•against the femoral condyles with the knee in full extension, tenderness on palpation of the posterior edge at the medial and/or lateral border of the patella, and pain on direct compression of the patella against the femur during isometric quadriceps contraction
•with the knee in slight flexion; age between 12 and 40 years old; the presence of patellofemoral pain for
