Patellofemoral arthroplasty: outcomes and factors associated with early progression of tibiofemoral arthritis.
[trochlear dysplasia]
The
purpose
of
this
study
was
to
review
the
results
of
patellofemoral
arthroplasty
(
PFA
)
performed
by
a
single
surgeon
at
a
single
institution
in
order
to
determine
factors
associated
with
clinical
outcomes
and
progression
of
tibiofemoral
degenerative
joint
disease
.
Sixty
-
one
patients
with
isolated
patellofemoral
osteoarthritis
were
treated
with
a
PFA
by
a
single
surgeon
between
2003
and
2009
.
Fifty
-
nine
patients
were
available
for
analysis
with
a
mean
follow-up
of
4
years
(
range
2
-
6
years
)
.
Patients
were
evaluated
by
measuring
range
of
motion
and
with
the
use
of
the
Knee
Society
clinical
rating
system
,
the
Tegner
Activity
Level
Scale
,
and
the
UCLA
Activity
Score
.
In
addition
,
preoperative
radiographs
were
evaluated
for
patellofemoral
and
tibiofemoral
compartment
osteoarthritis
and
presence
of
trochlear
dysplasia
,
and
post-operative
radiographs
were
reviewed
for
progression
of
tibiofemoral
degenerative
arthritis
.
Furthermore
,
multivariate
statistical
methods
were
applied
to
study
factors
that
had
potential
to
influence
the
final
outcome
.
There
was
no
statistically
significant
association
between
age
,
gender
,
history
of
prior
knee
surgery
,
patellar
height
,
patellofemoral
osteoarthritis
severity
,
patellar
and
femoral
component
size
,
or
performance
of
lateral
release
with
patient
pain
and
function
(
as
measured
by
the
Knee
Society
scores
)
or
progression
of
tibiofemoral
joint
osteoarthritis
at
final
follow-up
.
Increased
preoperative
body
mass
index
(
BMI
)
was
associated
with
lower
post-operative
Knee
Society
function
scores
(
p
=
0
.
03
)
.
Patients
with
preoperative
trochlear
dysplasia
had
significantly
less
radiographic
evidence
of
tibiofemoral
joint
osteoarthritis
progression
compared
with
patients
without
trochlear
dysplasia
at
final
follow-up
(
p
<
0
.
0001
)
.
In
this
study
,
patients
with
preoperative
radiographic
evidence
of
trochlear
dysplasia
experienced
less
progression
of
tibiofemoral
degenerative
joint
disease
than
patients
without
trochlear
dysplasia
at
a
mean
follow-up
of
4
years
.
