Patellofemoral Instability (Kneecap dislocation)

Patellofemoral Instability (Kneecap dislocation)

What is the patellofemoral joint?

The patellofemoral joint is where the back of your patella (kneecap)and femur (thigh bone) meet at the front of your knee. This area is important in transmitting the force from the big thigh muscle (quadriceps) across the knee joint.


It can become troublesome after an injury or when an individual’s natural anatomical make up makes it inherently more unstable.

Treatment and Prognosis

In some instances an isolated kneecap dislocation and instability event can be successfully managed with rehabilitation and strengthening. There are also individuals who despite good initial conservative treatment and physiotherapy run into difficulties with recurring / multiple dislocations and instability symptoms. This may be an indicator where a surgical intervention is appropriate through surgical stabilisation known as MPFL reconstruction.
