Lateral unicompartment knee arthroplasty (UKA)
125
Fig. 5A and 5B - The
femoral implant doesn’t
be too large to avoid an
impingement in front of
the trochlea, causing
conflict with the patella
which is easily con
trollable.
Fig. 5C and 5D - The
femoral implant doesn’t
be Undersize : it must
cover
correctly
the
posterior condyle.
Fig. 6 - The goal in the end of surgery is to have a
small security laxity (of 2 to 3mm with stress).
Without ligament release, this small laxity is a good
indicator of the absence of overcorrection in frontal
plane.
