Abstract
Patellofemoral pain dysfunction is
common in young females and athletes.
Retropatellar pain during walking and
inclination results in functional and social
disability. It has been documented that
patellofemoral pain syndrome is highly
correlated to the malposition or
malalignment of the patella, especially
lateral tilt of the patella. The possible
mechanism is that lateral force pulling
patella outwards in patients with laterally
tilted patella increases compression force
on the lateral facet of the patella, leading to
wear in the articular cartilage. Therefore,
controlling the lateral pulling force of the
patella is the main strategy to treat patients
with patellofemoral pain syndrome.
Clinically, functional foot orthoses have
been reported to have dramatic effect in
treating patellofemoral pain, but none of
them is done on the base on the controlled
studies. The purpose of this research,
therefore, was to investigate the effect of
functional foot orthoses on transverse
rotation and foot structure in patients with
patellofemoral syndrome.
The specific aim of the first-year
research was to investigate the immediate
effect of functional foot orthosis on
transverse rotation of the lower extremity in
patients with patellofemoral pain syndrome
and that of the second-year research was to
investigate the effect after 1 year. All of
research variables were measured for 3
different conditions, including barefoot,
wearing shoes, or wearing functional foot
orthoses. The patella position, navicular
height, both in relaxed and in subtalar
neutral positions, were measured using
Vicon 250 system. The trajectory of the
tibial rotation and foot pronation was
analyzed to understand the relationship of
foot deformity and patellar lateral tilt.
Results showed that there was
singnificant difference in the navicular
height and tibial rotation between the
experimental and control group, but not in
the percent of the center of pressure
relative to the foot length during quiet
stance. It implies that patients with
patella tilt syndrome may have a pronated
foot that exaggerates the clinical
symptoms. Functional foot orthoses can
relieve their symptoms through controlling
excessive foot pronation but doesn’t
change the whole structure of the foot.
