Is the Bionic Knee Brace for me?

The Bionic Knee Brace is ideal for athletes looking for MCL and LCL support. It is not an ACL brace. It can also help with hyperextended knee injuries and meniscus support and works well for sports. Still not sure? Try our Brace Advisor for personalized product recommendations to meet your needs!

The hinges work by absorbing energy and impact as you move so that you can move freely and without restriction. Use the Bionic to help you continue your activities as you are recovering from injury and stay in the game.

Product Questions

I'm a polio patient (1952) have a hyper extended knee due to loss of muscle mass back of lower leg. I need a stop to allow me to put weight on my leg and not have it lock in a hyper extended condition. Brace migration is an issue with loss of muscle condition. I feel I need a moderate to high support brace. Any help on recommending a brace.

The DonJoy Performance Bionic Knee Brace has a hard stop built into it to prevent hyperextension, and support knee instability with lateral and medial protection.

Let me know whether I can wear the Bionic Knee Brace under the pants?
Thanks. Peter
Question by: Peter on Aug 17, 2016, 8:10 AM
The DonJoy Performance Bionic Knee Brace is a low profile brace but it does have protective hinges. You can wear the brace under pants as long as the pants have enough leg room to accommodate the brace.

should measurements be taken while in a relaxed seated position on a table or with knee flexed slightly? measurements are different and fluctuates between ordering a large or XL brace
Question by: jeff on Aug 20, 2016, 6:50 AM
For measurements, stand with your legs shoulder-width apart, legs slightly bent and leg muscles contracted. Measure up six inches from the center of your knee with a tape measure. Measure the circumference of your thigh at the 6-inch mark. Then measure down six inches from the center of your knee with a tape measure. Then measure the circumference of your calf at the 6-inch mark.

I wear the Don Joy armor knee brace for my torn ACL. And it slips and slides and is very un comfortable. Would this be good to wear for more comfort?
Question by: Hunter waggener on Mar 20, 2016, 3:08 PM
The Bionic Knee does not provide ACL specific support. For ACL support we recommend the Bionic Fullstop Knee Brace https://www.donjoystore.com/bionic-fullstop-knee-brace

I have very little cartilage left in my knee. I am using your competitors ultra knee support w/bilateral hinges. They work well but their construction is shoddy. Would this be a good replacement?
Question by: PJ on Aug 30, 2015, 3:28 PM
Yes this brace is made with the DJO quality standard, we also have a six month warranty on all of our soft good products.
