Since its launch in 2015, the Rebound PCL brace from Össur has been recommended in rehabilitation protocols for PCL and complex knee injuries worldwide and is used by many key opinion leaders
The posterior cruciate ligament (PCL), compared to the anterior cruciate ligament (ACL), has the intrinsic ability to heal and regain continuity after an injury (1). The PCL experiences variable tensile forces during knee flexion (2). Insufficient healing after a PCL rupture can lead to significant pathologies, such as chronic knee pain or knee OA (2). In a PCL deficient knee, gravity and the forces on the joint from the hamstring muscles can potentially cause the tibia to be positioned in a posterior subluxed location relative to the femur (posterior sag) (1). Healing of the PCL in an elongated position can lead to chronic instability and disability. Therefore, anatomically correct positioning during conservative or surgical rehabilitation is important.
The Rebound PCL brace is designed to apply a physiologically correct, dynamic force, providing a more optimal joint environment for rehabilitation of posterior cruciate ligament (PCL) ruptures, whether during functional (non-surgical) treatment or post-surgical reconstruction. The Rebound PCL can also be used for complex ligament reconstruction with PCL injury.
The dynamic load of the Rebound PCL on the tibia is generated by applying an anterior directed dynamic force on the calf area and opposing counter forces on the anterior aspect of the leg. The Rebound PCL allows for specific load adaptation according to the patient’s individual anatomy and rehabilitation related requirements.
The Dynamic Tension System™ increases the load on the tibia as the knee goes through flexion, applying an Anterior Drawer force designed to optimise the rehabilitation of the healing PCL. Previous PCL braces have either not sufficiently supported the PCL or only provided a static force to support the PCL (4), leading to forces that are by far too high in knee extension, insufficient support at 90° of knee flexion, or a mix of both.
Several clinical papers have been published on the biomechanical function and clinical outcomes of the Rebound PCL, and most recently its use as a recommended gold standard brace in PCL and posterior-lateral corner (PLC) rehabilitation (5, 6, 7, 8, 9, 10). Find the data and more information here.
