|DonJoy® Armor Action with FourcePoint Short Knee Braces
We are very impressed with this ACL brace for your patients. the Armor with FourcePoint® by DonJoy® is the logical combination of the strongest, off-the-shelf functional knee brace on the market with the patented technology of the low profile FourcePoint® Hinge. It lets your patient perform at the highest level after knee injury. Great for return to sport in the time you determine safe after ACL reconstruction. It is designed for active people seeking ligament protection, better fit, and superb comfort.
The New Armor FourcePoint® is ideal for patients returning to sports-specific activity after:
ACL reconstruction for an ACL deficient knee
Prophylaxis in all but extreme and contact sports
Hyperextension injury (not those with isolated PCL and posterolateral corner injury)
The new low profile patented FourcePoint® hinges are designed to react during leg extension and offer an increasing resistance in the last 35 degrees of extension, in order to reduce extension shock and increase posterior tibial loads. This is what Donjoy call "Dynamic ACl Protection". The hinge has three adjustment settings to vary the amount of resistance to meet the specification of the doctor's protocols and the patient's comfort.
Information on Ordering
Select the size for your patient by measuring the circumference of the patients thigh 15cm above the mid point of the patella. Ask your patient to adopt the schuss position with the knees bent to 20 degrees. If your patient has quads wasting you expect to improve over the next 3 months then measure from the normal limb.
Don't forget to specify side (ACL=Anterior Cruciate Ligament injury or reconstruction).

Knee Bracing after ACL Reconstruction
John Hardy recommends the Armor with FourcePoint® as an off the shelf and cost effective brace for patients returning to skiing after ACL reconstruction and 6 months of rehabilitation.
John is a Consultant Knee Surgeon in London and Bristol in the UK.
John told OrthopaedicsandTrauma.com "Although the elegant study by Malcolm Pope from Vermont was on the predecessor to the Donjoy Armor this study demonstrated there was some protective value of using a knee brace to protect an ACL reconstruction in an athlete keen to return to sport".
