A patellar dislocation is a knee injury in which the patella (kneecap) slips out of its normal position.
Patellar dislocations occur with significant regularity, particularly in young female athletes.

Patellofemoral pain syndrome

An effective rehabilitation program reduces the chances of re-injury and of other knee-related problems such as patellofemoral pain syndrome and osteoarthritis.
The Q-angle, lateral hypermobility, and J-sign are commonly used determined to determine patellar maltracking.

A predisposing factor is tightness in the tensor fasciae latae muscle and iliotibial tract in combination with a quadriceps imbalance between the vastus lateralis and vastus medialis muscles can play a large role, found, mainly, in women with higher level the physical activity.

Pathophysiology

The pathophysiology of the kneecap is complex, and deals with the osseous soft tissue or abnormalities within the patellofemoral groove.

Dysplasia

The patellar symptoms cause knee extensor dysplasia, and sensitive small variations affect the muscular mechanism that controls the joint movements.

Genu valgum

People who have larger Q angles tend to be more prone to having knee injuries such as dislocations, due to the central line of pull found in the quadriceps muscles that run from the anterior superior iliac spine to the center of the patella.

Attenuated patella alta

In patella alta, the patella sits higher on the knee than normal.

Femur

femorathigh bonefemoral
Another cause that patellar dislocation can occur is when the trochlear groove that has been completely flattened is defined as trochlear dysplasia. It rests in the patellofemoral groove, an articular cartilage-lined hollow at the end of the thigh bone (femur) where the thigh bone meets the shin bone (tibia).

Tendon

The patella is a triangular sesamoid bone which is embedded in tendon.
