Forces Which May Cause Injury

Ligament Injury

Anterior tibial translation and internal torque loads can injure the ACL or stretch out a graft.

Ligament Injury

Increased medial joint opening during lateral blows, which occur in contact sports, can injure both the MCL and ACL.

Ligament Injury

Hyperextension of the knee if knee is straightened more than 10º

beyond the

fully extended position

Ligament Injury

Small knee flexion angles at initial contact during landing tasks may contribute to “non-

contact”

ACL injuries.

Active Braces

DJO ACL/PCL LIGAMENT BRACESACTIVE BRACES

! 4 POINT DESIGN !

Actively addresses instability at all times

Active vs. Passive Braces

The tibial control component encompasses the tibia and parallels the tibial crest to help inhibit anterior and pivotal tibial excursion caused by ACL laxity. The non-elastic upper cruciate

strap provides an opposing force on the femur to help stabilize the knee.

A six-point system helps provide excellent medial and lateral support. The rigid graphite frame's lateral arms, condylar

support at the joint and non-elastic Velcro straps help inhibit medial and lateral instability. Blue arrows indicate support opposing valgus forces; white arrows indicate support opposing varus

forces.

Conclusion

Extra ACL Protection

FourcePoint

Hinge

FourcePoint

Why is added ACL protection needed?

•

>75% of all ACL ruptures are non-contact•

Women are up to 10X more likely to suffer a non-contact ACL injury than men

•

Non-contact ACL injuries frequently occur during stop- jump activities

Forward Vertical Backward

FourcePoint

What puts ACL at risk? •

Joint angles less than 600

(Beynnon; Markolf)

Objective•

Determine the effects of a specially designed knee brace on the lower extremity kinematics & kinetics of athletes in a stop-jump task in which non-contact ACL injuries frequently occur

FourcePoint

Study Design•

12 male & 12 female recreational athletes 18-28 years old

•

3-D coordinates of reflective markers placed on selected critical body landmarks

•

5 trials with & without the new brace for each subject

Does 5o

flexion angle increase matter?

•

The anterior shear force applied on the tibia will be reduced by 9% for females & 13%

for males (Nuley

et al.,

2002)•

The decrease in anterior shear force on the tibia will substantially reduce the load on the ACL
