To determine the epidemiology by player position, examination, imaging findings, and associated injuries of posterior cruciate ligament (PCL) injuries in players participating in the National Football League (NFL) Combine.
All PCL injuries identified at the NFL Combine (2009-2015) were reviewed. Data were obtained from the database organized by the NFL medical personnel for the compilation of the medical and physical performance examination results of NFL Draftees participating in the NFL Combine from 2009 to 2015. Inclusion criteria were any player with clinical findings or a previous surgery consistent with a PCL injury who participated in the NFL Combine.
Of the 2,285 players who participated in the NFL Combine between 2009 and 2015, 69 (3%) had evidence of a PCL injury, of which 11 players (15.9%) were managed surgically. On physical examination, 35 players (52%) had a grade II or III posterior drawer. Concomitant injuries were present frequently and included medial collateral ligament (MCL; 42%), anterior cruciate ligament (ACL; 11.6%), and chondral injuries (31.8%), especially in the lateral tibiofemoral compartment.
Three percent of the players at the NFL Combine presented with a PCL injury, with a significant amount being either running backs (14/69, 20.2%) or offensive linemen (14/69, 20.2%). Approximately half of the players with a PCL tear had a residual grade II or III posterior drawer after sustaining a PCL injury. Concomitant injuries were present frequently and included MCL (42%), ACL (11.6%), and chondral injuries (31.8%), especially in the lateral tibiofemoral compartment. For those players with clinical concern for PCL ligamentous laxity, there should be a complete comprehensive workup that includes plain and PCL stress view radiographs, and magnetic resonance imaging.

确定参加美国国家橄榄球联盟（NFL）联合试训的球员中，根据球员位置、检查、影像学表现和相关损伤，后交叉韧带（PCL）损伤的流行病学情况。
对 NFL 联合试训（2009-2015 年）中确定的所有 PCL 损伤进行了回顾。数据来自 NFL 医务人员组织的数据库，用于汇编 2009 年至 2015 年参加 NFL 联合试训的 NFL 选秀球员的医疗和身体表现检查结果。纳入标准为任何有临床发现或既往手术史符合 PCL 损伤并参加 NFL 联合试训的球员。
在 2009 年至 2015 年间参加 NFL 联合试训的 2285 名球员中，有 69 名（3%）有 PCL 损伤的证据，其中 11 名（15.9%）接受了手术治疗。体格检查时，有 35 名（52%）患者出现 II 级或 III 级后抽屉征。同时存在的损伤很常见，包括内侧副韧带（MCL；42%）、前交叉韧带（ACL；11.6%）和软骨损伤（31.8%），特别是在外侧胫骨股骨间室。
NFL 联合试训中有 3%的球员出现 PCL 损伤，其中相当一部分是跑卫（14/69，20.2%）或进攻线卫（14/69，20.2%）。大约一半的 PCL 撕裂患者在发生 PCL 损伤后仍有残余的 II 级或 III 级后抽屉征。同时存在的损伤很常见，包括 MCL（42%）、ACL（11.6%）和软骨损伤（31.8%），特别是在外侧胫骨股骨间室。对于那些有 PCL 韧带松弛临床疑虑的患者，应进行全面的综合检查，包括平片和 PCL 应力位 X 线片以及磁共振成像。
