BACKGROUND: Genu recurvatum is a debilitating deformity of the knee that can progress during growth and lead to significant deformity if left untreated. Recurvatum can be osseous, ligamentous, or mixed. Osseous genu recurvatum is most often due to asymmetrical growth arrest of the proximal tibial physis affecting primarily the tibial tubercle. Several methods have been described in the literature regarding the correction of this deformity; nevertheless, there is a paucity of knowledge of the correction of proximal tibial recurvatum using the Ilizarov technique.
METHODS: A retrospective chart and radiographic review of all patients treated by distraction osteogenesis with angular correction distal to the tibial tubercle using an Ilizarov external fixator was performed. A total of 9 patients were treated during the study period and the average age at the time of surgery was 14.3 years (range, 7-16 y). There were 3 female patients and 6 male patients. Four cases were due to deformity secondary to trauma and the treatment thereof, 2 patients had spondyloepiphyseal dysplasia, and 3 patients had unknown etiology. The angle of recurvatum (RG) and the angle of tilt of the tibial plateau (RT) preoperatively measured 28 degrees (range, 18 to 32 degrees) and 69 degrees (range, 60 to 82 degrees), respectively. At final follow-up, the RG and RT measured 7 degress (range, 4 to 12 degrees) and 93 degrees (range, 86 to 100 degress), respectively. Using the scoring system of Lecuire and colleagues, the overall results were good to excellent at a mean follow-up of 4.4 years.
CONCLUSIONS: Correction of osseous proximal tibial recurvatum by the Ilizarov method, allows obtaining an improved sagittal mechanical axis in the lower extremity.
