Total Knee Arthroplasty to Treat Acute Knee Dislocation Associated With Osteoarthritis: a Case Report

Background: Knee dislocation (KD) is a common disease in the young people. It is rare to report treatment of the KD associated with osteoarthritis (OA) in the old population. In this case report, we present two cases in which total knee arthroplasty (TKA) was performed to treat acute KD associated with osteoarthritis (OA) in two female patients. Methods: The two patients underwent knee injuries and limited range of motion (ROM). After diagnosing acute KD, including KD II and KD III-M, associated with OA with X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) investigations, we considered TKA to be the best management.Results: TKA was successfully used to treat acute KD associated with OA, and the patients achieved significant improvements in their clinical and functional outcomes.Conclusion: Acute KD associated with OA could be an indication for TKA. However, early TKA procedures can lead to a risk of arthrofibrosis and joint stiffness.Level of evidence V.
