title: Factors affecting outcome in tibial plafond fractures.
abstract: To determine what fracture- and patient-specific variables affect outcome, 29 patients with 32 tibial plafond fractures were evaluated at a minimum of 2 years from the time of injury (range, 24-129 months; average, 46.5 months). The rank order method was used to assess severity of injury and accuracy of articular reduction on radiographs and agreement among the five surgeons was excellent with intraclass correlation coefficients of 0.93 and 0.94. Outcome was assessed by four independent measures: a radiographic arthrosis score, a subjective ankle score, the Short Form-36 (SF-36), and the patient's ability to return to work. The four outcome measures did not correlate with each other. Radiographic arthrosis was predicted best by severity of injury and accuracy of reduction. However, these variables did not show any significant relationship to the clinical ankle score, the SF-36, or return to work. These outcome measures were more influenced by patient-specific socioeconomic factors. Higher ankle scores were seen in patients with college degrees and lower scores were seen in patients with a work-related injury. The ability to return to work was affected by the patient's level of education. This study highlights the difficulties of predicting patient outcome, after these severe articular fractures.
