Many different knee injuries can happen. Three percent of knee injuries are acute traumatic patellar dislocations.[1] Because dislocations make the knee unstable, 15% of patellas will redislocate.[2]

In the United States, men are most likely to sustain a finger dislocation with an incidence rate of 17.8 per 100,000 person-years.[3] Women have an incidence rate of 4.65 per 100,00 person-years.[3] The average age group that sustain a finger dislocation are between the ages of 15 to 19 years old.[3]

Anterior dislocations are less common than posterior dislocations. 10% of all dislocations are anterior and is broken into superior and inferior types. [4]Superior dislocations account for 10% of all anterior dislocations, and inferior dislocations account for 90%.[4] 16-40 year old males are more likely to receive dislocations due to a car accident.[4] When an individual receives a hip dislocation, there is an incidence rate of 95% that they will receive an injury to another part of the body.[4]
