We saw more ACL tears in men especially in the 20- to 40-year-old age group, which is contrary to what's been reported in the literature,&#34; said first author Ali Ghasemi, M.D., postdoctoral research fellow at Johns Hopkins. &#34;Prior studies focused on sports-related injuries have shown that young women athletes have increased rates of and a greater risk for ACL tears. However, our results show a significantly higher prevalence of ACL injuries in male patients across all age groups.&#34;</p>

</div><p>Dr. Pitman theorized the discrepancy between their research and previous studies may be due to broadening their focus beyond sports-related knee injuries. The Johns Hopkins researchers studied all patients with knee pain, regardless of age or cause of injury.</p>
<div class="lb-trans"><p>Pitman 博士推测，他们的研究与之前研究之间的差异可能是由于将关注点扩大到运动相关膝关节损伤以外。约翰霍普金斯的研究人员研究了所有有膝关节疼痛的患者，无论年龄或损伤原因。</p>
</div><p>Men had a greater number of injuries overall.</p>
<div class="lb-trans"><p>男性的损伤总数更多。</p>
</div><p>The researchers also found that meniscal and MCL tears occurred more frequently in men under 40 and among older women.</p>
<div class="lb-trans"><p>研究人员还发现，半月板和 MCL 撕裂在 40 岁以下的男性和年长女性中更为常见。</p>
</div><p>&#34;In younger patients, meniscal and MCL tears were more commonly seen in men, while in older patients, women had more of these types of tears than men, which was unexpected,&#34; Dr. Ghasemi said.</p>
<div class="lb-trans"><p>“在年轻患者中，半月板和 MCL 撕裂更常见于男性，而在年长患者中，女性的这种类型的撕裂比男性更多，这出乎意料，” Ghasemi 博士说。</p>
</div><p>The findings suggest that older women are more prone to injuries that lead to joint degeneration over time.</p>
<div class="lb-trans"><p>这些发现表明，年长女性更容易受到导致关节退化的损伤。</p>
</div><p>&#34;Both men and women should take precautions to avoid high-impact injuries, especially during sports or physical activity and women, especially over 40, should pay attention to joint health and consider incorporating dedicated strength training to help protect their knees as they age,&#34; Dr. Pitman said.</p>
<div class="lb-trans"><p>“男性和女性都应该采取预防措施，以避免高冲击损伤，特别是在运动或身体活动中，女性，尤其是 40 岁以上的女性，应关注关节健康，并考虑加入专门的力量训练，以帮助保护她们的膝关节，随着年龄的增长，” Pitman 博士说。</p>
</div><p>Recognizing the injury patterns may help radiologists and clinicians tailor imaging protocols, risk assessments and early intervention strategies to optimize patient outcomes.</p>
<div class="lb-trans"><p>识别损伤模式可能帮助放射科医生和临床医生量身定制影像协议、风险评估和早期干预策略，以优化患者结果。</p>
</div><p>&#34;The pre-established notion that ACL tears are more common in younger women may not be the case 100% of the time,&#34; Dr. Pitman said. &#34;Radiologists can also expect to see more frequent meniscal pathology and arthritis in older women.&#34;</p>
<div class="lb-trans"><p>“预先建立的观念认为 ACL 撕裂在年轻女性中更为常见，可能并不总是成立，” Pitman 博士说。“放射科医生还可以预期在年长女性中看到更频繁的半月板病理和关节炎。”</p>
</div><p>The researchers are continuing their investigation into knee injury patterns by gender, analyzing demographic information and patient history to better understand trends in injury patterns.</p>
<div class="lb-trans"><p>研究人员正在继续调查按性别划分的膝关节损伤模式，分析人口统计信息和患者历史，以更好地理解损伤模式的趋势。</p>
</div><p>Dr. Pitman said that athletes should consider working with a health professional to build balanced strength around the knee. She advises individuals—especially older patients—with knee pain to see their physician.</p>
<div class="lb-trans"><p>Pitman 博士表示，运动员应考虑与健康专业人士合作，以在膝关节周围建立平衡的力量。她建议有膝关节疼痛的个人，尤其是年长患者，去看医生。</p>
</div><p>&#34;If you're having knee pain, don't just brush it off or attribute it to old age,&#34; she said. &#34;We've seen higher rates of meniscal tears, in particular, in women 40 years and older.&#34;</p>
