Preoperative Planning

A full-leg X-ray with the patient in the standing position is recommended for preoperative
planning purposes. If this is not possible, an X-ray of the thigh, including the femoral
head, should be taken. The X-ray images of the knee joint at three levels should be
available for planning the surgery. A tangential patellar exposure, a frontal and a sagittal
to the leg axis exposure must be taken.

For preoperative planning there are X-ray templates available: with scale of 1.15:1 Lit. No.
1354 / 1355 and with scale of 1:1 Lit. No. 1511 / 1512 ( see page 89 ). The lateral view of
the condyles is decisive. If these are no longer completely intact, it is possible to switch
to the condylar width. In cases of doubt, the smaller implant should be selected to
prevent the prosthesis components from protruding. In normal cases, the size
determination and the correct positioning of the prosthesis are controlled intraoperatively
with relevant instruments and planning may also be possible on the unrestored opposite
side leg.

Important

The femoral and tibial component sizes can all be combined with the next size up
or down ( see product overview on page 90 ff ).

Large deviations of the femoral neck angle as well as severe deformities of femur and
tibia (

e.g.

posttraumatic

axial

deformities

)

must

be

taken

into

consideration during

surgical planning.

In

cases

of

deformities

away

from

the

knee

joint

that

adversely

i

nfluence the mechanical

axis, additional corrective osteotomies may be indicated.
