Anterior knee pain, patellar instability –
who does it affect?
Widespread anterior knee
pain can be caused by patellar instability. A
colleague once said that half of North Rhine
Westphalia is affected by this condition.
Anterior knee pain is certainly very common.
It mainly affects girls and young women.
What causes subluxation of the kneecap?
Subluxation occurs when
the patella can no longer move easily in its
natural trochlear groove. A valgus position
ing of the kneecap worsens the situation.
Instability is usually lateral. Overexertion
in sport can be a cause. Local overexertion
of the patellofemoral structures is often
caused by lateralization of the patella.
With a tendency towards luxation?
There is a risk. Luxation
should be avoided at all costs, as bone struc
tures could become damaged too – a clear
indication for surgery. In addition, after a
first luxation, the risk of a relapse is greatly
How can you avoid luxation and what
can you do to treat anterior knee pain?
should always be tried first when treating
the patella. One of the biggest challenges
is: how can I improve the situation by
strengthening the muscles? The central
muscle is the vastus medialis muscle, which
guides the patella by means of the tendon
attachments. Physiotherapy is required as
the first step. Suitable training in conjunc
tion with supports that stabilize the patella
can reduce the symptoms.
Which characteristics must these supports
Focus on the patella is
important. Many supports have a ring to
center the kneecap. This does not have
enough effect however. To convince patients
and orthopedists, wearing comfort and,
above all, effectiveness must be well docu
mented. Such as a certain function of the
GenuTrain P3, which played a significant role
in the observational study at our clinic ...
You mean the corrective strap, that can be
and by the patients
themselves – an inconspicuous strap, wound
around the patella in the right place. The
patella corrective strap is no wire rope, but
it works! Patients can adjust it to make it
tighter or looser, depending on the level of
instability or how it feels to them. In this
way, it can contribute to an improvement.
What do you think of the GenuTrain P3’s
other features, like the patella cover and the
You have to consider the
support as a whole. The combination of all
of the characteristics and functions should
be coherent. That includes the muscle-
relaxing pad. It can act as an antagonist
for the vastus medialis muscle by relaxing
its partner, the vastus lateralis muscle. This
can avoid a tipping or lateralization of the
What is your conclusion on the newly
redesigned GenuTrain P3?
Before the observational
study, I admit I was skeptical. However,
the medical-clinical evaluation surprised
me. The support can help to reduce pain
in cases of anterior knee pain and reduce
the risk of luxation of the kneecap. It is
especially important for young women,
who take great care with their appearance,
that their support is an effective treatment
and motivation aid – it helps them to help
In cases of patellar instability, luxation as the first manifestation must be avoided at all costs,
stresses Dr. Bernd Lasarzewski, Head Physician at the Knee, Shoulder and Elbow Surgery
Department at the Hellersen Sports Clinic in Lüdenscheid. The team physician for the national
women’s football team thinks a seemingly insignificant strap can help.
