Post-Traumatic Total Knee Arthroplasty: A Case of Hoffa Fracture Nonunio‎n and Review of Literature

Background: Post-traumatic arthroplasty is associated with higher rates of complications and overall inferior outcome when compared with primary joint replacement. Literature revealed no precise guidelines on management of nonunio‎n of Hoffa fracture. Hence, we tried to elicit a management protocol in such patients from literature perspective. Case Presentation: A 62-year-old patient survived a car accident with distal femoral fracture in coronal plane (Hoffa fracture) and was treated with open reduction and internal fixation (ORIF). Three years later, the patient developed nonunio‎n with post-traumatic arthritis (PTA). Owing to joint degeneration and poor bone quality, patient was treated with total knee arthroplasty (TKA). One year follow-up showed excellent outcome. Conclusions: In patient with healthy joint surface and good bone density, treatment of choice should be ORIF and in those with joint degeneration and low bone stock, arthroplasty is a better choice.
