title: Patient-based outcomes after clubfoot surgery.
abstract: Despite decades of experience in the area of clubfoot repair, considerable uncertainty remains regarding indications, surgical technique, and long-term results of treatment. Much of this uncertainty is due to the lack of a standardized and valid method for assessing postoperative outcomes of clubfoot repair. The current study used various end points to compare traditional and patient-based outcome measures and to develop a disease-specific instrument that is both meaningful to the patient and statistically valid. A cohort of 46 patients was identified, and several types of outcomes data were collected, including traditional end points of outcome (range of motion and radiographic criteria, qualitative patient-based data) and a previously validated instrument measuring pediatric functional status (FSIIr). At an average follow-up of 45 months, radiographic measures and range of motion were comparable to values published in previous studies. Postoperative functional status, as measured by the FSIIr, did not differ from that of age-matched controls. Psychometric analysis of these data allowed us to generate a 10-item disease-specific instrument (DSI), which conveyed patient-based attitudes toward outcome.
