A comminuted fracture of the distal femur is a severely damaging fracture. It is usually recommended that the patient have the internal fixation removed about one year after the operation after the plate has been applied. If there are special circumstances, it may need to be removed earlier or later. Comminuted fracture of distal femur is often caused by violence or fall from height, etc. It is often accompanied by large amount of blood loss or open injury, and requires surgical treatment, such as cut-and-replace locking intramedullary nail fixation, etc. The fracture can be almost fixed by 3 months after surgery. The fracture can be basically healed in 3 months after the surgery and can be normally moved down to the ground, but it will take some time for the bone to fully recover and reach a solid state. Therefore, it is generally recommended that patients remove the internal fixation plate after one year. If the plate breaks, the screw loosens, or the foreign body rejects the reaction, which affects walking, the plate can be removed earlier if the fracture heals well after 3 months of fracture surgery. If the fracture heals poorly, or if complications such as infection occur, the removal of the plate may be delayed. The timing of plate removal after distal femur comminuted fracture surgery should be decided according to the individual’s recovery condition, and the surgeon should be consulted for details.
