Introduction


Armor by DonJoy® is the strongest, off-the-shelf functional knee brace on the market and is designed for active people seeking ligament protection, excellent fit, and superb comfort.

Indications


The Armor is ideal for patients returning to sports-specific activity after:

• Prophylaxis in all but extreme sports
• MCL injuries
• LCL injuries
• Hyperextension injury (not those with isolated PCL and posterolateral corner injury)

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 and indication ACL=Anterior Cruciate Ligament injury or reconstruction
PCL=Posterior Cruciate Ligament injury or reconstruction
CI=Combined Ligament injury or reconstruction

Knee Brace Fitting


OrthopaedicsAndTrauma.com asked Claire Callaghan for her advice on brace fitting of the Armour and similar patented four point loading braces.

Claire Callaghan is a professional physiotherapist in Bristol at Sports Medicine Clinic, University of Bristol. Claire advises patients and athletes in rehabilitation on the management of their Donjoy braces.

Claire told OrthopaedicsandTrauma.com "The advantage of the four point brace is that the brace does not impinge on the subcutaneous border of your patient's shin. Compliance is therefore good and the brace does its job at protecting the ACL in the few degrees of flexion where help is most needed". She said "If you show your patient how to put their leg through the brace but bring the hinges posterior to the knee before bringing the hinges above the knee, as in the rolling video clip, then fitting is rapid, comfortable and simple. This tip is not in the removable instruction sheet taped to the side of every brace so it is worth remembering this tip when you bring the patient back for fitting the brace they have ordered in your clinic".
