I : I would like to hear more details about what you are describing as a knee dislocation. True knee dislocations usually happen in major traumas where a significant force is required to disrupt the articular of the femur with the tibia (the knee joint). Far more common is a patellar subluxation. The patella is also called the kneecap. Usually this is felt as a clunking sensation in the knee, that "pops back in" when the knee is straightened. Sometimes the patella subluxes (slides out of its normal anatomic position) and then quickly returns to its normal position. This is perhaps more common in adolescents and young people. The first dislocation makes you prone to the next and those that follow. Beyond that, certain differences in limb alignment and rotation can predispose the patella to subluxate or dislocate. Prevention depends on what is causing it. After a first subluxation, the typical treatment is a short period of immobilization with the knee in extension to allow the retinacular structures to scar down and heal. With recurrent dislocations, there are a number of surgical procedures that could be used to address this problem. Physical therapy to strengthen the vmo (vastus medialis obliquus) may also be recommended by some, but usually for a first time dislocator.

Patella dislocation: Dislocation of the patella is different than "dislocating your knee". The patella pops out from direct trauma or a "knock knee" (valgus) alignment. Recurrent dislocations can be fixed with surgery to realign the knee.
