[Osteotomy in the prosthetic substitution of severe axial deviation of the knee]

Arthroplasty can be a successful treatment for arthritis even in cases of severe axial deviation of the knee. Since significant bone loss is often present in these cases, the technique and extent of the resection is very important. In this paper we review our series and compare it with solutions proposed by other authors, focusing our attention on the techniques of resection and replacement of lost bone employed in order to achieve optimal axial alignment and anchoring of the prosthetic components.
