Learn how to size and fit your Donjoy knee brace
Monday, 10 April 2017
Donjoy Armor knee braces are the industry standard in providing protection and support to the knees during physical activity, giving athletes the confidence to push themselves without the fear of injury. These knee braces can boost both support and safety for the user, but these benefits are jeopardised if the proper care and attention are not taken in the sizing process. A properly sized knee brace will support and protect the areas where it's needed most, but with improper sizing the brace can slip and lose many of its key attributes.
Sizing Your Knee Brace
The sizing of Donjoy Armor braces is quick and easy, with three key measurements to be made in order to ensure the perfect fit. The three necessary measurements are described and shown below.
These sizing and application instructions apply to the following Donjoy Knee Braces, all available from Think Sport with free UK delivery on all orders over £40.
Once you've properly measured your leg at the thigh, knee and calf, and have ordered the right size for you, you're ready to try your brace on and feel the support for yourself. Before you begin, we've compiled a few key tips to help your application go as smoothly as possible:
Step-By-Step Knee Brace Application Instructions
Now that you're prepared for proper application of your knee brace, we've prepared a step-by-step guide to ensure the perfect application, every time.
Step 1: Initial Preparation
A. To start off the application, sit on the edge of your firm surface in a stable position.
B. Ensure that your knee is slightly bent (45°), and your foot is placed flat on the floor (Figure 1).
Step 2: Brace and Hinge Placement
A. Now that you're seated in the proper position, undo the straps and step through the brace (Figure 2A).
B. Holding the brace by the hinges, centre the hinges 1 inch above the top of your knee cap.
C. Then, push the hinges slightly back behind the midline of the knee (Figure 2B).
Step 3: Anti-Migration Band Placement
A. Secure the anti-migration calf band around the leg with a snug fit. Make sure this band is in full contact with the leg and does not wrap around the outside of the brace (Figure 3). Please note that the anti-migration band is not designed to be threaded through any plastic buckle and should wrap directly around your leg.
B. Please note that the anti-migration band is connected to both Strap #4 and Strap #5. Neither of these straps should be fastened until later on in the fitting process.
Step 4: Secure Straps #1 and #2
A. Secure the strap #1 (which is the lowest strap on the calf until it has a snug fit (Figure 4A).
B. Secure the top thigh strap #2, but not too tightly, as that can cause the brace to slip down your leg (Figure 4B).
C. Again, following this step, push the hinges slightly back behind the midline of your knee.
Step 5: Secure Straps #3 and #4
A. Secure the lower thigh strap #3 until you feel a snug fit (Figure 5A).
B. Secure upper front calf strap #4 until it is very snug. (Figure 5B). Strap #4 can be found at the front of the anti-migration band and should be threaded through the loops on the band. This step is especially critical for patients with ACL injuries.
Step 6: Securing Strap #5
A. Secure the back calf strap #5, which again is connected to the anti-migration band, until is has a comfortable fit (Figure 6).
B. After the initial fitted of this strap, you do not need to undo it. It will work to keep the anti-migration band in place.
Step 7: Check your Fit and Re-Tighten
A. At this point, your brace should fit snugly to your leg. OA patients should feel a slight push on one side of the knee. If you have done this correctly, your brace should now be fully fitted (Figure 7).
Additional Troubleshooting Tips
If you've followed these instructions and still find that your knee brace doesn't fit as well as it should, here are some extra tips to help you out.
1: Ensure Proper Hinge Placement
A. In a perfectly-fit knee brace, the hinges will be at the midline of your knee. The pads will be making full contact with your leg.
B. If the hinges of your knee brace are too far forward, you should loosen all the straps to allow for adjustment. Then, you can push the hinges back while raising them slightly up. After you've done this, retighten all the straps and re-evaluate your fit.
2: Ensure Proper Alignment
A. On a well-fit knee brace, the hinges should be slightly higher than your knee cap. The pads will be making full contact with your leg.
B. If the brace is too low down your leg, loosen all the straps. Then, raise the hinges up your leg, re-tighten the straps and re-evaluate your fit.
3: Ensure Proper Fit
A. If no mistakes have occurred during the sizing process and your knee brace fits correctly, there will be no major gapping between the brace and your leg. The pads will be making full contact with your leg.
B. If the brace you have selected is too large, you can add extra condyle pads to improve your fit. Alternately, you can call us at Think Sport to discuss a replacement with a more appropriate size.
4: Try Again
Due to the highly technical design of Donjoy Armor braces, they require a more precise fit in order to ensure that you are getting the optimal level of support. This naturally means that the application of the brace may take some getting used to before you can find the perfect fit. If you follow this guide and find that the brace does not fit well, it doesn't necessarily mean that you have purchased the incorrect size. Try fitting your brace another two or three times to ensure that you have a good grasp of the application process.
