To illustrate the variety of posterior cruciate ligament (PCL) injuries and assess the type and frequency of associated knee injuries.
In a retrospective review of 1,950 magnetic resonance (MR) examinations of the knee, 47 patients with MR imaging findings of PCL injury were identified. In 24 patients, the findings on MR images were correlated with athroscopic findings (n = 14) or findings at physical examination (n = 10). Patterns of associated injuries were described and tabulated.
Twenty-one patients (45%) had complete PCL tears; 22 patients (47%), partial tears; and four patients (9%), bone avulsion. Associated injuries were seen in 34 patients (72%). Patterns of injuries differed from those seen in anterior cruciate ligament injury and correlated with the mechanism of trauma.
MR imaging proved accurate in assessment of the PCL in patients with clinical correlation and demonstrated patterns of associated injury that may affect management strategy.
阐述后交叉韧带（PCL）损伤的多样性，并评估相关膝关节损伤的类型和频率。
回顾性分析1950例膝关节磁共振（MR）检查，确定47例有PCL损伤MR成像表现的患者。其中24例患者的MR图像表现与关节镜检查结果（n = 14）或体格检查结果（n = 10）相关。描述并列表显示相关损伤的模式。
21例患者（45%）为PCL完全撕裂；22例患者（47%）为部分撕裂；4例患者（9%）为骨撕脱。34例患者（72%）存在相关损伤。损伤模式与前交叉韧带损伤不同，且与创伤机制相关。
MR成像在临床相关患者的PCL评估中被证明是准确的，并显示出可能影响治疗策略的相关损伤模式。
