[The treatment of genu recurvatum (author's transl)].

50 cases of genu recurvatum were classified into three types: osseous (malunion, epiphysiodesis), capsular and ligamentous (congenital hyper-extension, sequelae of old ligament rupture) and combination of the two types. The author's have analysed the results of 44 surgical procedures. The main procedure practised has been an opening wedge osteotomy of the upper end of the tibia above the level of the tibial tubercle with a graft to fill the gap. It is important to avoid distal displacement of the patella by detachment of the tibial tubercle and reattachment more proximally at the end of the surgical procedure. Osteotomy is always indicated but should be combined with a capsular repair or combined types. The results are satisfactory especially in cases due to premature closure of the growth plate.
