We compared the psychological characteristics of patients with the anterior knee pain syndrome and their matched controls. The evaluation was performed by means of the Minnesota Multiphasic Personality Inventory test (MMPI). We demonstrated that patients suffering from the knee pain syndrome presented greater caution, mistrust and suspicion in interpersonal relationships. Other typical features included: increased hostility, oversensitivity and inability to express negative emotions. These patients also reported unspecific somatic complaints. Their adaptability proved to be significantly lower than that of control subjects. We did not confirm a tendency towards passive attitudes. Scales measuring levels of depression did not reveal significant differences between the two groups. Present data revealed that anterior knee pain patients have significant psychological disturbances that might influence the course and outcome of treatment. Therefore, psychological evaluation should be performed and psychological therapy should be considered in all patients with the anterior knee pain syndrome.
