A patellar dislocation is a knee injury in which the patella (kneecap) slips out of its normal position. [5] Often the knee is partly bent, painful and swollen . [ 1 ] [ 2 ] The patella is also often felt and seen out of place. [ 1 ]

A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
The incidence rate of initial patellar dislocations is roughly 32.8 per 100,000 person years. [39] Nearly 41% of knee dislocations have an associated fracture, with the majority of these fractures in one of the legs. [46] Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [46]
The kneecap is prone to injury because of its particularly exposed location, and fractures of the patella commonly occur as a consequence of direct trauma onto the knee. These fractures usually cause swelling and pain in the region, bleeding into the joint (hemarthrosis), and an inability to extend the knee. Patella fractures are usually ...

The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.
