Early revisions of the Femoro-Patella Vialla joint replacement.
[trochlear dysplasia]
The
aim
of
this
study
was
to
review
the
early
outcome
of
the
Femoro-
Patella
Vialla
(
FPV
)
joint
replacement
.
A
total
of
48
consecutive
FPVs
were
implanted
between
December
2007
and
June
2011
.
Case-note
analysis
was
performed
to
evaluate
the
indications
,
operative
histology
,
operative
findings
,
post-operative
complications
and
reasons
for
revision
.
The
mean
age
of
the
patients
was
63
.
3
years
(
48
.
2
to
81
.
0
)
and
the
mean
follow-up
was
25
.
0
months
(
6
.
1
to
48
.
9
)
.
Revision
was
performed
in
seven
(
14
.
6
%
)
at
a
mean
of
21
.
7
months
,
and
there
was
one
re
-revision
.
Persistent
pain
was
observed
in
three
further
patients
who
remain
unrevised
.
The
reasons
for
revision
were
pain
due
to
progressive
tibiofemoral
disease
in
five
,
inflammatory
arthritis
in
one
,
and
patellar
fracture
following
trauma
in
one
.
No
failures
were
related
to
the
implant
or
the
technique
.
Trochlear
dysplasia
was
associated
with
a
significantly
lower
rate
of
revision
(
5
.
9
%
vs
35
.
7
%
,
p
=
0
.
017
)
and
a
lower
incidence
of
revision
or
persistent
pain
(
11
.
8
%
vs
42
.
9
%
,
p
=
0
.
045
)
.
Focal
patellofemoral
osteoarthritis
secondary
to
trochlear
dysplasia
should
be
considered
the
best
indication
for
patellofemoral
replacement
.
Standardised
radiological
imaging
,
with
MRI
to
exclude
overt
tibiofemoral
disease
should
be
part
of
the
pre-operative
assessment
,
especially
for
the
non-
dysplastic
knee
.
