Patellofemoral pain syndrome
Synonyms in a broader sense
Of the Kneecap pain is also known as femoral patellar pain syndrome designated.
Further synonyms are:
- Retropatella pain
- Chondropathia patellae
- Chondromalazia patellae
- patello-femoral arthralgia
- patello-femoral osteoarthritis
- PFS
- PFSS
- femoral patellar pain syndrome
Differential diagnosis of the patellofemoral pain syndrome
Differential diagnostics are alternative causes that cause comparable symptoms and complaints:
- Osteoarthritis of the knee
- Knee arthritis (inflammation of the Knee joint)
- Meniscus damage
- Ligament damage
- free joint body
- Leg length difference
- Radiation pain from the hip
or the Spine (referred pain)
definition
The PFFS (Patellofemoral Pain Syndrome) is one of the most common symptoms in anterior knee area.
The PFSS does not hide a uniform clinical picture, but rather a very complex symptom picture relating to Definition, diagnosis and Etiology (causes) is discussed very differently.
The definition of an Australian research group is: Pain originating in the anterior knee area and the patello-femoral region (the area of the articulated connection between the kneecap and the thigh bone) of mostly unclear cause.
The patellofemoral joint suffers from degenerative changes as early and often as hardly any other joint, and there is still no method for the reliable repair of Cartilage damage. Often young, physically active, more often female people are affected by PFFS (patellofemoral pain syndrome).
Appointment with a knee specialist?
I would be happy to advise you!
Who am I?
My name is dr. Nicolas Gumpert. I am a specialist in orthopedics and the founder of .
Various television programs and print media report regularly about my work. On HR television you can see me every 6 weeks live on "Hallo Hessen".
But now enough is indicated ;-)
The knee joint is one of the joints with the greatest stress.
Therefore, the treatment of the knee joint (e.g. meniscus tear, cartilage damage, cruciate ligament damage, runner's knee, etc.) requires a lot of experience.
I treat a wide variety of knee diseases in a conservative way.
The aim of any treatment is treatment without surgery.
Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.
You can find me in:

Unfortunately, it is currently only possible to make an appointment with private health insurers. I hope for your understanding!

Symptoms of Patellofemoral Pain Syndrome
- Pain in the area of Kneecap (behind, next to, under)
- Start-up pain after prolonged rest of the Knee joint
- Pain intensifies after exercise, when climbing stairs, when squatting
- Movement restrictions, feeling of tension through Swelling in the kneecap area
- Pain can occur on one side, on both sides or alternately
Causes of pain in the kneecap
- Bony Deviations of the kneecap and the knee joint (If one / Knock knees)
- Bony deviations of the hip or ankle joint
- Too tight kneecap guidance due to ligament shortening
- Muscle weakness in the thigh muscles
- Muscle shortening of the thigh, hip and calf muscles
- Classic overload of the knee joint
Pain from bony deviation of the knee
Due to an under-education of the Kneecap (patellar dysplasia), a forward displacement of the thigh or a so-called Patella alta (kneecap standing too high) there is an incongruent joint surface between kneecap and thigh (kneecap sliding bearing) with the consequence of poor guidance of the kneecap. A patella alta is understood to be a thigh muscle tendon that is too long in comparison to the longitudinal diameter of the kneecap (patellar tendon). As a result of these imbalances, the kneecap moves too far outwards (laterally) with increasing knee extension, the contact area of the joint is reduced and the Pressure load on the kneecap on the thigh increases. The consequence of this is irritation of the surrounding soft tissues, a Damage to the kneecap cartilage and Stress pain.
A x-leg position of the knee joint (Genu valgus) or one O-leg position (genu varus) also change the tension in the thigh extensor (M. quadriceps) and the position of the kneecap in its plain bearing on the thigh. A arthrosis (Cartilage degeneration) of the kneecap and knee joint cartilage is favored.
The kneecap cartilage needs adequate pressure and relief to stay healthy. As a risk factors for cartilage damage comes next to those described above structural Changes Above all, a lack of physical disposition, insufficient exercise and stress, as well as a disproportion between stress and resilience are in question.
