ACL and CI Options
Strapping is the main difference between the ACL and CI (combined instability) options for the DonJoy FullForce Ligament Knee Brace.
The ACL brace is for ACL-specific injuries and features a five-strap system that includes two posterior thigh straps, two anterior calf straps, and one lower posterior calf strap.
The CI brace (Combined Instability) is for ACL, PCL, and MCL ligament protection. The brace has the five-strap system plus an additional strap on the front of the thigh for enhanced stability.
4-Points-of-Leverage System
Enhances ligament stability through:
- Anchor on the anterior thigh
- Anchor on the posterior tibia
- Lower thigh strap pushes the femur forward
- Anterior tibia strap applies a constant load to prevent forward movement
Find the Perfect Fit
Measure the knee center, six inches above the knee center, and six inches below the knee center. Match the three measurements with the chart below to determine the most accurate brace size.
