Who is susceptible to patellar dislocation?
Patellar dislocation primarily affects individuals between the ages of ten and 17, with equal likelihood in both males and females. Although relatively rare, it accounts for only two percent of knee injuries. Additionally, there appears to be a genetic predisposition, as around 24 percent of those who suffer from this injury have a family history of patellar dislocation.
Symptoms of Patellar Dislocation
Patellar dislocation can be identified by certain noticeable symptoms. One of the primary indications is the misalignment of the patella, which is commonly observed on the outside of the knee rather than the front, resulting in a distorted appearance. Another symptom is the bending of the leg when the hamstring muscle is flexed or tightened. However, in individuals with a patellar dislocation, the leg may bend even without any muscle flexion. Additionally, straightening the leg may become challenging or impossible for the affected person.
Other symptoms associated with patellar dislocation include knee and kneecap pain, bruising, and swelling. It is also common for the knee to give way when the individual tries to stand. Furthermore, the patella may exhibit hyper-mobility, causing it to slide around the front of the knee joint.
