Tibial plateau fractures are one of the most common fractures in knee trauma. Fractures of the tibial condyle can result from impingement of the knee from internal/external violence, or from compression violence caused by a fall. Because tibial plateau fractures are typically intra-articular, tibial plateau fractures are often associated with damage to the articular cartilage, knee ligaments or meniscus, and missed diagnosis and improper management can result in knee deformity, force line or stability problems, leading to joint dysfunction. The following are complications of tibial plateau fractures. 1. Knee stiffness: Restricted knee motion is more common after a plateau fracture. This intractable complication is due to damage to the knee extension device, damage to the articular surface from the original trauma, and soft tissue exposure done for internal fixation surgery. Postoperative braking further worsens these factors, and generally braking for more than 3 to 4 weeks can often result in some degree of permanent stiffness of the joint. 2, deformed healing because the tibial plateau is mainly composed of cancellous bone: surrounded by soft tissue attachment, with good blood supply and osteogenesis, the fracture is easy to heal, but due to premature weight bearing, resulting in collapse of the inner or outer condyle of the tibia; internal fixation is not secure, crushing fracture has defects, and insufficient bone grafting causes deformed healing, when the knee inversion > 5 °, valgus > 15 °, the patient walks with pain, should be immediately corrective surgery, such as Inverted V-shaped osteotomy is done 3cm below the tibial tuberosity. 3. The incidence of post-traumatic arthritis after platform fracture is still not very clear. However, several scholars have confirmed that the joint surface is not smooth and joint instability can lead to post-traumatic arthritis. The development of degenerative arthritis after fracture in young adults is not an ideal indication for artificial total knee replacement. If the arthritis is limited to the medial or lateral compartment, it can be corrected with osteotomy orthopedics; in cases of severe arthritis in two or three compartments, joint fusion or prosthetic arthroplasty is required. Age, range of motion of the knee, and the presence of infection play an important role in deciding whether to treat surgically.
