Lower limb support RAPTOR/2RA

Lower limb support RAPTOR/2RA




Posterior Cruciate Ligament (PCL) is strong, elastic bands of tissue, connecting tibia and femur. It’s more stronger than anterior cruciate ligament (ACL). PCL prevents the femur from sliding off the anterior edge of the tibia and to prevent the tibia from displacing posterior to the femur. Together with ACL forms knee joint.


Cruciate ligaments of knee allow us to live in active way. They support such physical activities as: jumping, swimming or running. Unfortunately, together with surrounding soft tissues, they may be damaged easily during daily activities. Very often, together with PCL, other ligaments and meniscus are torn.

The posterior cruciate ligament (PCL) is susceptible to injury during hyperflexion, hyperextension and in a mechanism known as a dashboard injury. PCL lies deep within the knee joint and due to this fact, high forces may torn it such as car accidents, which are 50% of total amount of isolated injury to the PCL. In this injury the knee experiences impact in a posterior direction during knee flexion toward the space above the tibia.

Furthermore, PCL injury is common in many sport disciplines. During sports activities, the PCL also can tear when an athlete falls forward and lands hard on a bent knee, which is common in football, basketball, soccer and especially rugby. Every sudden motion of knee twisting or jumping can result in ligament injury.
If you suffer from PCL injury, you can have one from 3 types of sprains, classified according to a traditional grading system:
1. Grade I – only microscopic tears in the ligament,
2. Grade II (moderate) – the ligament is partially torn, and the knee is somewhat unstable,
3. Grade III (severe) – the ligament is either completely torn or is separated at its end from the bone that it normally anchors, and the knee is more unstable.

In mostly cases (grade II and III), the treatment of injured posterior cruciate ligament do not require surgery and full recovery is achieved with physiotherapy and joint stabilization. In case of grade III, the surgery is necessary.

No matter if treatment is conservative or not, the professional knee ligament brace is crucial! The brace will provide knee stability and protect the PCL against further injuries.
To do that, many doctors and experts highly recommend our lightweight functional knee brace RAPTOR/2RA.
