Double level osteotomy for genu varum deformity
155
Conclusion
According to these results, computer-assisted
double level osteotomy in severe genu varum,
is a reliable, reproducible, and accurate
technique. This procedure, which is very
delicate, especially in reaching pre-operative
objectives,issimplifiedbycomputer-assistance.
The functional results are satisfying and the
satisfaction of the patients is very high. Despite
the difficulty of the procedure, complications
are, in our hands, very rare. We recommend
DLO for severe genu varum deformity in young
patients to avoid oblique joint line, which will
be difficult to revise to TKR.
