Patella Dislocation usually occurs as a result of sudden direction changes while running when the knee is under stress or occasionally as a direct result of impact injury.

Doctors are at odds to the best way to remedy this injury, with splints, bandage and cast all with their supporters. All doctors agree however that a period of 3 weeks immobilisation is essential followed by another three weeks of physiotherapy.

In general, surgery is more effective in preventing recurrences of dislocation because skeletal and muscular components of the patellofemoral joint and extensor mechanism are realigned; however, surgery also has risks. In a patient with normal anatomy, surgery should be considered an option after all conservative treatments are unsuccessful.

So there you go.
