Understanding the Patellar Syndrome in Sportspersons

The patellar syndrome or patellofemoral syndrome is the most frequent knee injury in sportspersons. It affects around 30% of sportspersons according to recent studies, i.e. millions of people, no less! It seemed important to letting you properly understand this pathology to reduce appearance risks.

What’s the Patellar Syndrome or Patellofemoral Syndrome?

The kneecap abnormally moves through the femoral groove (misalignement of the kneecap ). This causes unusual rubbing, which contributes to inflaming and damaging the patellar cartilage . Cartilage is like a thin coat of paint covering the kneecap and which allows a smooth sliding of the kneecap on the femur. The pain appears when the kneecap stays too long against the femur, like when sitting and/or when repeating the same shocking movement such as running.

Signs of patellar syndrome in daily life.

  • Discomfort and pain when being in a sitting position for a long time (need to stretch the leg and to 'crack' your knee);
  • Pains when going down stairs;
  • Your knee often cracks;
  • You feel like your kneecap disengages from its tracks and reengages almost instantly;
  • You feel crunching feeling inside the knee, and a sensation of heaviness of the knee.

Predisposing factors to the Patellofemoral Syndrome appearance

  • You have flat feet or feet in pronation.
  • Your knees point towards the inside (genu valgum), or towards the outside (genu varum).
  • You have a leg shorter than the other.
  • The muscles that surround your kneecap do not exercise the same forces and contribute to an imbalance of the patellar support.
  •  A few extra pounds that add pressure on the kneecap and make it more fragile and sorer.

In any case, when you’re doing sport with those predisposing factors, the kneecap does not slide in its natural tracks. This causes an abnormal rubbing between the femur and the kneecap , which is responsible for the more or less bothering pain you can feel in your knee joint . Moreover, if you’re running, hiking, biking, or even if you play football or basketball with a patellar syndrome , the discomfort and the pains can be different.

Consequences of a non-treated patellar syndrome

The unnatural rubbing of the kneecap against the femur leads to a complete deterioration of the cartilage , which surrounds and protects the kneecap . The direct consequence is knee arthritis .

That’s why it’s important to treat your patellar syndrome .

There are a lot of braces and kneepads dedicated to the patellar syndrome . However, only one has been developed for sport activities: the PHYSIOstrap™ SPORT*.
