ACL Injuries – Facts & Figures

THE RISK OF ACL INJURY TO CONTRALATERAL KNEE IS 2-3 TIMES THAT OF THE RECONSTRUCTED KNEE

CONTRIBUTING FACTORS

• Decreased knee flexion angle
• Anterior tibial shear forces
• Combined valgus and knee internal rotation moments
• Combined valgus and knee external rotatinon

RE-INJURY

• The re-injury rate for the ACL reconstructed knee is 1.8%-10.4%
• Risk of ACL injury to the contralateral knee is double that of the reconstructed knee
• Only 1/3 of reconstructed athletes attempt to play competitive sports at their pre-injury level within one year following reconstruction
• Fear of re-injury prevented competitive college and high school football players from returning to play
• Re-injury rate is 6x greater compared to previously uninjured patients
• Re-injury rate is 5x higher in females compared to healthy females
• Females are 2x more likely to have an injury to the contralateral knee compared to the previously affected knee
• For every month that return to sports was delayed until 9 months post ACL-reconstruction, the rate of knee re-injury was reduced by 51%

USING A BRACE WITH FOURCEPOINT™ HINGE TECHNOLOGY IN CONJUNCTION WITH A 4-POINTS-OF-LEVERAGE™ FRAME DESIGN:

• Significantly increases knee flexion angle at peak posterior ground reaction force (PPGRF) by 9° vs. a standard braced knee and a non-braced knee
• Significantly decreases PPGRF during stop jump task landing and side-cutting activities
• No significant performance limitations were associated with the knee brace with FourcePoint hinge technology

ACL INJURY PREVENTION – PROPHYLACTIC BRACING CAN SIGNIFICANTLY REDUCE THE NUMBER OF KNEE LIGAMENT INJURIES.

CONTACT SPORTS – Reducing the risk of high impact knee ligament injuries

PROPHYLACTIC BRACE USE

Football

• May be effective in reducing the risk of incurring an MCL sprain in football, and generally provide 20-30% greater MCL resistance to a lateral blow
• Reduces injury rates among college football players, linemen, linebackers and tight ends when worn in both practices and games vs. unbraced players
• An internal analysis at a major Division I university football program, the number of days lost due to knee injury (and related associated healthcare costs) was reduced by 99% from year 1 to year 2 through the use of a custom fitted prophylactic knee brace in the 2nd year

Off-road Motorcycling

• Reduces ACL injury rates by 50% with a 7-fold decrease in MCL injury rates

Skiing

• Reduces ACL reinjury by 3-times compared to non-braced

NON-CONTACT – Reducing the risk of injury to the contralateral knee

WEARING NO BRACE OR A KNEE BRACE WITHOUT FOURCEPOINT™ HINGE TECHNOLOGY (RESULTS AT 6-12 MONTHS POST-OP)

• 30% deficit in joint mechanics
• Asymmetry of mechanics in both knees

A BRACE EQUIPPED WITH 4-POINTS-OF-LEVERAGE PLUS FOURCEPOINT IS A CLINICALLY-PROVEN COMBINATION TO PROTECT AND PREVENT INJURY TO THE ACL.
