Parameters influencing complaints and joint function in patients with osteochondral lesions of the ankle-an investigation based on data from the German Cartilage Registry (KnorpelRegister DGOU)

摘要

Patients with osteochondral lesions of the ankle represent a heterogeneous population with traumatic, posttraumatic and idiopathic forms of this pathology, where the etiology of the idiopathic form is principally unknown. The aim of this study was to classify the heterogeneous patient population according to the patients' complaints and joint function. Data from the German Cartilage Registry (KnorpelRegister DGOU) was analyzed for this purpose to investigate whether traumatic and posttraumatic lesions cause more complaints and loss of joint function than idiopathic lesions. Moreover, it was sought to determine if lesion localization, defective area, stage, patient age, gender, and body mass index (BMI) are related to patients' complaints and loss of joint function.
