ABSTRACTForty-five patients presenting neither patellar-femoral affection records nor X-ray or arthroscopic evidence of the disease were studied by determining through arthroscopy the contact of patella lateral facet, vertex and medial facet with the femur (thigh-bone) while the femoral-tibial joint was flexed. We found a standard mean of 33.4° for the lateral facet, with a standard deviation of 10.2°; 42.5° for the vertex, with a standard deviation of 10.8°, and 43.1° of femoral-tibial flexion for de medial facet, with a standard deviation of 11.3°. We observed some differences with respect to sex because there is a more precocious patellar-femoral contact in women than in men, agreeing with our previous researches and obtaining a framework for the normal patellar-femoral slip in our population
