Purpose

To analyse 1000 consecutive patients, treated with isolated or combined posterior cruciate ligament (PCL) reconstruction in a single centre according to the epidemiological factors and differences in injury patterns depending on the activity during trauma.

Methods

Between 2004 and 2019, one thousand isolated and combined PCL reconstructions were performed. The medical charts and surgical reports of all patients were analysed regarding epidemiological factors. The PCL lesions were divided into isolated and combined lesions with at least one additional ligamentous injury. The influence of activity during accident and additional injury on the presence of isolated or combined lesions and injury patterns was calculated.

Results

In 388 patients (38.8%), sporting activity was the main activity in PCL lesions, followed by traffic accidents in 350 patients (35.0%). Combined injuries were present in 227 patients (58.5%) with sports injuries and 251 patients (71.7%) with traffic accidents. Only during handball, an isolated PCL lesion (69.1%) was more common than a combined lesion. Highest rate of combined lesions was present in car accidents (91.7%). In all activities except skiing and biking, the most common additional peripheral injury was a tear of the posterolateral corner. In skiing and biking accidents, the most common additional peripheral lesion was a lesion of the medial collateral ligament. In patients with PCL lesion and additional fracture of the same lower extremity, a combined lesion was more common than an isolated lesion (p = 0.001).

Conclusion

Combined PCL lesions are more common than isolated lesions, even in sports injuries (except handball). Incidence and injury pattern vary depending on activity during trauma. Main additional peripheral lesion is a lesion of the posterolateral corner, except biking and skiing accidents where a medial lesion is more common.

后十字韧带病变主要表现为合并病变，即使在运动损伤中也是如此。

目的

为了分析流行病学因素以及根据创伤期间活动的损伤模式的不同，在单个中心用隔离或联合后十字韧带（PCL）重建术治疗的1000例连续患者。

方法

在2004年至2019年之间，进行了1000例隔离和合并的PCL重建。对所有患者的病历和手术报告进行了流行病学因素分析。将PCL病变分为孤立病变和合并病变，并伴有至少一种额外的韧带损伤。计算了事故和额外伤害期间活动对孤立或合并病变和伤害模式的影响。

结果

在388例患者中（38.8％），体育活动是PCL病变的主要活动，其次是350例交通事故（35.0％）。发生运动伤害的227例患者（58.5％）和发生交通事故的251例患者（71.7％）存在合并伤害。仅在手球期间，孤立的PCL病变（69.1％）比合并病变更常见。车祸中合并病变的发生率最高（91.7％）。在除滑雪和骑自行车之外的所有活动中，最常见的附加外围伤害是后外侧角撕裂。在滑雪和骑自行车事故中，最常见的附加周围病变是内侧副韧带病变。在PCL病变并伴有下肢相同的骨折的患者中，合并病变比单纯病变更常见（p = 0.001）。

结论

合并的PCL病变比孤立的病变更常见，即使在运动损伤（手球除外）中也是如此。发病率和损伤方式取决于创伤期间的活动。主要的附加周围性病变是后外侧角病变，除了自行车和滑雪事故，其中内侧病变更为常见。
