![]() The patient reported no history of illness or surgery, and no family members had any inherited diseases. Physical examination and lower limb computed tomography angiography confirmed normal neurovascular status. Initial management consisted of debridement and application of bone traction. The level of contamination was minimal, and there were no soft-tissue defects that needed to be covered with a flap. Two small open wounds were noted mainly on the anterior aspect of the mid-distal femur. A patellar fracture was observed in the ipsilateral knee. Patient characteristicsĪ 38-year-old man injured his left leg in a car accident, sustaining a closed intra-articular fracture of the proximal tibia and open intra-articular fracture of the distal femur with extension to the diaphysis. Data anonymity was maintained to protect patient privacy. The patient provided written informed consent for participation. The study was conducted in accordance with the principles outlined in the Declaration of Helsinki and was approved by the Ethics Committee of the Second Hospital of Jilin University. Minimally invasive techniques can provide a simple and effective treatment for some complex fractures. Final follow-up taken 3 years after surgery showed good lower limb alignment and complete plasticity of the bone structure, by which time the patient showed good limb function. Postoperative evaluation of the patient was satisfactory, with immediate functional exercise, full weight-bearing after three months, and return to daily activity without pain. The treatment strategy involved a locking plate system applying MIPO technology. The clinical diagnosis was closed intra-articular fracture of the proximal tibia, open intra-articular fracture of the distal femur with extension to the diaphysis, and a patellar fracture on the ipsilateral knee. Physical examination and computed tomography angiography of the lower limb confirmed that there was no damage to the neurovascular system. Case presentationĪ 38-year-old man injured his left leg in a car accident, causing pain, swelling, deformity, and limited mobility on his left knee and thigh, and two small open wounds were noted mainly of the anterior aspect of the mid-distal thigh. The purpose of this study was to demonstrate that minimally invasive plate osteosynthesis (MIPO) technology can simplify these complex problems and improve patient prognosis. In such cases, intra-articular fracture and the high degree of comminution and deformity of the mid-distal femur make fixation challenging. Floating knee type IIC, according to Fraser’s classification, is an uncommon severe injury that typically occurs in polytrauma.
