Patellar Dislocation
Patella also call as kneecap which lies in front of knee joint joint and protect the joint .
In healthy individual , upon flexion of the knee , the patella gliding up and down a groove called the genus Patella - femoral groove .
Quadriceps tendon is attached to kneepan . Patella increases the leveraging of quadriceps heftiness during knee joint movements such as straightening and extension .
Patellar disruption is abide by when the genus Patella mistake or moves outside this groove into the bony head of the femur ( lateral femoral condyle ) . genu harm most often causes patellar subluxation ( partial dislocation ) .
Patellar dislocation often results from a severe puff or from a twisting action of the articulatio genus .
Patellar dislocation is ab initio treated with physical therapy and renewal lasting six to sixteen weeks . Patient is give notice to consider operating theatre if conservative treatment fails .
Most of the time after accidental breakdown the patella will move back to its normal lieu with straighten to the knee . Procedure is extremely painful and may need sedation .
Investigation forPatellar Dislocation :
X - re will show the sidelong dislocation of the patella . X - ray is also use to evaluate the displacement of osteochondral fragments , which may point emergency operative treatment is necessary .
Frequent Patellar Dislocation : perennial patellar dislocation is mostly on lateral side and individuals will skid kneepan manually into normal military position while extending their leg .
peril factor of Patellar Dislocation :
Insufficient Vastus Medialis Obliquus or VMO long suit – The subprogram of the VMO ( vastus medialis obliquus ) is to maintain the patella in its normal position within the patellofemoral groove by pull it towards the heart and soul of the knee joint at the time of knee joint move . This is known as ‘ tracking ’ . If the muscle or its fibers are not strong or sufficiently point , then the patella becomes more prone to luxate .
Q - slant – is the slant between femoris or thigh and tibia or lower leg .
Genu Valgus – Genu Valgus is anatomic abnormality of knee stick because of increase Q slant . Patient hurt with genu valgus may push kneecap towards outside result in dislocation or subluxation ( fond breakdown ) while straightening their wooden leg or when extravagant effect is applied to the inside of the knee joint .
Patella Alta – is a low size kneecap and it is a birth defects . The precondition affects mobility and leg strength .
Treatment forPatellar Dislocation :
bourgeois Treatments for Patellar Dislocations are :
RICE therapy can be apply to the affected knee .
surgical procedure
