PURPOSE: To evaluate the incidence and risk factors for knee cartilage injury in elite college football players invited to attend the US National Football League (NFL) Scouting Combine over a 3-year period. METHODS: All players entering the NFL Scouting Combine (National Invitational Camp) from 2005 through 2007 were evaluated. "At-risk" knees underwent magnetic resonance imaging (MRI), and the results were evaluated for chondral injuries. RESULTS: During the 3-year period reviewed, a total of 980 players were available for analysis, and a total of 516 players' knee MRI scans were obtained (53% of all players at the Combine). The total number of full-thickness chondral injuries evident on MRI was 197 (20.1%) among all players, or 38.2% of the players who had an MRI scan. Of the players, 30 (3.06% of all players at the Combine, or 5.8% of the players who had an MRI scan) had isolated medial compartment full-thickness chondral injuries, 41 (4.2%, or 7.9%) had isolated lateral compartment full-thickness chondral injuries, 48 (4.9%, or 9.3%) had patellofemoral compartment full-thickness chondral damage, and 78 (7.96%, or 15.1%) had full-thickness chondral injuries in more than 1 compartment. CONCLUSIONS: The epidemiologic and risk assessment data presented in this study offer a cross-section of a young and elite athletic population who were "prescreened" at the NFL Combine over a 3-year period and judged to have at-risk knees. The total number of full-thickness chondral injuries evident on MRI was 197 (20.1%) among all players, or 38.2% of the players who had an MRI scan: 30 players (3.06%, or 5.8%) had an isolated medial compartment full-thickness chondral injury, 41 players (4.2%, or 7.9%) had an isolated lateral compartment full-thickness chondral injury, 48 players (4.9%, or 9.3%) had isolated patellofemoral compartment full-thickness chondral damage, and 78 players (7.96%, or 15.1%) had full-thickness chondral injuries in more than 1 compartment.
