Sonographic assessment of the extensors of the knee in patients with anterior knee pain syndrome and in control group is presented. Both groups were similar in respect of age and sex. The assessment was done according to Heckmatt. Resting transverse sizes of rectus, intermedius, vastus lateralis and vastus medialis were related to their sizes during isotonic contracture under load. Statistical analysis has been done with Mann-Whitney test. Statistically significant weakening of rectus femoris, intermedius (p < 0.00001) and vastus medialis (p < 0.01) have been found in anterior knee patients. These might explain patellar malalignement in this group.
