ESPARRAGOZA MONTERO, Ricardo E et al. Relación entre la inclinación troclear femoral lateral y la condromalacia patelar evaluada con imágenes de resonancia magnética y artroscopia. RFM [online]. 2008, vol.31, n.2, pp.86-91. ISSN 0798-0469.

The patellar chondromalacia is associated to rotulian instability. The lateral femoral troclear inclination is linked to patellar inestabily; however, there are not studies about linking it to patellar chondromalacia. 39 patients of both genders were included; age range between 13-74 years, who underwent magnetic resonance and arthroscopy of the knee. The sensitivity and specificity of the magnetic resonance for patellar chondromalacia were 84 % and 71.4 %. Mild cases were more frequents in men and younger subjects. Moderate and severe grades were more frequents in the femenine gender and affect older patients. There were not significant differences between the values of lateral femoral troclear inclination of the patients with and without chondromalacia patellar. However, the lateral femoral troclear inclination was lower in the severe patellar chondromalacia, particularly in comparison to moderate cases (17.6ºvs.21.8º, P=0.06). The lateral femoral troclear inclination and patellar instability could be associated to severe patellar chondromalacia; They may be according the progression of the disease.
