Abstract
Recurvatum genu can develop as a results of both chronic diseases “maladie des enfants alités” (Lefort), though rarely, and after trauma, which occurs more often. Surgical treatment might consist either in a de-epiphysiodesis according to Langenskield, when a bone bridge is present, or by Ilizarov technique, which allows a correction of segmentary shortening.
This kind of trauma often occurs after bone growth has ceased and this is why in our study we performed osteotomies. Femoral osteotomies are all closed wedge procedures with medial access and 90° angle blade-plate fixation. This allows early mobilisation and avoids overcorrection. Without performing this kind of procedure posteriorisation of the trochlea might occur and, consequently, over time, patellofemoral arthritis could develop. For the tibia we applied an anterior open wedge osteotomy with ATT avulsion, according to Lecuire, with which secondary low patella can be avoided. As fixation we first used screws, actually a plate to correct the co-existing valgus.
The good results of this kind of surgery justify autologus bone graft. We have not employed the the procedure described by Bowen.
