Patella stability

Frequency:Patellar instability occurs more frequently in adolescents.

Cause:The cause of patellar instability can be a misalignment of the kneecap, insufficient muscle tension or excessive strain on the knee during sporting activities. Often, connective tissue weaknesses or genetic factors also play a role and usually a combination of these factors.

Congenital or acquired:In most cases, patellar instability is acquired, but can be favoured by congenital deformities or weak connective tissue.

The most common symptoms include pain in the front of the knee, a feeling of instability in the knee and a noticeable displacement of the patella during certain movements. Those affected often report repeated dislocation of the kneecap.

Conservative:Treatment usually begins conservatively, with physiotherapy to strengthen the thigh muscles that stabilise the knee. This also includes targeted exercises to improve mobility and the muscles around the knee. In some cases, an orthosis can help to stabilise the knee.

Surgical:In more severe cases, with repeated dislocations or if conservative measures are not sufficient, surgery may be necessary. This often involves correcting the position of the kneecap or stabilising it by tightening ligaments and tendons.

It is important to start treatment early to avoid long-term damage.

Without treatment, patellar instability can lead to repeated dislocations and chronic pain. In severe cases, this can permanently restrict the mobility of the knee and lead to consequential damage.

With timely treatment, physiotherapy and possibly surgery, the prognosis is very good. After treatment, many young people are able to participate in sporting activities again without pain and with full mobility.
