Abstract No previous cases of anterior cruciate ligament (ACL) injuries sustained during wakeboarding have been reported. We report on a case involving an ACL injury sustained during wakeboarding.
A 27-year-old man sustained an injury while attempting a wakeboarding maneuver (a heel-side back roll, consisting of a jump and simultaneous roll toward the heel side). He failed to complete his roll before landing, striking the water with his right shoulder foremost, then plunging underwater. When his wakeboard struck the water, his left knee was sprained by the rotational force exerted by the board. The patient was diagnosed with an isolated ACL injury and underwent arthroscopic ACL reconstructive surgery.
The board used in wakeboarding is wider and subject to greater water resistance than that used in water skiing. The feet of the wakeboarder are firmly attached by binding boots to a board, laterally with respect to the direction of motion, impeding easy separation of the board from the feet in the event of a fall. Thus, wakeboarding conditions would appear to put wakeboarders at particular risk for ACL injuries. These conditions need be assessed from a medical perspective in order to devise ways to minimize the risk of such injuries.
