Introduction
TPatellofemoral pain may be caused by an increase of the pressure of the joint surfaces in the patella and the femur, and, as a consequence, a premature abrasion of joint cartilage. The aim of the study was an ultrasonographic evaluation and comparison of articular cartilage of the femur condyles between the limbs in patients with an elevated Q angle.

Methods
The total of 13 women aged 35–45 years with the Q angle exceeding 15° took part in the research. The measurement of the Q angle was carried out with a goniometer. The thickness of joint cartilage was measured with the ultrasound scanner HONDA HS-2200. Shapiro-Wilk test for normality was applied. The variance test ANOVA for independent samples allowed to evaluate the differences of the measured parameters. The Bonferroni test was applied for multiple comparison.

Results and conclusions
The analysis did not depict any statistically significant differences in the thickness of cartilage of the lateral condyle (p = 0.83) or the medial condyle (p = 0.12), or in the Q angle (p = 1.00) between the right and left limb. The changes in thickness of the joint cartilage covering the lateral and medial condyles occurred symmetrically in both limbs.
