Medial
femorotibial osteoarthritis of the knee with genu varum is almost
always associated with metaphyseal varus. Ideally, this deformity
should be corrected at its very site, i.e. in the medial tibial metaphyseal
area, by medial opening tibial osteotomy.
This osteotomy restores the anatomy of the tibial metaphysis thereby
facilitating subsequent arthroplasty, unlike lateral closing tibial
osteotomy which is responsible for metaphyseal malunion.
Use of the Anthony K system eliminates
all of the classical disadvantages of medial opening tibial osteotomy
and allows :
