The Patelladysplasie is a malformation of the kneecap (patella), wherein this has an asymmetrical shape.
causes
The asymmetry of the patella is mostly congenital, but it can also occur as a result of an accident.
Symptoms
Due to the asymmetry, constant stress on the kneecap results in uneven abrasion of the underlying cartilage layer. Depending on the severity of the patellar dysplasia, this can lead to considerable pain in childhood or cause no discomfort for decades. Initially, patellar dysplasia is usually not noticed directly and the person affected complains of moderate to severe discomfort when exposed to stress and, depending on the extent, also in everyday situations (bending over, sitting down). In many of those affected, patellar dysplasia becomes noticeable in relaxation and rest situations (such as lying down, going to sleep). Depending on the damage to the cartilage layer, patellar dysplasia can be acoustically noticeable in that the knees crunch when bent under load. If the cartilage wear is already more advanced, pain occurs. Many bruises can also be a sign of advanced patellar dysplasia.
diagnosis
Depending on the severity, the specialist can recognize an asymmetry in the kneecap with the naked eye. This diagnosis is confirmed by an X-ray of the bent knee.
therapy
Therapy options are directly dependent on the progress of the cartilage damage. A reconstruction of a destroyed cartilage layer is not possible, so it is a matter of preventing further progression, remaining cartilage should be preserved. Protecting the knees from excessive strain and building up the muscles around the knees are common measures. The orthopedic surgeon usually issues a prescription for the physiotherapist .
