Every time you take a step your knees are bearing 3x your bodyweight, and up to 5x if you’re walking down stairs or downhill!



The knee joint is the largest joint in the human body. Although the largest, it is the most vulnerable for injuries since it withstands an incredible amount of impact while in a flexed position. Alike the elbow joint, the knee is able to bend and straighten, but also rotate slightly from side to side.


Injuries to the knee can be very debilitating and painful. They can be caused by a quick accident or result from an ongoing issue, such as poor biomechanics or diseases like Osteoarthritis. Some of the most common knee injuries are caused by damage to the surrounding ligaments. The four ligaments of the knee that are prone to injury are the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Lateral Collateral Ligament (LCL) and Medial Collateral Ligament (MCL). Since these ligaments work together to stabilize the knee and prevent unwanted movement, injuries (such as tears) to these fibrous connective tissues can severely reduce the overall stability of the knee.


What Do Knee Braces Do?

After facing issues with the knee that has reduced the overall stability of the joint, many individuals consider wearing knee braces. But what are the braces doing? How will they help?

There are a variety of different braces on the market, each designed with different characteristics to manage specific conditions and give the necessary support for each user. The main purpose of each knee brace is to either provide compression to the knee while managing inflammation or provide artificial stability through the use of rigid frames and/or hinges to the weakened joint.

Something To Consider

While many people who wear braces swear by their product, it is important to keep in mind that bracing is arguably the least important part of preventing and healing from knee injuries. Improving strength and flexibility of the knee are much more important to the health of the joint. Focus on stretching and strengthening the muscles surrounding the knee and consider improving daily biomechanics, such as when walking up stairs and kneeling at work.

While knee braces can be very beneficial while injuries are healing, painful joints need offloading or you are protecting the joint during contact sports, it is important to not allow the brace to become a “crutch” and solely depend on it for stability. If the surrounding muscles, ligaments and tendons are not subjected to daily stresses, they will weaken and be even more prone to injury.
