Reduced Anterior Knee Pain

By increasing the length of the moment arm, the Scorpio Knee System helps to reduce patello-femoral joint reaction forces. Muscle force and body weight determine the degree of patello-femoral joint reaction force, which frequently contributes to anterior knee pain following TKA. Reduced stress on the joint would decrease the likelihood of anterior knee pain, particularly when patients rise from a chair, climb and descend stairs, and walk long distances. Traditional knee designs with a short patello-femoral moment arm increase joint reaction force, and may increase the potential for anterior knee pain. With its longer patello-femoral moment arm, the Scorpio Knee System decreases the potential for anterior knee pain.1
