The figure is taken from a paper (Am J Sports Med 2004 32: 477) on injuries to the anterior cruciate ligament due to forces applied by the patella tendon. Take a particular case where the attachment force on the tibia is 5610N when the leg is oriented with patella tendon tibial shaft angle of 13.2° and a knee flexion angle of 18.8°. What is the force on the patella tendon and what are the vertical and horizontal components of the force?
I cannot access the figure, and need it to answer the question.
