To investigate differences in preoperative knee function (Knee Injury and Osteoarthritis Outcome Score, KOOS), the time period from injury to surgery, and associated injuries when comparing primary isolated posterior cruciate ligament (PCL) and primary anterior cruciate ligament (ACL) reconstructions.
Isolated primary ACL and PCL reconstructions registered in the Norwegian National Knee Ligament Registry from 2004 through 2010 were included (n = 71 primary PCLs and 9,649 primary ACLs). Linear regression analysis was used to evaluate the preoperative KOOS subscale values.
The preoperative KOOS in the PCL group (n = 71) and ACL group (n = 9,649) was significantly different for the subscales symptoms (mean difference, -8.4; 95% CI: -12.8 to -4.0), pain (mean difference, -15.9; 95% CI: -20.3 to -11.4), activities of daily living (mean difference, -12.9; 95% CI: -17.4 to -8.4), sport and recreation (mean difference, -15.9; 95% CI: -22.6 to -9.3), and quality of life (mean difference, -7.9; 95% CI: -12.4 to -3.5). The primary isolated PCL-reconstructed knees had a median time from injury to surgery of 21 months in comparison with 8 months for ACL injuries. The ACL-injured knees had more associated injuries (meniscus and full-thickness cartilage lesions) than the PCL-injured knees.
Surgically treated knees with an isolated rupture of the PCL exhibited worse knee function preoperatively compared with knees with an isolated ACL injury; in addition, the delay to surgery was longer. Meniscal lesions were found more frequently in ACL-injured knees.

比较原发性单纯后交叉韧带（PCL）和前交叉韧带（ACL）重建，研究术前膝关节功能（膝关节损伤和骨关节炎结果评分，KOOS）、从损伤到手术的时间间隔以及合并损伤的差异。
纳入 2004 年至 2010 年在挪威国家膝关节韧带登记处登记的单纯原发性 ACL 和 PCL 重建（n = 71 例原发性 PCL 和 9649 例原发性 ACL）。采用线性回归分析评估术前 KOOS 亚量表值。
PCL 组（n = 71）和 ACL 组（n = 9649）的术前 KOOS 在症状（平均差值，-8.4；95%CI：-12.8 至-4.0）、疼痛（平均差值，-15.9；95%CI：-20.3 至-11.4）、日常生活活动（平均差值，-12.9；95%CI：-17.4 至-8.4）、运动和娱乐（平均差值，-15.9；95%CI：-22.6 至-9.3）和生活质量（平均差值，-7.9；95%CI：-12.4 至-3.5）等亚量表方面存在显著差异。与 ACL 损伤相比，原发性单纯 PCL 重建膝关节的损伤至手术时间中位数为 21 个月，而 ACL 损伤为 8 个月。ACL 损伤的膝关节比 PCL 损伤的膝关节更常合并半月板和全层软骨损伤。
与 ACL 损伤相比，手术治疗的单纯 PCL 撕裂膝关节术前膝关节功能更差，手术时间延迟更长。ACL 损伤的膝关节更常发现半月板损伤。
