We present a retrospective study investigating the results of the subjective assessment of displaced intra-articular calcaneal fractures in a selected cohort of 42 patients treated operatively, with a follow-up duration of at least 3 years. The adjusted American Orthopaedic Foot and Ankle Society questionnaire, Foot Function Index, and visual analog scale were used to quantify the subjective evaluations. Our hypothesis was that good subjective results could be predicted and obtained in patients with specific characteristics if anatomic reduction of the fracture was achieved. The results of the study confirmed our hypothesis. A number of specific subgroup analyses were undertaken. The study confirmed that Böhler angle restoration and the quality of reduction of the subtalar joint facet are important prognostic factors related to the outcome. In contrast, gender and Sanders type had less influence at the intermediate-term follow-up results. The main weaknesses of the present study included its retrospective nature, the lack of a control group managed nonoperatively for comparison, and the small sample size. Moreover, the operating surgeon performed the radiographic measurement and categorized the quality of the surgical reconstruction.
