Scorpio Trial Cutting Guide

Note: Femoral chamfer cuts cannot
be made with the TCG. However, if
bone loss is minimal and it is
determined that chamfer cuts are
required, the Scorpio Total
Stabilizer (TS) All-In-One Cutting
Block may be used to make
chamfer cuts (Lit. No. LSTS/ST,
Page 8).

Joint Line Restoration

Insert the TCG into the femoral canal

(Figure 7)

and align the TCG medial

epicondyle (ME) scribe line reference mark
with the medial epicondyle 

(Figure 8)

. The

ME scribe line is 28mm from the distal
surface of the TCG. When the ME scribe
line is in line with the medial epicondyle,
the distal surface of the TCG will be
approximately located at the joint line.
(The joint line can also be estimated
using pre-operative radiographs and
anatomic landmarks.)

Place an initial fixation pin in the middle
of the medial slot on the TCG 

(Figure 9

and Figure 10)

. Pinning the medial slot

will fix the proximal/distal position while
allowing for slight internal and external
rotation of the TCG.
