Purpose: 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.
Methods: 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.
Results: 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.
Conclusions: 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.
Level of evidence: Level IV, case series.
