Evaluation of patellofemoral congruence in young adults with painful knees

ABSTRACT

Sixty one young adults 13 to 35 years of age, complaining of knee pain without a history of trauma or evidence of arthiritis, were examined clinically and radiologically to assess the patellofemoral congruity. The quadriceps angle and patellar height were measured by Insall Salvati ratio and Blackburn and Peel ratio. Merchant technique was used to measure the sulcus and congruence angles. The study showed the presence of a variable degree of patellofemoral incongruity in these patients and so stressed the importance of assessing this articulation whenever knee pain in a young adult is present
