The purpose of this study was to examine the patellar angular position and its relationship with pain and functional ability in athletes with lateral patellar compression syndrome. From the men and women athletes with LPCS that have symptoms of this disorder only in one knee, 25 people were selected and its contralateral knee was considered as control group. Assessing the joint pain and functional ability were done by VAS and WOMAC scales, respectively and assessing the patellar alignment was done by digital radiology. Data were analyzed by independent t and Pearson Correlation tests. Tilt angle (P=0.001), lateral shift (P=0.003) and congruence angle (P=0.001) of patella were significantly more in symptomatic knees than in asymptomatic knees. Patellofemoral pain was significantly correlated with tilt angle (P=0.001) and congruence angle (P=0.008). Also, functional ability was significantly correlated with tilt angle (P=0.003) and congruence angle (P=0.001). Based on the results of this study, it is suggested that the main priority of the therapeutic protocols for such patients be to correct the patellar alignment.
