Patellar instability.
[trochlear dysplasia]
Patella
instability
can
cause
significant
pain
and
functional
limitations
.
Several
factors
can
predispose
to
patella
instability
,
such
as
ligamentous
laxity
,
increased
anterior
TT-
TG
distance
,
patella
alta
,
and
trochlear
dysplasia
.
Acquired
factors
include
MPFL
injury
or
abnormal
quadriceps
function
.
In
many
cases
,
first
-time
dislocation
can
successfully
be
managed
with
physical
therapy
and
other
nonoperative
management
;
however
,
more
than
one
dislocation
significantly
increases
the
chance
of
recurrence
.
Surgical
management
can
improve
stability
,
but
should
be
tailored
to
the
injuries
and
anatomic
risk
factors
for
recurrent
dislocation
.
Isolated
lateral
release
is
not
supported
by
current
literature
and
increases
the
risk
of
iatrogenic
medial
instability
.
Medial
repair
is
usually
reserved
for
patients
with
largely
normal
anatomy
.
MPFL
reconstruction
can
successfully
stabilize
patients
with
medial
soft
tissue
injury
but
is
a
technically
demanding
procedure
with
a
high
complication
rate
and
risks
of
pain
and
arthrosis
.
Tibial
tubercle
osteotomy
can
address
bony
malalignment
and
also
unload
certain
articular
cartilage
lesions
while
improving
stability
.
Trochleoplasty
may
be
indicated
in
individuals
with
a
severely
dysplastic
trochlea
that
can
not
otherwise
be
stabilized
.
A
combination
of
procedures
may
be
necessary
to
fully
address
the
multiple
factors
involved
in
causing
pain
,
loss
of
function
,
and
risk
of
recurrence
in
patients
with
patellar
instability
.
