WebThe force transmitted to the patella by the retinacula is small in all knee positions. Because the rigid patella has its own lever arms and tendon insertions at different heights, the forces on patellar and quadriceps tendons are unequal. The small patellar contact areas change according to flexion and are dependent on quadriceps force. http://www.iaeng.org/publication/WCE2013/WCE2013_pp1929-1932.pdf
