Fracture repair of the periarticular joint is one of the more difficult types of surgery in traumatic orthopedics. Poor fracture reduction, joint defects, and infection are the main complications, which can be catastrophic and very difficult to treat when they occur. Case Failure of internal fixation of knee plateau fracture with infection and non-healing wound Patient, male, 19 years old, failed internal fixation of knee plateau fracture, defective internal plateau, infection through the joint cavity, non-healing wound, and 0-20° joint mobility. The patient had already undergone 6 surgeries locally prior to the consultation. When I first met the patient, I felt a headache. It was very complicated reworking, the infection could not be controlled and the patient could only fuse the joint, the platform could not be repaired only joint replacement, both treatment options were a bit cruel for a 19 year old. After we controlled the infection with local drug release techniques, the joint was opened and seen with an internal plateau defect of nearly one-half. The joint was reconstructed with autologous iliac bone to restore the articular surface and reconstruct the joint. After the wound healed, the joint moved freely and the range of motion has been restored to 0-90°. I wish this child good luck. As a reminder, it is important to pay attention to the wound and not be careless until healing is determined.
