KNEE PAIN IS
A COMMON
COMPLAINT
IN PEOPLE
OF ALL AGES
AND ACTIVITY
LEVELS.
Pinpointing the cause of the pain can
be challenging. While many imaging tests
provide a clear picture of the knee at rest,
that doesn't always give doctors enough
information to make a diagnosis.
The innovative KneeKG assessment
device shows what happens when the knee
is in motion. The new technology-now
available at Penn Medicine Lancaster
General Health Physicians Sports Medicine-can help to identify the cause
of knee pain and lead to more effective
treatment.
A KneeKG assessment is noninvasive
and can be completed in about 10 minutes. Patrick J. Moreno, MD, of Sports
Medicine, located at LG Health Kissel
Hill in Lititz, said that for certain patients,
KneeKG offers additional advantages over
other imaging tests.
"There are many imaging studies available, including X-ray and MRI, to show
what the knee looks like at rest," he said.
"KneeKG can help us to see what happens
when the knee is in motion, which is when
people most often experience knee pain."
KneeKG was developed by the Montreal-based health-care technology

company Emovi. Prior to its rollout
at Sports Medicine, Emovi tested the
KneeKG technology at Lancaster's Smart
Health Innovation Lab. In addition to its
other benefits, KneeKG comes at a lower
cost than many traditional imaging tests.

By showing the knee in motion, KneeKG
can help to diagnose gait problems,
patellofemoral syndrome (or "runner's
knee"), and ligament damage, as well as
issues related to arthritis, muscle tightness,
or weakness, he said.

LG Health is one of four partners in the
lab, which offers guidance and support to
startup companies seeking to accelerate
development of their health-care innovations. Following KneeKG's successful
testing at the lab, Emovi and the lab team
partnered with Sports Medicine to develop
a clinical model for using the technology
at LG Health.

Ben Adams, PT, a physical therapist
who works with Sports Medicine's patients
at Kissel Hill, said KneeKG can enhance
effectiveness of care for people with knee
pain by helping to guide clinicians in developing targeted physical therapy treatments.

During a KneeKG assessment, the patient
wears a brace-like device while walking on
a treadmill. The use of 3-D motion capture
technology helps the patient's physician
and physical therapist pinpoint the source
of the problem and develop a customized
plan of care.
"The KneeKG assessment gives us very
precise information on the biomechanics
of the knee, or how it moves through the
patient's natural gait," Moreno said. "The
results can often help us determine the
underlying cause of a patient's knee pain."
Still images from an MRI or similar
imaging technology show only the structure
of the knee at rest, he said. However, many
cases of knee pain do not originate from
an obvious trauma or specific injury, and
pain persists despite no apparent structural
damage. That's when a KneeKG assessment
can be especially beneficial.
"MRI remains the standard of care for
knee injuries such as ACL or meniscus tears,"
Moreno said. "But sometimes a patient is
having pain, and the MRI doesn't show an
obvious problem. In those cases, KneeKG
can help us identify problems that may not
be apparent in an MRI."

"KneeKGĀ helps us to create a very precise
PT treatment plan by identifying movement
patterns in the knee that aren't visible to
the naked eye but may be causing pain or
putting the patient at risk for injury," he
said. "The PT treatment plan is optimized
to correct these underlying biomechanical
stresses in order to alleviate pain or reduce
injury risk."
Interestingly, Moreno said, the COVID19 pandemic has brought more patients to
Sports Medicine with cases of knee pain
stemming from biomechanical issues.
KneeKG can be especially helpful in diagnosing these types of cases.
There may be several reasons for the
increase, Moreno said. More people are
moving away from gyms or trying new
exercises. People who are used to working
with a personal trainer or gym instructor
are now trying virtual workouts or high-intensity training, which involves frequent
jumping and landing, on their own. All
of these factors can increase the potential
for injury.
