The most common zone of injury after primary patellar dislocation in pediatric patients was isolated to the patellar attachment in a majority of patients, according to a study published in The American Journal of Sports Medicine.
Researchers examined patients under the age of 18 who suffered a medial patellofemoral dislocation, but who had no prior history of knee disorders. MRI scans of the 43 pediatric patients divided the medial patellofemoral ligament into groups: patellar insertion, femoral insertion and midsubstance.
In 61 percent of the cases, the injury was isolated to the patellar attachment, compared with 12 percent of the cases associated with the femoral attachment. Another 12 percent of the patients had both patellar and femoral tears. The MPFL insertion sit averaged about 5 millimeters and 86 percent of the patients had an MPFL associated with interdistal growth plates.
