title: Hallux valgus in patients with patellofemoral pain syndrome.
abstract: The aim of this study was to investigate the presence of hallux valgus (HV) in patellofemoral pain syndrome (PFPS). Ninety-nine patients with unilateral patellofemoral pain participated. The study was designed with each subject acting as their own internal control by using the unaffected limb for comparison. The HV and intermetatarsal angles were measured by weight-bearing anteroposterior radiographs in patients. Eighty-four out of 99 patients had an abnormal HV angle on the affected side and 78 of 99 patients had an abnormal HV angle on the unaffected side. There were significant differences in the HV angle between affected and unaffected sides (P = 0.003). This study is the first to demonstrate the relationship between HV and PFPS. Further comprehensive biomechanical studies are warranted to analyse the relationship between HV and PFPS.
