Dynamic Bracing

Power When You Need It, Freedom When You Don't.

How Do They Work?

The dynamic series of braces use biomechanical technology, only applying force during the time of medical need, allowing for comfort and control not available with any other brace.

Ligament Instability

Dynamic ligament bracing uses movement and muscle power to apply a corrective force to help control the tibia and stabilize the knee joint. This force is then removed when the leg moves into flexion and control is not medically required. In reconstructed ligaments, dynamic braces can help to protect the repaired ligament.

Dynamic braces work with the body against pathological movements of the tibia providing increased stability and improved function when needed. Whether competing at the highest level of sport or lacing up for the weekend, patients will have the support they need to perform.

Dynamic Ligament Bracing

Dynamic bracing can be used for multiple types of ligament instability. The brace works with the body to control the tibia from moving out of proper alignment with the femur. Here is how the brace works in more detail depending on the injury.

ACL Injuries

One of the major issues when suffering from an ACL injury is the time it takes for the hamstrings to activate as the tibia moves into extension. When an ACL is torn or otherwise injured, control of the tibia has no defined end point. In an ACL deficient knee and even in a reconstructed ACL the hamstring response time is slowed by 2-3 times that of a healthy knee1. This means that the hamstrings are ineffective in controlling the movement of the tibia as you move into the final degrees of extension. As a result, just before the foot hits the ground, in the last 30 degrees of extension, the tibia naturally wants to move anteriorly and subluxes causing knee instability.

With a dynamic brace, a counterforce is applied to the front of the tibia during the last 30 degrees of extension. This counterforce keeps the tibia in proper alignment as the foot hits the ground providing increased knee stability.

PCL Injuries

When the PCL is torn or injured, as the knee moves further into flexion, the tibia naturally wants to move posteriorly. The dynamic brace uses the quadriceps and hamstrings power to work against the pathological movement of the tibia by applying a counterforce at 50-60 degrees of flexion to the back of the tibia pushing the tibia back into proper alignment.

Dynamic OA braces apply a corrective force to the leg progressively as it moves into extension. This is when the symptoms of OA are most severe. No pressure is applied when the leg is bent, for example, while sitting or driving a car. A dynamic brace is much more comfortable to wear for extended periods of time.

Dynamic OA braces can provide a comfortable solution for symptoms of unicompartmental OA and allow patients to get back to daily activities. Whether a weekend warrior or looking to spend more time with family, Dynamic OA braces help patients to spend more time doing what they love.


In a unicompartmental osteoarthritic knee, the articular cartilage has worn down on one side of the joint. Often times this results in discomfort during walking and running which can lead to a decrease in activity.

OA braces use corrective forces to align the knee joint reducing the discomfort that can be caused by OA. This reduction can allow the patient to return to activities of daily living and can also actually slow the progression of osteoarthritis. The symptoms of OA occur while weight-bearing when the leg is in extension.

Dynamic OA Bracing

In a dynamic brace a corrective force is only applied in the last 30 degrees of extension when the most relief is needed. That force is removed as the knee moves into flexion and symptoms are no longer present. For example, there is no pressure on the joint when sitting or driving a car.

With dynamic bracing, the brace is more comfortable to wear for extended periods of time. This allows patients to spend their time doing the things they love.

Patellofemoral Joint Disorders

Dynamic patellofemoral braces deliver progressive support and compression for PF injuries to enhance normal anatomic motion. They provide dynamic stabilization from terminal extension through 50 degrees of flexion to reduce discomfort, mal-tracking and subluxations. Once into deep flexion and the knee joint compresses, each brace relaxes allowing a full range of movement. This means an active brace, comfortably supporting patients when they need it most.

Dynamic patellofemoral braces provide support and stability at the time of medical need. They encourage normal anatomic movements and enhance stability so that patients can stay on their feet and compete with confidence.

Patellofemoral Joint Injuries

The Patellofemoral joint is a complex structure resulting in a myriad of conditions and injuries. Common conditions include mal-tracking, dislocating, and anterior knee discomfort. The underlying conditions often stem from anatomic predispositions, acute events or chronic degeneration. Due to the varied nature and complexity of conditions, Breg has developed individualized braces to address specific needs.

The FreeRunner

The FreeRunner provides maximum stability from the final 30 degrees of terminal extension. It uses a proprietary offset hinge to deliver a progressive force effectively creating a soft tissue lateral wall to reduce lateral translation of the patella. As flexion returns and the knee moves past 30 degrees, the FreeRunner relaxes, providing the freedom to perform.

The 20.50

The 20.50 is the only brace to provide maximum function in flexion. It uses an inflatable and an adjustable bladder to dynamically support the patellofemoral joint as the knee moves between 20 degrees and 50 degrees of flexion. Increasing the pressure on the lateral border of the patella, during flexion, maintains normal tracking and reduces the risk of additional injury, subluxation or dislocation for severe patellofemoral joint conditions. Once past 50 degrees and into deep flexion, the brace relaxes allowing a full range of motion. The 20.50 is lightweight, low profile and built to work with you and not interfere with your daily activities.
