[Double-Level De-Rotational Osteotomy of the Knee].

Abstract

Derotational osteotomies of the proximal tibia and distal femur are a common surgical treatment option in patients with a congenital or posttraumatic torsional deformity. Clinically, these patients present with isolated anterior knee pain alone or in in combination with patellofemoral instability. Since the combination of femoral and tibial deformity is common (quotation Cooke), a combined surgical treatment is needed for these cases. This includes high tibial derotational and a distal femoral osteotomy, stabilised by a plate respectively. The current video shows the technique of this combined osteotomy assisted by external fixateur and the tibial approach with tibialis anterior fasciectomy and neurolysis of the peroneal nerve.
