Severe Genu Recurvatum after a Closing-wedge High Tibial Osteotomy - A Case Report -
Abstract
Although a closing wedge high tibial osteotomy can decrease the posterior tibial slope, there are no reports of severe genu recurvatum after a closing wedge osteotomy that required corrective surgery. A 54-year-old male with medial compartment osteoarthritis and genu varum was treated with a closing wedge high tibial osteotomy in another hospital, which led to severe recurvatum because of surgical failure. He complained of knee pain and a severe deformity, but of which were corrected by an open wedge corrective osteotomy, a two-wedge bicortical autograft reconstruction, and double plate fixation. Surgeons should pay close attention to both varus deformity correction and changes in the posterior tibial slope during a closing wedge high tibial osteotomy.
Fig. 1
Preoperative radiographs of a 54-year-old male showing genu varum with medial compartment osteoarthritis. The femorotibial angle was varus 5 degree and the tibial posterior slope was 7 degrees.
Fig. 2
Three months after the closing wedge osteotomy in another hospital, postoperative radiographs show the correction of genu varum but severe genu recurvatum. The femorotibial angle was valgus 2 degrees and the tibial posterior slope was -15 degrees.
Fig. 3
Ten months after the closing wedge osteotomy, radiographs show persistent genu recurvatum and loss of valgus correction. The femorotibial angle was varus 2 degrees and the tibial posterior slope was -14 degrees.
Fig. 4
Four months after the corrective osteotomy, radiographs show the correction of genu recurvatum and genu varum. The femorotibial angle was valgus 5 degrees and the tibial posterior slope was 4 degrees.
Fig. 5
A standing AP radiograph, 14 months after the corrective osteotomy, shows normal alignment compared to the opposite knee. The femorotibial angle is valgus 3 degrees in the right knee and valgus 4 degrees in the left knee.
Fig. 6
Photographs, 14 months after corrective osteotomy, show normal alignment and correction of the genu recurvatum.
