The mean patient age was 33.3 \u00b1 11.2 years. Across all age groups, the most injured body parts were the ankle (36.0%), knee (32.7%), and lower leg (12.9%). The 20 to 39 age group experienced the greatest incidence of injuries from impact with the floor (national estimate [NE], 17,198; 37.4%). Additionally, this age group experienced the greatest incidence of dislocation (NE, 2379; 5.2%). The 40 to 59 age group had the highest proportion of injuries secondary to nonjumping noncontact movements (NE, 1781; 10.3%).
