Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.

Abstract
Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.
